So too complicated and dangerous to actually look under the shrink wrap or actually use a multimeter. Keep’m dumb.
They shouldn’t call u folks diyers.
Interesting is there are a couple other people in the thread saying the same exact thing as me and to check the voltages but somehow you guys have all latched on me as the bad advice giver. And then there’s those on endless sphere who will say the same. Really it’s pretty standard for figuring if a battery is damaged but we can’t have figuring happening around here it seems.
