I have learned a ton from this site and got a long ways restoring my 97 z28. I hit a snag today though. I have searched for a starting point but keep finding answers that dont fix mine. Among the 1000 things i gotta fix today i changed my serp belt, battery, and altenator. i assumed my dead battery was from the alt not charging and decided to change everything. well i drove the car for 20 min. to have the battery die again. i am assuming that the alt is not charging the batt. Any idea as where to start looking would be a great help. Thanks in advance.

 

Did you check the voltage at back of alternator? Should be around 13v. I think mine is doing the same thing.

 

not yet...i wont have my multi meter till i go back to work tomorrow. i was thinking its gonna be something else though with the new battery and old one doing it. i bet my original alt was good. the car stalled going up the driveway, and it started right back up. i parked it and turned it off. when i tried to restart it did nothing. no clicks or anything. all i could hear after i took the key out was a clicking noise from passenger side dash...maybe that meant something..im not good with the electric part on cars.

 

Next time it won't start go and wiggle the negative wire, mine will do nothing sometimes and i just wiggle it and then it starts. I don't know too much but I'm speaking from experience. I'm pretty sure my nagative cable is bad and corroded and that's why it doesn't start sometimes but I don't know if a bad negative wire can cause it to not charge right. Maybe someone will answer better.

 

If you can make it to a auto parts store they can check it for free

 

figured out the problem right after i started this thread...incase it helps someone else, ill let you all know what a stupid thing i did...when i put in the new battery i also used the felt corrosion pads. they were causing bad connections to the battery. i figured it was a simple mechanical error
