Because of the forum I have successfully, among many other things, rewired my 75 (below) using a posted simplified wiring diagram by Jayal and input from others' posts. It was something I wanted to do for a long time. Recently, I started having arcing issues with the points, replaced them with new OEM points which did not resolve the issue. I decided then that it was time to rewire the bike. It now starts instantly, runs really well and is charging as it should. Replacing the original ignition switch was very helpful, it had high resistance and was causing the voltage to drop and was missing the keyslot anyway, you could use anything to turn it. Replaced the coils with original types, caps and wires, replaced the rectifier with a $20.00 amazon special and the regulator with a VR115. Replaced the original stator & rotor with a newer used spare I had on hand, All new soldered bullet connectors, LED tail and turn signals. Next project is converting turn signals to stop, tail, turn using 1157 LED. On that note, I also replaced the flasher unit to use with the LED turn signal bulbs. Interestingly, it works fine on the battery only but when the bike is running, the activated signal flashes randomly and at different speeds. At first I thought I'd attempt to fix it but have since reconsidered with the thought that this is much more attention getting than just a normal flashing signal. I also ordered and just recieved a "SparkBright" to monitor the charging system. I have not yet installed it as I want to replace the mini speedo with XS instruments and a somewhat customized dash.
