Hey Jim, I was going through your charging system by dummies list and when I jumped out the regulator the bike started working perfectly, 14.6 volts at 3k rpm at the battery. The battery voltage is 13.18 not running, 13.08 key on, and 12.79 at idle 1,300rpm (with the apparently faulty regulator) still plugged in. With the regulator jumped out at about 1,300 rpm it reads 12.9/13 volts at the battery. So as far as I can tell the regulator/rectifier is bad? Ground to any part of the frame, handlebars and engine comes back with zero resistance.
