Its kills alternater, its charges good until I

Sounds to me like you have a grounding problem Have you had the transmission loose lately because there is 3 ground wires on one of the bolts if it is not tight you endure the systems taqht you are speaking of. Check it before you do anything else and it wont cost you a dime. I was told the alternator went bad. I had to replace it again and it isnt the problem. Check Your Ground
