I'll have the Fluke with me when I go this weekend, but from post 15: "The last time I checked it, I think the volts were ~14-ish at idle (when both cyls were firing) and, yes, the lights brightened when the engine's revved. It's ALWAYS done that (I've owned the bike since '75)."
Yes Sir Patience and cooperation lets see if we cant find it
lets take it from there .( Across battery measurement ) ..it is simple and quick to do .. and we then go on to other steps.If it checks out
Systematically trying to find something strange
if 14.4 fine it is checked I can be wrong not the first time ..
Then it will be to check at the fork in the cable splitting into 2 before entering coils
What voltage there
And at points how much voltage is there
Systematically step vise.
