Why is check engine and battery lights on? replaced bat and alternator

Question

Well, I have a 98 Dodge Neon. The battery light came on, and of course shortly after the battery died, took it to the alternator shop where they tested it free, and said alternator was properly charging (battery had acid coming out of it). Well, got a new battery and the battery went dead, would work if we charged it for only a little while, so we replaced the alternator:

now the alternator has been replaced, and .this time the battery and check engine light both came on after charging the battery. I need the car for medical appointments 54 mi. away. Any suggestions?

Answer 1

the voltage regulator for that car is in the computer it is probably faulty. by the way durlast is from autozone not advanced. advanced usually has good alternators. my guess is computer

Answer 2

Might be the computer again. There may be something tripping it up. Get it checked out again. As far as your battery light goes if your battery and alternator is new then you shouldn't have a problem. That is why it leads me back to your car's computer module. It's bringing up faulty warning lights.

Answer 3

I'd suggest taking it to a reputable repair facility and have the charging and starting system checked out. Most shops charge @ 30 dollars for this service. Your rebuilt duralast alternator could be bad, as I have seen it many times.
