which tap did you use, the one thats always hot?

That would explain it reading 100F until you kill the power.

what do you mean allways hot?

i checked the (+) source with a volt meter and it shows 0v when the key is off/out.
with the key on. it shows 12v.


kinda frustrating..... ???

might be getting backfeed from something, DC is a PITA like that sometimes.
