my voltage drops when I turn my headlights on and If I also turn my heat on high the voltage drops down so low it almost stalls the car when I come to a stop. If anyone has any input it would be greatly appreciated!!

you dont have UD pullies do you?

That's normal. Welcome to the world of the undercharged foxbody. I recommend doing the 3g alt conversion to take care of that.

No I dont have under drive pullies!

thats weird because i have the stock alternator and i have underdrives

i can have the heat on and the lights and i dont notice any difference in rpm.

i was thinking of getting ud pullies anyway so maybe I will try that. Then later on down the road I may also do the 3g!! Thanks guys

You do realize installing underdrives will make it worse right?

I have done the complete upgrade from alt. to new wires and I still have low voltage at idle. It helped a great deal and my battery does not die to often, but not completely.

No I didn't know that it would make it worse. maybe I will do the3g install then do the ud pullies

i upgraded to a 200 amp 1 wire alternator, moved the battery back into the rear of my hatch, and installed 2 600 cold cranking amp high output batteries in parralel. That more than took care of my charging issue, have not had any problems since.
