1967 R60/2. When I turn the ignition switch on all the lights work except the headlight. Signals, running light, and tail light work. Is this the way it should be? No power to the headlight at that time. I have six plus volts at the battery when switch is off. When I turn it on voltage drops way down. When I start the bike my meter jumps around at very low numbers.

By looking at these pictures does it look like the brushes are too short? Anything look out of order. I'm getting new batteries in my better meter this weekend. So with luck I can get some good data. I went around the block. Headlight worked when I left but not when I returned.
