Looking for some advice on alternators. My 03 7.3 PSD has now consumed 3 alternators in just over two years and 44k miles. The truck is stock except for two small stereo amps, ( it ate two alternators before these amps were installed so I'm left to assume they are not the problem. Any advice? This alternator is the first I have to pay for and install myself. I really don't want this to be a yearly holiday, Alternator Replacement Frustration Day. High Output maybe?? Thanks in advance everyone!

 

Sounds like a voltage regulator type problem. I just replaced my first alternator at 131000 miles and 10 years of use, and only because the bearings on the old alternator blew out the back of it. I would look towards a voltage problem, not an alternator problem. And if this is the third one in as many years, I would say the dealer only fixed the resulting problem, not the source. There should be some accountability on their part as the source of the alternators failing was not fixed.

 

How many miles on it??

 

Coming up on 45000 shortly. Thanks for the advice!
