Whats the question? I have a Harley XLH 1100 factory service manual. Let me know what you need. Cheers .

With the battery fully charged and the motorcycle running at idle, you should get 14V at the headlight terminals with headlight disconnected and headlight switch on (if yours has a headlight switch). When you rev the engine, voltage should not vary at all. If you do not get 13.5-14V at the headlight terminals, or if voltage varies more than 1V or exceeds 14.2V, replace the voltage regulator. (They typically only last a few years.)
