Ya know, you're gonna have to take it down to fix it anyway.
You didn't say if you tried another set of batteries after
they died. Or rather than buy yest another set, since you
have to pull it down one way or the other, put in another set
and see if the weather station works.

I guess you just want to waste everyone else's time asking questions
instead of doing anything useful.

True. Nobody here knows anything that will help you deduce what has
failed without you taking down the wx station, cleaning out the
inevitable corrosion, inspecting the batteries, and making a few
measurements. However, you're in luck here. I've had some experience
with both the WS-1200 and WS-1201-IP.
 
Spare parts. Sorry, no solar cells:
<https://www.ambientweather.com/amwewswestre1.html>
The WS-1200 uses rechargeable alkaline batteries.
<https://www.ambientweather.com/amws1000batt.html>
Rechargeable alkaline batteries are only a little better than junk.
They cannot be recharged to 100% of original capacity and are only
good for a limited number of partial recharges. It doesn't take much
to kill them:
<https://en.wikipedia.org/wiki/Rechargeable_alkaline_battery>
The capacity of a recharged alkaline battery declines
with number of recharges, until it becomes unusable
after typically about ten cycles.
So, every time you run the weather station batteries down to zero
(such as after a cloudy winter), you kill one of the 9 lives of this
cat. Ambient is apparently aware of the problem as the newer
WS-1201-IP uses a super capacitor instead of batteries. I suspect you
could replace the 3 AA cells with a super capacitor:
<https://www.ambientweather.com/amws1200ip.html#caption>
Note: The WS-1201-IP replaces the WS-1200-IP. The WS-1200-IP
uses rechargeable batteries that are charged by a solar collector.
The WS-1201-IP uses a super capacitor for energy storage, and
is charged by the solar collector in the day, and
non-rechargeable batteries at night.
I think you'll find that the batteries are dead, your solar cells are
just fine, and you'll either be making a phone call to Ambient to see
if they offer an upgrade to the WS-1201-IP, or buying 3 more
rechargeable alkaline cells.

chases can be fun.

Well, your weather station isn't a low cost unit from Walmart, so it's
not exactly fair to flame the rest of the world for not having THE RIGHT
ANSWER at the tips of their fingers. You haven't said anything about
your electronics knowledge. If you have none, or very little, you might
be out of your league from the start.
Now, do you have a multimeter of any sort? Have you attempted to
measure the unit's charging voltage and/or current? How about measuring
the solar panel's voltage in full sunlight? How about the voltage and
current (if any) it's putting into the charge controller?
Knowing that information can tell you whether your problem lies with the
batteries, the solar panel or the charge controller. Chances are that a
schematic is not available for your station. You might send an email to
the manufacturer and ask for the schematic. That little piece of paper
could be invaluable for you (of someone who is able to read it and
determine where the problem lies.
Just guessing here, but if the unit uses 3 AA cells, that means that the
solar panel will likely be rated for 6 - 9 volts open circuit, at maybe
50 - 100 mA.
You need to make some voltage and current measurements and report them,
then someone might be able to help you get it going again.

Ummm... thanks for the pedantic correction. By the gooses name, I
just assumed that they vote in Canadian elections. I guess not.
 
I suspect the geese in question might be refugees from Denver:

The problem is that it doesn't quite work the same way south of the
border. In Canada, it's a Canadian citizen, and a Canada Goose. In
the USA, it's an American citizen, but also an American Elk, American
Black Bear, American Alligator, American Bison, American Beaver,
American Otter, American badger, etc. The distinction is perhaps
understandable as the results of our previous presidential election
suggests that some of these animals may have voted.

My weather station uses rechargeable alkaline AAs.
When they failed after several years of use the outdoor unit
continued to function in daylight but not in the dark.
At first I replaced them with Nicads but that didn't work.
I found one place on ebay selling the proper ones and
they are working.
Oddly enough after an extended power outage the
weather station started displaying the symptoms of
failed batteries. A reset of the display unit fixed that.

http://www.corrosionx.com/ has a bunch of anti-rust/corrosion products
of this sort. They speak proudly of their special "polar bonding"
technology, but the safety sheet doesn't mention any ingredients other
than mineral oil and hydrotreated neutral base oil. I haven't tried
this stuff myself.
 
For the non-working surfaces of metal tools, you might want to
consider an old woodworker's trick - wipe them with some pure tung
oil. This is a "drying" oil - it polymerizes on contact with air and
forms a solid film, which (from what I've read) is quite a good
moisture and water-vapor barrier. I don't think it has any specific
oxidation-blocking chemistry (such as Jeff referred to) so it's a good
idea to de-rust the surfaces before you coat with tung oil.
 
I've treated some hand tools by first cleaning up the rust with a
phosphoric acid dip/wipe (rinsing well afterwards) and then wiping on
some tung oil. A thin coat will "dry" (polymerize) within a day or
two, and the coating on those tool surfaces has held up well in
storage.
 
Note that this is pure tung oil I'm referring to - not one of the
commercial "tung oil" varnishes, which often contain little or no tung
oil.

Well, if tung oil works for you, then boiled linseed oil should also
work:
<https://www.popularwoodworking.com/flexner-on-finishing-blog/comparing-linseed-oil-and-tung-oil/>
I haven't tried either.
 
If you can tolerate something that coats the surface and hardens in
place, then any of the conformal PCB coating sprays (acrylic,
urethane, wax, etc) should work. Some have UV tracers built in so you
can see if you missed anything.
 
Anything that blocks moisture, stays in place, doesn't wash away, and
doesn't feed the fungus, should work. For me, that's common
automotive grease, especially the types intended for marine use, which
needs to be waterproof.

Been using Boiled Linseed oil for years in automotive rustproofing. It
dries after a bit of smelly period. Also trying Fluidfilm for rustproofing.
Kinda stays moist. lanolin. Long term results not in yet.

The only thing I knew for sure was minium (lead oxyde), an orange liquid.
And then a layer of painting of your choice for aspect.
But I'm not sure tu use of minium is allowed today due to lead.
It was greatly efficient;

I never see it. Best place I found to get it is Zoro, their discount kicks in low, maybe 6 cans or whatever, or was that free shipping ? I got LPS2 there, I was specifically looking for 2 so that is what I got and I didn't "go shopping". I don't know if they have 3 or 1.
 
I don't like their new cans though. The old ones you used to be able to throttle. Now it gushes out and shoots across the room. (if you got the right tube on it, not supplied) And now I lost my syringe somewhere and I no longer know any diabetics. I work on vintage audio and sometimes you have to clean the tuning cap, but only where the contacts are, not all over. If it gets all over the plates it doesn't matter right now because it is electrically inert. But the dust it may attract maybe not, then it throws off the alignment and will continue to do so.
 
Same with using it on pots, no matter what you don't want that stuff dripping out of it. In the aerospace industry, which uses it, dripping is sometimes good. And the smell is not going anywhere for months. The smell, well it is not worse than WD-40 but it lasts longer. Some people use WD-40 but I won't. It is not the worst but as long as I can get LPS I'll use that.

>And what sells to the knuckle dragging morons is WD-40.
 
What I would like to see is some residue free plastic friendly solvent. I was getting this stuff called Ideal locally. By the smell it is alcohol based, but it works well and wrecks nothing.
 
But of course just like everything I like or want in this world the discontinued it. Grr. Really, you don't have time to read the list.

When I want syringes I just go to the drug store and ask. In WA state
this is not illegal. Sometimes I get 'em with needles when I need
really pinpoint application. I had a diabetic cat and would buy the
insulin and syringes without a prescription.

Rust is caused by oxygen and an electrolyte, which is usually water.
 
To keep oxygen and water away from the metal, cover the bare metal
surfaces with something so that the oxygen and water do not come into
contact with the metal. On a tool where the bare metal surfaces need
to stay bare, paint will not work. A layer of oil is often a good
option. Oil evaporates slowly, clings well to the metal and is
relatively easy to wipe off before use.
 
With metal objects that are kept at outdoor temperature, condensation
is the main problem (unless you leave it out in the rain). Metal has a
relatively high heat capacity, so when the weather changes from cold
and dry to warm and humid, the metal stays cold for a while, causing
condensation. If you can keep your tool slightly warmer than the
outside air, you will greatly reduce condensation and therefore
rusting. You don't need climate control. You only need to keep it
somewhat warm.

If you can wire-brush the loose rust, an application of 'cold galvanize' paint (commonly
used for wire fences) will usually work. Keep it all clear of the aperture of the
receiver, though, JUST paint the metal dish.
