To start, I'll say I don't have the "proper tools" the manual wants you to have to test the alternator, the best I've got is a multi-meter that reads AC, DC, and resistance. I've gone through and checked what I can on the alternator itself: the resistance. the field coil reads about 7 ohms, and all the stator whatevers read about 0.4-0.7. That's all up to spec as far as I'm aware. After checking the actual hardware, I decided to see if I could get a reading directly from the alternator while it's running. I set my multi-meter to ac, and starting probing the connector. I'm not exactly sure which thing I should be checking, theoretically they should all give a reading of some kind. And they do. 0.2 volts AC That can't be right, right? This is supposed to charge the battery, how in the world is that enough. Maybe I'm reading it wrong, maybe it's impossible to actually get a reading directly from the alternator. If all of that is correct and how it should be, the only other culprit for it not charging is the regulator/rectifier.
