Can I test my alternator off the car?
I have a choice of 2 units and would like to test. My local parts store says they cant test it out of the car, only when installed. Thanks |

Called my FLAPS who assured me they could test an externally regulated alternator. Drove a half hour to town and handed it to them. The hooked it up to their test equipment. NOPE - couldn't test it out of the car. Drove 30 minutes back home with nothing to show for it. I just went through the bench testing procedures outlined in the factory manual with a multimeter. Those test all the components (diodes, windings, etc.) so my assumption is that if all the parts test ok, then it should work. We'll see...
