[QUOTE="03yellow, post: 9395575, member: 19927"] Our alternators are 130 amps! I am underpinning it by 14% A higher amp alt will add more windings to the case... making it hotter. As predicted we are now seeing failures with the start-n-charge alts because they are starting to see some milage. I also predict we will see lots of threads in July with more failures. You got it right when it comes to heat. TOO HOT TO TOUCH is an understatement. The small case does not allow for air to circulate. And its buried in the engine compartment. POOR DESIGN on the case and location. Ive been thru 4 alts so far. They were all cooked inside. and all of them went in the summer. The guy who rebuilt my alt last time showed me the windings... looked like there was a fire inside the case. You can buy an expensive 180amp (with all the best parts LOL) and underdriven it with a larger pulley and it wont help. NOT much! Ive tried all the alts (not the start n charge until the results are in) and nothing will help to put the fire out inside the case. The cure would be to relocate the alt and build a bigger case.
