One of the 2 parallel 7812's is heating up. It seems like doesn't matter what regulator is there. The regulator in that spot will heat up while the other one doesn't. That doesn't make sense to me. If they are in parallel how is only 1 heating up?
I'm sure u could've guessed but the one that wasn't heating up was dead. Now they both heat up. Very rapidly tho. Like 160f before the switching has even started. Is that normal?
I wouldn't expect them to heat that quickly. Are all of the driver ICs new?
Are any heating up?
Do you have drive from each of the driver ICs?
