Alternator on my 1981 GMC / 250 I-6 is barely charging. The battery stays charged but it is at 12 VDC with the motor off, and only goes to 12.5 Volts with the motor running.
The power steering pump had leaked on the alternator some and I took care of that. I have TWO questions...
Would it be trouble to disassemble the alternator and clean it?
Is there a decent drawing or diagram of the alternator somewhere?
