Re: rebuild alternator

Ok, with the internal reg alt. you can test them. On the back side there is a "D" shaped hole. Put a voltmeter on the battery, start the engine, insert a small screwdriver into the hole and apply a little pressure on the internal tab. Watch the voltmeter, if the voltmeter goes up, only the volt reg is NG. I believe the regs are all the same.
