Hi all. As I am a nubie to all things motorcycle, I have nothing but gratitude and respect for you SOHC devotees.
Okay, I am learning how to use a multimeter to get a bad wiring system going on a 1974 bc750. The first problem I found was the main green ground wire was melted as was the one coming from the front of the bike when it splits into 2 or 3 wires--I think it turned to three, however one was unused. Anyway they are were fried. I checked the voltage on my batt--good at 12 v. Then the two red wires which exit the selenoid (sp?) are both good and "hot" at 12v. But one of the wires (the solid red one) goes to nothing(just dangles hot) while the red and white one has been rigged up to split off, one goes to the rectifyer and the other all the way to the fuse box.
My connection starts to fail here...the bottom fuse (5a) (main?) has power (12v)at all four points (entry adn exit) the other two get no reading. Then up where the switch or connecter that connects to the ignition I have power except the brown adn maybe another. When I turn the key nothing happens, no elect. AT ALL> Question, the green that returns from the front of the bike, can I just ground that anywhere, or does it need to be grounded at the bottom of the rectifyer? The voltage regulator ground, and the rectifier ground both were split off the green coming from the front of bike, which is exactly where my melting occurred.
I also didn't get any volts comming out of the yellow and red on the selenoid, is this normal?
I can send pics
Thanks in advance guys!
