** The number is visible cycles of ringing is a guide to the Q of a resonant
circuit - the Q is approximately equal to the number of cycles.
So, your pickup coil has about a Q of 4 - either bare or assembled.
Why?
The frequency of ringing is much higher when bare.
Q = the ratio of impedance to resistance at a given frequency.

I'm guessing that you're unfamiliar with the Sencore Z-Meters Ringer Tests.
They're capable of indicating shorted single turns.
Fault-free inductors normally ring 10 rings or higher.
Placing a single turn of wire (with ends touching forming a conductive turn)
around an inductor will generally yield a Fail/1-thru-9 test result.
These testers work reliably for any type of inductor/transformer commonly
used in electronic equipment circuits (no core material or ferrite-type
cores, not steel core types as mentioned previously).
Guitar pickup assemblies aren't typical circuit inductors, however I kinda
expected them to Ring Test normally with the steel screws and cores removed.

The element is inside a metal oven. How long do you think it will
take for the defctive element to burn a hole in it? How long before the
breaker would trip or the fuse would open on their own?

How long was the problem festering before the user noticed?
If it doesn't matter how long it takes for the user to reach the circuit
breaker, then it doesn't matter if they don't bother.
An ELT would trip straight away, if one's fitted, which it might not be
in this kind of circuit. There's no guarantee that there'd ever be an
overcurrent trip.

Festering? Get real. We aren't talking low temperature an a few mA.

Emergency Locator Transmitter?
Extremely Large Telescope?
These are the only uses of 'ELT' I've seen in the United States. It
is where I live, and so does the OP.
Sigh. Think it through. The body of the oven is grounded. If a
calrod element is failing, it isn't gradual. If it shorts to the metal
body the fuse blows, or the breaker trips since it is less than a full
load resistance.
If the element opens inside the metal tube, it generally creates
plasma which burns through the casing and opens the element
permanently. Even a bad connector will self destruct at those currents.
There is an exceedingly small chance for an intermittent element.

In all the years that I was directly involved with with TV sets in the UK,
working for one of the big four rental companies, I can only ever remember
one TV "going up in flames". It most certainly was not a common or frequent
occurrence. Further, I don't think I can recall any commonly sold make or
model, which ever employed an earth connection to the chassis. As for power
cords not being polarised, it depends exactly what you mean by that. In the
very early days, there were some sets that used a two pin plug-in power lead
which could be reversed. Likewise, there were two pin power sockets which
again could have the plugs for them reversed. However, by the time TV was
firmly established in the UK as an 'in every home' item, these sets were
long gone, and fixed power leads with colour-polarised wires, were the norm.
When we went over to the 13 A three pin wall socket convention, then as long
as the plug had been wired correctly, a 'live chassis' TV could never
actually have its chassis connected to the 'live' side of the incoming line
power. As to the chassis being live " even when the TV was turned off ", the
vast majority of sets that I saw employed a two pole power switch, ganged to
the volume control, so when they were switched off, both the line and the
neutral wires were disconnected from the TV.
On the cooker isolation issue, here in the UK, electric cookers are
typically connected via a permanently wired power cord that goes to a custom
outlet plate specifically designed and sold for the purpose. It is usual for
that outlet plate to be well down the wall behind the cooker, but connected
inside the wall to a further 'panel' mounted above counter height. On this
panel is either a large red switch on its own, or a large red switch, and a
three pin conventional power outlet. This is the double pole isolation
switch for the cooker, and is in addition to the fuse and breaker covering
this (independent) circuit, back at the fuse board.

Let's take a look at what will happen if the heating element fails by
shorting from the resistance element to the sheath. I will assume
that the failure I observed is worst case - an actual arc formed.
This gradually (1-2" per minute) moved toward the end of the heating
element. As the length of the resistance element got shorter, the
current would rise. Eventually the circuit breaker would trip. The
chance of a fire was very small. Most modern kitchen ranges have self
cleaning ovens which clean by heating themselves up high enough the
grease and spills are oxidized.
As I stated before, the problem was not in the design. Granted,
William Sommerwerk would not have received a shock if both lines were
interuurpted. However, that's not absolute protection. Switch and
relay contacts do weld together, triacs do short. One particular
brand of circuit breaker has been banned because the contacts tend to
weld together.
The chain of events is simple - The range was designed to meet certain
standards. William Sommerwerk assumed it was designed to his
standards. What is more, he was so confident in his assumption, he
failed to take the most emementary precaution of actually testing that
the terminal was not live.
Perhaps some may feel I am paranoid, but I have observed enough cases
where things were not as they should have been that I don't trust
labels, nor do I trust circuit breakers. Heck, I don't even trust a
simple neon bulb tester unless I check it!!
I've seen licensed electricians swap live and neutral wires in an
outlet box. I've seen a breaker box where the position labeled
'range' actually held two 15 amp breakers. I've seen a 12 gauge
(rated for 20 Amps) wire hooked to a 45 amp circuit breaker. I've
seen 'TN' wires (for installation in a conduit) strung across an attic
to power a ceiling fan in the room below.

There are adjustments for this, older sets use potentiometers, newer ones
set values of drive, cutoff etc in memory and are adjusted through the
"servicer menu", a hidden function accessed by a certain string of button
presses on the remote. Not given to consumers because there are so many
technical adjustments that would just mess up the set if messed with by the
unknowledgeable.

The most-likely explanation is that the bias on the blue gun is drifting
"upward", so the darker areas of the picture are turning blue. You don't
need to understand the circuits to fix the problem. (I could make a
wisecrack, but I won't.)
This is easily fixable, if the set has potentiometers on the back. You're
looking for the one marked "blue screen", or something similar. You need to
turn it down (CCW, presumably) a bit.
Mark pointed out that some sets use a software-based system, which requires
gaining access to the service menu. Regardless, browse the manual to find
the "setup" section.

Swapping the drive for blue and red gun , say , will show if its a problem
with the drive or the output stage.

That depends on how the set is set up. If three separate cathodes and
grids, maybe ok. If a common cathode for all three guns, also maybe
ok. But neither is a sure thing.

As is typical of all UseNet groups, this discussion is wandering.
We have given the OP the basic information he needs to get started. (I would
also recommend he read a book on color TV operation and servicing.) He needs
to look through the service manual for information about setting up the
set's "tracking". Once he's done that, and perhaps fiddled a bit more with
the set, he can come back and ask more questions.

I suspect that your motor is a DC fan motor.
FWIW, my Fujitsu ducted aircon has a 7-wire fan motor driven by the
indoor unit, and two 5-wire fan motors driven by the outdoor unit.
The indoor fan has three wires to select low (990 RPM, blue), medium
(1150 RPM, violet), or high speed (1300 RPM, red). A 20uF 370V start
capacitor connects to the black and white wires, and power is also
supplied on the white wire.
The outdoor fan motors are DC types. The wire colours are Red, Black,
White, Yellow and Brown. They run at 850 RPM (up Fan) and 750 RPM
(down Fan).
Red = DC power
Black = Ground
White = +15VDC
Yellow = Power On
Brown = Feedback
The following Fujitsu service manuals have circuit diagrams that may
help you understand the drive requirements:

It may also be worth looking at LG service manuals:

From: bv
THE MERITS OF ISLAM
There are many religions so why do Muslims think that Islam is true?
Is there any factual basis?
This is a reasonable enough question for one who has not entered
Islam, but one who believes in and practices this religion already
knows the blessings which are his because of this religion. There are
many reasons for this, which include the following:
(1) The Muslims worship Allah, Who has no partner, and Who has the
most beautiful names and the highest attributes. Thus the Muslim's
focus and aim is concentrated, focused on His Lord and Creator; he
puts his trust in Him and asks Him for help, patience and support; he
believes that Allah is able to do all things, and has no need of a
wife or son. Allah created the heavens and earth; He is the One Who
gives life and death; He is the Creator and Sustainer from Whom the
slave seeks provision. He is the All-Hearing Who responds to the
supplication of His slave, and from Whom the slave hopes for a
response. He is the All-Merciful and All-Forgiving, to Whom the slave
turns in repentance when he has committed a sin or fallen short in his
worship of Allah. He is the Omniscient and All-Seeing, who knows all
intentions and what is hidden in people's hearts. The slave feels
ashamed to commit a sin by doing wrong to himself or to others,
because his Lord is watching over him and sees all that he does. He
knows that Allah is All-Wise, the Seer of the Unseen, so he trusts
that what Allah decrees for him is good; he knows that Allah will
never be unjust to him, and that everything that Allah decrees for him
is good, even if he does not understand the wisdom behind it.
(2) The effects of Islamic worship on the soul of the Muslim include
the following:
Prayer keeps the slave in contact with his Lord; if he enters it in a
spirit of humiliation and concentration, he will feel tranquil and
secure, because he is seeking a "powerful support," which is Allah,
may He be glorified and exalted. For this reason, the Prophet of
Islam, Muhammad peace be upon him used to say: "Let us find relaxation
and joy in prayer." If something distressed him, he would hasten to
pray. Everyone who finds himself faced with disaster and trials prayer
finds strength, patience and consolation for him because he is
reciting the words of his Lord, which cannot be compared to the effect
of the words of a created being. If the words of some psychologists
can offer a little comfort, what do you think of the words of the One
Who created the psychologist?
Now let us look at Zakaat, which is one of the pillars of Islam.
Zakaat purifies the soul from stinginess and miserliness, and
accustoms people to being generous and helping the poor and needy. It
will bring a great reward on the Day of Resurrection, just like other
forms of worship. It is not burdensome, like man-made taxes; it is
only 25 in every thousand, which the sincere Muslim pays willingly and
does not try to evade or wait until someone chases him for it.
Fasting involves refraining from food and sex. It is a form of
worship, and a way in which one can feel the hunger of those who are
deprived. It is also a reminder of the blessings of the Creator, and
it brings rewards beyond measure.
Hajj is the Pilgrimage to the sacred House of Allah, which was built
by Ibrahim peace be upon him. By performing Hajj one is obeying the
command of Allah and the call to come and meet Muslims from all over
the world.
(3) Islam commands all kinds of good and forbids all kinds of evil. It
encourages good manners and proper treatment of others. It enjoins
good characteristics such as truthfulness, patience, deliberation,
kindness, humility, modesty, keeping promises, dignity, mercy,
justice, courage, patience, friendliness, contentment, chastity, good
treatment, tolerance, trustworthiness, gratitude for favours, and self-
control in times of anger. Islam commands the Muslim to fulfil his
duty towards his parents and to uphold family ties, to help the needy,
to treat neighbours well, to protect and safeguard the wealth of the
orphan, to be gentle with the young and show respect to the old, to be
kind to servants and animals, to remove harmful things from the road,
to speak kind words, to forgive at the time when one has the
opportunity to take revenge, to be sincere towards one's fellow-
Muslims, to meet the needs of the Muslims, to give the debtor time to
repay his debt, to prefer others over oneself, to console others, to
greet people with a smiling face, to visit the sick, to support the
one who is oppressed, to give gifts to friends, to honour his guest,
to treat his wife kindly and spend on her and her children, to spread
the greeting of peace (salaam) and to seek permission before entering
another person's house, lest one see something private that the other
person does not want one to see.
Some non-Muslims may do these things out of politeness or good
manners, but they are not seeking reward from Allah or salvation of
the Day of Judgement.
If we look at what Islam has prohibited, we will find that it is in
the interests of both the individual and society as a whole. All these
prohibitions serve to safeguard the relationship between the slave and
his Lord, and the relationship of the individual with himself and with
his fellow-man. The following examples demonstrate this:
Islam forbids the association of anything in worship with Allah and
the worship of anything other than Allah, because this spells doom and
misery. Islam also forbids visiting or believing soothsayers and
fortune-tellers; magic or witchcraft that may cause a rift between two
people or bring them together; belief in the influence of the stars on
events and people's lives; cursing time, because Allah is directing
its affairs; and superstition, because this is pessimism.
Islam forbids canceling out good deeds by showing off, boasting or
reminding others of one's favours; bowing or prostrating to anything
other than Allah; sitting with hypocrites or immoral people for the
purposes of enjoying their company or keeping them company; and
invoking the curse or wrath of Allah on one another or damning one
another to Hell.
Islam forbids urinating into stagnant water; defecating on the side of
the road or in places where people seek shade or where they draw
water; from facing the Qiblah (direction of prayer) or turning one's
back towards it when passing water or stools; holding one's penis in
one's right hand when passing water; giving the greeting of salaam
(peace) to one who is answering the call of nature; and putting one's
hand into any vessel before washing it, when one has just woken up.
Islam forbids the offering of any nafl (supererogatory) prayers when
the sun is rising, when it is at its zenith, and when it is setting,
because it rises and sets between the horns of Shaytaan (Satan);
praying when there is food prepared that a person desires; praying
when one urgently needs to pass water, stools or wind, because that
will distract a person from concentrating properly on his prayer.
Islam forbids the Muslim to raise his voice in prayer, lest it disturb
other believers; to continue offering supererogatory prayers at night
when one feels drowsy -such a person should sleep then get up; to stay
up all night in prayer, especially one night after another; and to
stop praying when there is doubt as to the validity of one's wudoo' -
unless one hears a sound or smells an odour.
Islam forbids buying, selling and making "lost and found"
announcements in the mosque - because it is the place of worship and
remembrance of Allah, where worldly affairs have no place.
Islam forbids haste in walking when the iqaamah (call immediately
preceding congregational prayer) is given, and prescribes walking in a
calm and dignified manner. It is also forbidden to boast about the
cost of building a mosque; to decorate a mosque with red or yellow
paint or adornments which will distract the worshippers; to fast day
after day without a break; and for a woman to observe a supererogatory
fast when her husband is present without his permission.
Islam forbids building over graves, making them high, sitting on them,
walking between them wearing shoes, putting lights over them or
writing on them. It is forbidden to disinter the dead or to take
graves as places of worship. Islam forbids wailing, tearing one's
clothes or leaving one's hair unkempt when a person dies. Eulogizing
the dead in the manner of the times of Ignorance (Jaahiliyyah) is also
forbidden, although there is nothing wrong with informing others that
a person has died.
Islam forbids the consumption of riba (interest); all kinds of selling
which involve ignorance (of the product), misleading and cheating;
selling blood, wine, pork, idols and everything that Allah has
forbidden - their price, whether bought or sold - is haraam; which is
offering a price for something one has no intention of buying, as
happens in many auctions; concealing a product's faults at the time of
selling; selling something which one does not own or before it comes
into one's possession; undercutting, outbidding or out bargaining
another; selling produce before it is clear that it is in good
condition and free of blemish; cheating in weights and measures; and
hoarding. A partner who has shares in a plot of land or a date palm
tree is forbidden to sell his share without consulting his partners.
It is forbidden to consume the wealth of orphans unjustly; to bet or
gamble; to take anything by force; to accept or offer bribes; to steal
people's wealth or to consume it unjustly; to take something for the
purpose of destroying it; to undermine the value of people's
possessions; to keep lost property which one has found, or to keep
quiet about it and not announce it, for it belongs to the one who
recognises it; to cheat in any way; to ask for a loan with no
intention of repaying it; to take anything of the wealth of a fellow-
Muslim, unless it is given freely, because what is taken because of
another person's shyness is haram; and to accept a gift because of
intercession.
Celibacy and castration are forbidden, as is marrying two sisters, or
a woman and her aunt (paternal or maternal), whether he marries the
aunt after marrying her niece or vice versa, for fear of breaking the
ties of kinship. It is forbidden to make deals in marriage, such as
saying "Let me marry your daughter and I will give you my daughter or
sister in marriage." Such reciprocal deals are a form of oppression
and injustice, and haram. Islam forbids mut'ah (temporary marriage),
which is a marriage contract for a period of time agreed by the two
parties, at the end of which the marriage expires. Islam forbids
intercourse with a menstruating woman, until she has purified herself
(by taking a bath after her period ends), and also forbids anal
intercourse. A man is forbidden to propose marriage to a woman when
another man has already proposed to her, unless the other man
withdraws his proposal or gives him permission. It is forbidden to
marry a previously-married woman without consulting her, or a virgin
without seeking her permission. It is forbidden to wish (a newly
married couple) "Bi'l-rafaa' wa'l-baneen (a joyful life and many
sons)," because this is the greeting of the people of Jaahiliyyah, who
hated daughters. The divorced woman is forbidden to conceal what Allah
has created in her womb (if she is pregnant). A husband and wife are
forbidden to speak (to others) about the intimacies of married life.
It is forbidden to turn a woman against her husband or to take divorce
lightly. It is forbidden for a woman to ask for another's divorce,
such as asking a man to divorce a woman so that she can marry him. A
wife is forbidden to spend her husband's money without his permission,
or to keep away from his bed without good reason, because the angels
will curse her if she does that. A man is forbidden to marry his
father's wife, or to have intercourse with a woman who is pregnant
from another man. It is forbidden for a man to practise 'azl (coitus
interrupts) with his free wife without her permission. It is forbidden
for a man to return home from a journey late at night and startle his
family, unless he has previously notified them when he will arrive
home. A man is forbidden to take anything of his wife's mahr (dowry)
without her consent, or to keep annoying his wife so that she will
give up her wealth.
Islam forbids women to make a wanton display of themselves (tabarruj).
Women are forbidden to admit anyone into their husband's home without
his permission; his general permission is acceptable so long as they
stay within the limits of sharee'ah. It is forbidden to separate a
mother and child (in case of divorce); to let one's womenfolk behave
foolishly (in an immoral fashion) and not say anything; to let one's
gaze wander everywhere; and to follow an accidental glance with an
intentional glance.
Islam forbids the eating of dead meat, regardless of whether it died
by drowning, strangulation, shock or falling from a high place; eating
blood, pork and anything slaughtered in a name other than that of
Allah or for idols; eating the flesh or drinking the milk of beasts
that feed on filth and waste matter; eating the flesh of every
carnivorous beast that has fangs and every bird that has talons;
eating the meat of domesticated donkeys; killing animals by keeping
them and throwing stones at them until they die, or detaining them
without food until they die; slaughtering with teeth or nails;
slaughtering one animal (for food) in front of another; or sharpening
the knife in front of the animal to be slaughtered.
In the area of clothing and adornment, men are forbidden the
extravagance of wearing gold. Muslim are forbidden to be naked or to
expose their thighs; to leave their clothes long (below the ankles)
and trail them on the ground for the purpose of showing off; and to
wear clothes that will attract attention.
It is forbidden to bear false witness; to make false accusations
against a chaste believing woman; to accuse someone who is innocent;
to utter lies; to slander and backbite; to call people by offensive
nicknames; to spread gossip and malicious slander; to make fun of the
Muslims; to boast about one's status; to shed doubts on a person's
lineage; to utter slander, insults and obscenities; to speak in an
indecent or rude manner; or to utter evil in public, except by one who
has been wronged.
Islam forbids telling lies; one of the worst kinds of lie is to lie
about dreams, like fabricating dreams and visions in order to prove
one's virtue, or make some material gains, or to frighten an enemy.
Muslims are forbidden to praise themselves, or to talk in a secret
way: two may not converse secretly to the exclusion of a third,
because this is offensive. It is forbidden to curse a believer or
someone who does not deserve to be cursed.
Islam forbids speaking ill of the dead; praying for death; wishing for
death because of some suffering that one is passing through; praying
against one's self, one's children, one's servants or one's wealth.
Muslims are told not to eat the food that is directly in front of
others or to eat from the centre of the dish or platter; rather they
should eat from what is directly in front of them or thereabouts,
because the barakah (blessing) comes in the middle of the food. It is
forbidden to drink from a broken edge of a vessel, because this could
cause harm; or to drink from the mouth of a vessel; or to breathe into
it. It is forbidden to eat while lying on one's stomach; to sit at a
table where wine is being drunk; to leave a fire burning in one's
house when one sleeps; to sleep with Ghamr in one's hand, like an
offensive smell or the remainder of food (grease); to sleep on one's
stomach; or to talk about or try to interpret bad dreams, because
these are tricks of the Shaytaan.
It is forbidden to kill another person except in cases where it is
right to do so; to kill one's children for fear of poverty; to commit
suicide; to commit fornication, adultery or sodomy (homosexuality); to
drink wine, or even to prepare it, carry it from one place to another,
or sell it. Muslims are forbidden to please people by angering Allah;
to offend their parents or even to say "Uff" (the slightest word of
contempt) to them; to claim that a child belongs to anyone but his
real father; to torture by means of fire; to burn anyone, alive or
dead, with fire; to mutilate the bodies of the slain; to help anyone
commit falsehood; or to co-operate in wrongdoing and sin.
It is forbidden to obey any person by disobeying Allah; to swear
falsely; to swear a disastrous oath; to eavesdrop on people without
their permission; to invade people's privacy or look at their private
parts; to claim something that does not belong to one or that one did
not do, for the purpose of showing off; to look into someone's else's
house without permission; to be extravagant; to swear an oath to do
something wrong; to spy on others or be suspicious about righteous men
and women; to envy, hate or shun one another; to persist in falsehood;
to be arrogant or feel superior; to be filled with self-admiration; to
be pleased with one's arrogance. Islam forbids taking back one's
charity, even if one pays to get it back; employing someone to do a
job without paying him his wages; being unfair in giving gifts to
one's children; bequeathing everything in one's will and leaving one's
heirs poor - in such a case the will should not be executed; writing a
will that concerns more than one third of one's legacy; being a bad
neighbour; or changing a will to the detriment of one or some of one's
heirs. A Muslim is forbidden to forsake or shun his brother for more
than three days, except for a reason sanctioned by sharee'ah; to hold
small stones between two fingers and throw them because this could
cause injury to eyes or teeth; to include his heirs in a will, because
Allah has already given heirs their rights of inheritance; to disturb
his neighbour; to point a weapon at his Muslim brother; to hand
someone an unsheathed sword, lest it harm him; to come (walk) between
two people except with their permission; to return a gift, unless
there is some shar'i objection to it; to be extravagant; to give money
to foolish people; to wish to be like someone to whom Allaah has given
more of something; to cancel out his charity by giving offensive
reminders of his giving; to wilfully conceal testimony; or to oppress
orphans or scold one who asks for help or money. It is forbidden to
treat with evil medicines, because Allah would not create a cure for
this Ummah which includes something that He has forbidden. It is
forbidden to kill women and children in warfare; to boast to one
another; or to break promises.
Islam forbids betraying a trust; asking for charity that one does not
need; alarming a Muslim brother or taking away his possessions,
whether jokingly or seriously; changing one's mind after giving a
gift, except in the case of a gift from a father to his child;
practising medicine without experience; or killing ants, bees and
hoopoe birds. A man is forbidden to look at the 'awrah (private parts)
of another man, and a woman is forbidden to look at the 'awrah of
another woman. It is forbidden to sit between two people without their
permission; or to greet only those whom one knows, because the
greeting is to be given to those whom you know and those whom you do
not know. A Muslim is forbidden to let an oath come between him and
good deeds; he should do what is good and make expiation for the oath.
It is forbidden to judge between two disputing parties when one is
angry, or to judge in favour of one party without hearing what the
other has to say. It is forbidden for a man to walk through the market-
place carrying something - like a sharp weapon - that could harm the
Muslims, unless it is properly covered. A Muslim is forbidden to make
another person get up, so that he can take his place.
There are more commands and prohibitions which came for the benefit
and happiness of individuals and mankind as a whole. Have you ever
seen any other religion that can compare to this religion?
Read this response again, then ask yourself: is it not a great pity
that I am not one of them? Allah says in the Qur'an (interpretation of
the meaning):
"And whoever seeks a religion other than Islam, it will never be
accepted of him, and in the Hereafter he will be one of the
losers." [Aal 'Imraan 3:85]
Finally, I hope that everyone who reads this will be guided to the
correct way and to follow the truth. May Allah protect you and us from
all evil.

First I want to say sorry if this is the wrong usenet group but here's
my problem: Air conditioner is a 7 year old Sunpentown WA-1210E. The
tank fills (and turns itself off as it should) in only 4 hours. I can
only drain out half of its 3 pint capacity. It cools fine however.
It's never required draining before, except as reccomended at the end
of summer. I've googled for tips and have tried adding a small amount
of bleach to through the drain plug hole after draining but problem
repeats. Thanks in advance for a solution.
