[QUOTE="Dub7sonoma, post: 8347762, member: 649968"] Your alternator should be a case 130d which even know its rated at 110 amps when warm they usually test around 70 amps. At idle warm they usually only have an output of 25-40 amps which is terrible. I would suggest getting a add244 case alt. They come factory on newer GM full size vehicles and up to 160 amps. It will be a direct bolt on and all it will require is sometimes a slightly longer serpentine belt. Its a larger case alternator that will put out 2-3 time more than yours at idle and probably twice as much wide open. I would hit up the local junk yards and get you one. I have paid $20-$30 for everyone I have bought and its a huge upgrade over the small case alt you have and would probably solve your voltage drop. But I would also check to voltage like I was explaining earlier [/QUOTE]
