    Hi. I have a 2003 chevy express van with the 5.3 engine. The alternator keeps overheating. I’ve changed it twice but the same thing happens. I’m getting very high voltage from the tan wire that’s inside the alternator wire harness (50vdc). Please help if anyone can, it will be greatly appreciated!
