Topic: CB900F M Unit blue wiring

[LukeN74]

Does anyone have an actual finished diagram of the 81/82 CB900f with an m unit? I’m almost complete (I think) but my solenoid seems to want a ground and not the power from the “start” output on the m unit. Not sure how to convert it or if it’s even correctly setup that way. If I ground the green to the frame I get the m unit blinking, and otherwise just regular setup I get no response when hooking the start output to the red/white wire from the rectifier to the solenoid. What fires the starter is running a ground to the empty terminal on the solenoid (not the red/white, not the 12v sensing black, and not the green “ground.” Ignition on, they all seem to get 12v as well not sure if that’s normal.

Thanks

That would be great. I understand I’m on the SOHC forum but I’m reaching for strands. I’ve seen finished bikes but cannot find a diagram for the life of me and pulling my hair out every night working on the thing. Thank you. In the meantime I will keep searching.

Cheers!
