These always-available-with-instant-playback devices can make re-assembly easier, too! [blush]

Finished up today. I routed the FARS solar panel to the ISS and used it in place of the smaller one. That should keep it topped up on overcast days and long winter nights.

Update: I got repeated low battery notifications the last couple of days. Today, the ISS stopped transmitting to the console. I swapped wires back to the ISS solar panel instead of the FARS panel, and it started charging again and the console came back. I never bothered to check the output voltage of the two panels, and assumed the larger was likely higher.

I guess I ought to go check. But it is 92° out there, so I'll wait until after dark when it is cooler to check the solar panel output voltage.  [sweat2]

Dear Steve and WeatherCatters with the most toys, . . . . . . .  [biggrin]

 [wink] . . . . . Hold it right there!  I see your problem! . . . . . . .  What you need is to spend some of those economic stimulus bucks on a super-deluxe multimeter like this! . . .

That way, the next time you have the slightest itch to measure a voltage, you'll immediately hop to it in order to play with your new toy!! . . . .  lol(1)

Cheers, Edouard  [cheers1]

I'm retired on fixed income. Stimulus money paid the bills. ;)

I already have two very good multimeters: my Dad's iconic 1960s Simpson 260 analog meter. And a 1980s Beckman DM45 (same accuracy and features as the Fluke 75 - today's Fluke 175.) My employer's parent company, Emerson Electric, at the time owned Beckman Industries, and was Fluke's main competitor along with BK. So I got it at a discounted price.

The ISS solar panel's output was 1.67V when I measured it, and the FARS solar panel's output was 1.86V, but was very inconsistent. It either has bad cells or a broken connection. Further investigation will follow. I suspect the larger panel has more wattage capability, but no easy way to check that.

Dear Steve and WeatherCat "economists" who stroll down memory lane,

[wink] . . . . Bummer dude!!  I didn't realize that inflation was now so bad that it has even spread to model numbers! . . . . . .  lol(1)

Seriously, thanks for sharing that little historical snippet of the electrical/electronics industry and glad that your station is back to purrin' like a kitten! . . .  [cat]
