I just bought and installed a new battery and alternator. I thought it would solve my problem, but it didn't. A charging system test showed that the battery was getting enough juice. However, after running the car for about 10 minutes the charge light comes on and the battery obviously quits charging because it will only start 1 or 2 times. My car is sitting in the parking lot dead because I'm stumped. I thought maybe, just maybe it could be something as stupid as a bad fan motor taking up too much power, I thought it could be that because that's about how long it takes for the fan to kick in if its just idling and if I start it up and immediately take off, it kicks on as soon as I pick up speed. Any help or advice is welcome!

 

check the connections on the alternator and make wure they are screwed down and plugged in all the way......and clean the battery clamps...

what year is the car???

 

2000, Yeah, I've checked, re-checked, and re-re-checked they alternator wires and ground. and i've replaced the terminal connections to the battery, both neg and pos.

is the alternator a brand new or rebuilt can you take it off and have it tested? is the ground on the negitive cable good is there small wire from neg cable attacted?

 

if it is an aftermarket alternator new or rebuilt, that is most likely your problem. we deal with this alot at my dealership. the aftermarket electronics are always hit-or-miss whether or not they will last. the fix is always put in the mopar part and you'll be good to go.

 

I'm thinking it is a bad Stator Coil in the alternator or a bad connection. There could be a regulation problem going on here as well.

Most of the time it is usually a bad alternator or connection.
