My '80 LM II won't charge. Where should I look next, after checking my rotor, changing the diode plate, changing the voltage regulator with new items? I have continuity in the 3 yellow wires from the stator, I have a good charging light filiment, good brushes and springs, but I can't find any voltage at the brush from the wire that comes from the voltage regulator although there's continuity. All my connections seem real nice, clean, slightly lubed, and with re-tensioned spade connectors. The battery, when I last started the machine 2 nights ago, had ~12.2 Volts only. Wouldn't that be enough in order to get the required voltage up to the slip ring? I may just run all new wires throughout the charging system next to try and get charging. I revved it up to 6 grand, and nothing was going back to the battery. The ignition was just running off the battery. Woe is me, I'm supposed to blow town on the bike Friday morning! John Z or anybody with Bosch alternator smarts, could you tell me where to look next? Thanks in advance any/everybody!
