Hello all,
I am trying to diagnose a charging system issue on my 1980 CB650. The voltage across the battery does not go above 12 V at any engine rpm and I suspect the rotor.
I measured the the white and black leads from the wire block for the rotor/stator and the resistance varied greatly between 4 and 130 ohms. I want to remove the alternator housing so I can measure the resistance more directly to hopefully remove the fluctuations.
If I remove the alternator housing will oil come out? I just changed the oil and I dont want to do it again so soon because of the money. Any advice?
