I am trying to determine whether the alternator was damaged by incident or if some other component of the system is causing the problem. I used a voltmeter to perform a diode test and it appears that the diodes were damaged. This is the first time I have worked with a potentially damaged alternator and I am unsure of my testing skills and techniques. I tried to have the alternator tested at two auto parts stores, but the alternator did not fit on their machines correctly and they couldn't run the test.
I purchased a used alternator from a recycler and replaced the voltage regulator on it. It passed the diode test that the original alternator failed. Are there any other tests that I can run on the used alternator before installing it in the car? I will try some other parts stores to see if they can test the alternator, but the machines I've seen appear similar and I am not sure I will be able to find someone to test it.
have the same problem?
