Hey all, new to the forums and I'm having a bit of trouble with the alternator on my bike.
My bike is a 1980 CB 750.
The stator's yellow wires all test good, with ~.5 ohms between them all, none to ground. The issue is with the white/black wires. They show a wide range of Ohms between the two when on the bike, which from what I've read so far, is bad. However, the white/black wires test fine when the stator is off the bike. The wires start to show Ohms when the brushes start getting depressed. They also show Ohms if I press the brushes down with my fingers. I initially thought the rotor was bad, but the rotor tests good with I think ~.5 ohms between rings of copper. No wires show a short to ground.
Any ideas or other things to try?
