I made this to test my friends Subaru Impreza Alternator. It has a smart alternator which can sometimes not charge the battery. Next video will hopefully show the testing of the alternator. Just waiting for back bearings to arrive. The ECU can sometimes send a no charge signal. If you cut the C wire I think it goes back to an normal alternator charging at 14.2 volt. Check before doing that. I might be wrong.
