98 Electrical problem

[Jud]

Hi I have a 98GTP all of a sudden the car seems to have electrical problems like starting fine but after driving a little will die. if you tried to start right then then it wouldn't start be give it a hour & then it would start only to die a mile down the road. I ended up replacing the battery. (Battery tested Bad). Now the car starts but I have a battery light that shows up & my Computer console does not even come on. Does this sound Like a alternator problem, Ground or some other electrical problem. Oh one note to point out I was backed into (pass front door) right before these things started happening. any thoughts would be helpful

Thanks Justin

After starting how long can you drive before it stalls? Any impact damage around the front passenger fender area? Maybe a bad ground. With car in idle check the voltage across the battery negative and positive terminals with a DMM. Voltages will vary but post the results. 13.5 volts - 14.5 volts would indicate the alternator is probably OK but the light would point to the alternator or a monitoring problem via the PCM module. Or you can get the alternator tested for free at places like Autozone.

Thanks for your reply. I have checked the ground & it seems fine. Now on to the altenator.
