Low Voltage
There is not enough voltage being generated. The headlight is dim in idle, at high rpms and head light brightens. Motor runs fine, but the batteri is not being charged.
I don't know which part to replace, there is the generator, stator, rectifier, regulator-Voltage. The costs ranges from $135.00 to $615.00 fora part.
I would like to fix it myself and save on labor.
How do I zero in on the part causing the problem?

RE: Low Voltage
Unhook the stator, and when the bike is running you should be able to put a voltmeter on it and check for voltage, it should be equal to the voltage of the battery. If that isn't your problem, then I would say your battery isn't holding a charge. If at idle the lights are dim, and when you rev the engine the lights brighten back up that should mean your stator is working, but your battery is bad.

RE: Low Voltage
It sounds to me like you're using wood screws to ground electrical accessories to plastic trim. No, but seriously, how many volts are you getting? Take the battery to Advance Auto and they will be able to load test it for you. That's going to give you a good starting point to work from.

RE: Low Voltage
+1 When batteries get old they will show good voltage, but will not have the amperage to live under load. You could also have a dead cell in the batt. You could also have a liquid ground, When batt juice condenses, leaks, whatever onto the tray/clamp and makes another ground. All you need to do is get some baking soda mix it with some water like a paste and clean the batt area. I just went through this with my buddies 65 Falcon.
