1977 300D W123 Alternator

Replaced my old alternator with a rebuilt one. After about 300 miles the rebuilt one died. Thinking maybe I received a bad rebuild I replaced it under warranty. The second replacement lasted about 1400 miles and than it died. Am I missing something with this replacement? I can understand one bad rebuild but two seems to be too much.

Why?, Whats strange is doing the same thing and expecting different results. If you just installed your third alternator from same supplier how long do you think this one is going to last? I guess between 300 and 1500 miles. It can be the alternators are crappy or it can be something is wrong with the car that is burning them out.

Next time take the alternator apart and see what wrong with it. Are you replacing the voltage regulator with the alternator if so next time just replace the voltage regulator see if that fixes problem. If so then try to figure out whats wrong causing the voltage regulator to fail.

Then again it's not uncommon to get two bad parts in a row happens all the time and the third alternator my last for years.
