This isn't a Celica problem, but its a toyota problem and I trust 91ST's advice so I hope U read this lol.
My Supra will not hold a charge and the battery will die within a week or so. My Q is...
The insulator cap on the new alternator is broken(I did it lol).
will this cause a short while the car is not running and just sitting?
I've been trying to find the problem because I cant drive it anywhere without worrying that the battery will be dead when I get back in it to go home.(I've had to tow it twice now).
Any suggestions?

Well a guy on the supra forum told me xactly what i didn't wanna hear so I got alot of work to do to the damn car before I can really start on the celica. One day off a week with 2 kids and a wife. There just aint enuff hours in the day. LOL
