Thanks man. I just ordered one.

Thanks.. I pulled mine out after a long day of being stranded all over town. And the regulator looks super bad. Cool.. hopefully that fixes the problem. I did here if the battery light on the dashboard doesn’t work then your alternator won’t work either. Have you ever come across that?

[@FLG13]

I'm sure it will! Yes the battery light is the exciter for the alt to start charging. That being said, even with a bad bulb most of the time a Rev to about the 3k mark will start it charging as it will self excite.

@@FLG13 Later e30s had a resistor in series with the bulb so that even if the bulb was open circuit, it would start to charge. I forget what year this was added.

what about reman alternators by Bosch? I'm assuming the quality should be decent although some say its po-po

[@FLG13]

Depends, lately it seems like everyone is going with the cheapest options for manufacturing or rebuilding
