Or worse. I find many times they go short with no visible evidence at
all.

I was pushing the boss for a thermal imaging camera for this very
purpose, just apply power till things get warm enough in the right spots
to tell what is shorted.

I thought I had put forward a very good argument for saving time during
repairs that are relatively rare where we were, but he still sadly
didn't go for it... Oh well, I tried.

I use a IR Laser guided Temp probe. that works nicely.
