914 charging problems
 

I think I already know the answer but before I go through the work to replace the alternator I would like to confirm my findings.

I have gone through the troubleshooting steps from the tech info and these are the results.

When I apply battery to DF the alternator starts putting out 13.8v and remains there when I remove the battery. If I short D+ and DF the Alt. light remains on. Last there is a 6v difference between B+ and D+ (not sure that means much but if I read right the difference should be 0v).

Oh yea I have not replaced the bulb for the Alt. light but that doesn't mean someone else hasn't.

PS How do you tell the wattage the bulb for the Alt. light

Dont run the engine with the battery disconnected. You risk frying the alternator.

Thanks I jumpered the pos side of the battery to DF. Sometimes my fingers get in the way of my brain :) I meant to say I applied 12v(battery) to the DF side of the alternator in my first posting.
