anyways I got my 88 GT today, I love it(came with intake, MAC headers, H-pipe and tail pipe, UDPs). the 5.0
anyays the car developed an idling issue today...so first I checked the battery voltage and it would not go over 12.5-.6v while idling, would steadily drop as the car sat(only rose when pressing the gas), when the a/c is tunred on the car basically dies...so that led me to think alternator is bad...I did a search on here and found that many times using UDPs and the weak 75amp stock alternator don't make a good combo. so this led me to get a new alternator with a stock pulley. I got a new alternator, and instead of using the alt underdrive puley, I used the stock alt pulley(also got the new correct belt size). so now I'm running stock alt pulley, ud crank pulley, ud wp pulley and stock ac pulley and STILL the alternator WON'T recharge the battery(slowly dies) and the car's idle surges and fluctutes.
I searched again and found some more info and was wondering:
1. should I just go back to all stock crank and WP pullies??
2. is there a fuse or a fusinle link that could be blown between the alternator and battery??
any help would be great, I can't wait to get this car fully running!
