I am still having a problem with my voltage dropping all of a sudden causing the car to stutter and want to quit whenever I turn on the headlights, push the brake pedal, put the car in gear. It usaully recovers in a second or so.

I checked the battery ground to frame cable, chassis to engine ground strap, and the starter cables and everything checks out fine.

The car has been sitting in the garage for about 3 weeks now and when I went outside today to start the car the battery was completely dead.

I switched batterys with my buddy to see if the battery was the problem but it wasn't as the dropping voltage problem still occured.

I don't think it is a shorting problem because I've checked everywhere and this problem first occurred while driving on a flat highway.

My uncle did tell me that it could be diodes or something in the alternator causing problems, could all this be fixed with a new alternator?

 

I would say that either your diodes, or internal voltage regulator is/did going bad. Whenever your voltage regulator goes bad you witness spikes in the voltage and drops... and it will drain your battery once it goes bad, bc if your regulator is not working then your battery is basically running everything and bypasses the alternator, bc the alternator is not pulling a load like it needs to in order to function properly. I hope that helps

I FINALLY FOUND THE PROBLEM! It was a bad ground wire from the ECM.
