I own a 1991 Chevrolet Cavalier RS 4 Door. It is a 6 cylinder engine, and the mileage is 190373. I was wondering if you can help me. My cars Battery Light will come on if the engine is up or over 4000 RPM. And my taillights will stay on all the time even if the pedal is not depressed. The mechanic I took it to says its a ground, but my dad tells me that it's my brake light switch thats keeping the brake lights on all the time. I dont know a thing on how to fix this so I came to you guys. Can you help me?

Ok, I installed the new brake light switch and the taillights are working great now. But is there any different reasons such as grounds that are causing the car to kill itself all the time?

The mechanic I had look at it said to put a wire on a bolt on the engine block and ground it to the body of the car. Could that solve it probably?
P.S sorry to bother you all the time.

If you mean warning lights, no nothing else is staying on. I just don't understand. I'd connect it with another car and it would run like a dream. But once I take off the cables off of my car, it will run for a few seconds, start struggling and then poof, it's dead again.

Where does the neg cable go, have you checked that yet, make sure it is still on the eng and not broken or corroded, if you have to jump it again, try just removing the neg cable and see if it dies again

Put a fuse in it and see what happens, my guess is someone may have had a problem with the horn and pulled the fuse, maybe it kept blowing the fuse, any luck with your other issue? I would stick to that right now, get ya on the road first then we can tackle the horn

Well I went to the garage to check the negative terminal cable, and I wasn't able to see underneath the car due to snow. I was able to get a booster pack and fire up the car. I went to start the car up and it worked fine but the absolute minute I took the negative booster off, the car died. I hope that was enough info for now until I can get more

Hi. Me again, I realized already that my alternator was burnt out, but that scrap guy at the garage says that there might be a problem with the ignition system that may cause the alternator to burn out. Could he be right?
