Which is damned with faint praise, if ever there were. Phil, were he to behave "at home" as he does "away" on this group would be, rapidly, rendered incapacitated, probably on a permanent basis. There is some significant pathology going on there, rendering Phil a figure to be pitied. I am as good with invective and vituperation as the next guy, here, and seldom find the need to use vulgarity. But, Phil is one sort of special case, being as that is all he has. And Tabby is another sort of special case, as he *must* find the exceptional case for everything. Which, at the very least, gets tiresome. Peter Wieck Melrose Park, PA |

In fairness, pretty much all guns are handled at some point, and a LOT of people drive drunk daily. And like mains voltages, pretty much everyone knows guns and drunk driving are and is dangerous.

| Look165 <look165@numericable.fr>: Mar 25 05:59PM +0100 The only guilty part can be : mains transtormer, HV diode and HV capacitor. A magnetron never dies. A HV diode cannot be checked with standard tools. The best is to check the HV at the cap (take care to your hands). It must be some 10 kV or more. For heating, refer to your control board.

But I'd better just check the magnetron first....... > :-/ What did you use to check the diode ? Many of the high voltage diodes are actually several in series in the same package. Most meters will not check them as there are several volts dropped across them. The meters will often show them as open in both directions evenif they are good. |

Aside from sprinkling bits of technical troubleshooting and safety advice in a string of email exchanges, I was reminded of this comprehensive 'Microwave repair' document. Should be read and understood before one even unplugs the device to be repaired. (When one considers that the charge stored in the microwave capacitor is significantly (x10+) the charge from public defibrillators (AEDs) the energy is definitely high enough to put a human being horizontal - permanently!) https://www.repairfaq.org/sam/micfaq.htm#micpre j |

Yep. The normal "diode check" found on most meters doesn't work. I usually get about 100Kohms in the forward direction and infinity in the reverse on my Simpson 260 meter (which uses a 15v battery for the high resistance scales): <https://www.partselect.com/Microwave+test-diode+repair.htm> Or, use a 9V battery <https://www.youtube.com/watch?v=1pp4LUrq4DM> <https://www.youtube.com/watch?v=F1mTElvwcBg> <https://www.youtube.com/watch?v=R7wpRRU8vEY> If the microwave oven doesn't kill you, perhaps the popcorn will?

There are two (safe) checks to test a magnetron: resistance between pins both ways round should be less than 1ohm and resistance between each pin and the 'tron case should be open-circuit. -- This message may be freely reproduced without limit or charge only via the Usenet protocol.

| David Farber <farberbear.unspam@aol.com>: Mar 25 10:28AM -0700 This Dell Inspiron N5110, which has Windows 7 Home Premium installed, was given to me because upon startup it would BSOD with a REGISTRY_ERROR. That was resolved with a system restore but I noticed another problem which has me puzzled. The system time does not advance when the unit is turned off. I went into the BIOS setup and noticed that within the time configuration, the seconds were not ticking. Once the machine is booted into Windows, the automatic time synchronization will eventually set it to the correct time and it stays that way until it's powered off. The CMOS battery measures above 3 volts in circuit and all the other BIOS settings are saved when the machine is off. I tried temporarily removing the battery to reset the BIOS and the result was that the time reverted back to several years earlier however the seconds were ticking normally. I entered the correct time/date and restarted the computer and all was well. I turned it off for a while and then powered it on again and entered the BIOS setup. The time was stuck again and the seconds were not advancing. It seems to me that no matter what condition the Windows operating system is in, it shouldn't be able to interrupt the time function when the set is powered off. I tried updating the BIOS to a newer version but that just crashed the machine. (Fortunately it didn't brick the machine). I found other users complaining about the frozen clock issue but as yet have found no solution. Here is an example of a similar complaint. https://www.dell.com/community/Laptops-General-Read-Only/date-time/td-p/4122751 Anyone have any ideas what is causing this suspension of time? Thanks for your reply. -- David Farber Los Osos, CA |

Hi Mike, The CR2032 battery is not rechargeable and it is not measuring below 3.0 volts.

| Look165 <look165@numericable.fr>: Mar 26 01:07PM +0100 The main cause, as explained, is the battery (CR2032). You need to change it. It causes also BSOD. David Farber a écrit le 25/03/2019 à 18:28 : |
