Re: alternator keep dying

I would be checking somewhere else.
Battery, cables, grounds, accessory loads.
The alt is designed to keep the battery charged and to run the accessories.
It is not designed to charge a dead or partially dead battery. If the alt is running at full output for extended periods of time, this could cause it to fail.

Re: alternator keep dying

I was working at an auto parts store and had someone with the same problem, turned out to be the connector on the side had a short in it.
