CL 77 Wiring

[Raceman]

I recently acquired a CL77 that had entire harness removed. Previous owner said it had an electrical problem, the headlight didn't work(Yes the bulb is ok). I checked the continuity on all the wires in the harness and decided to use it. I'm having problems in the headlight bucket such as the green wire from the main harness has a double female connector and is supposed to connect to the green wire into the headlight switch,which is another double female connector. I have power at 4 of the 5 posts on the main switch, the green is dead. I wired up another switch, same thing. Last, the green wire on the headlight grounds to the headlight rim and then is supposed to ground to the speedo. Where does it connect to the speedo? These are probably simple issues, but they have me stymied. Any help appreciated.

There isn't actually a ground wire in the main harness, Honda apparently see the need for one in those days. The bulb socket for the speedometer dash light has two wires. The center one powers the bulb(green with white tag) and the other one(green ) plugs into the headlight wires for grounding.The black/white tag wire is the feed from the main switch(also feeds the neutral light socket). Power out to the tail light and dash light is green. Headlight power to the dimmer switch comes from the brown wire. The pink and yellow wires are alternator leads and are combined, when the lights are on, for more generator output. The headlight switch is off in the center. Turned counter clockwise it should have power at the green wire only. Turned clockwise it should have power at the green wire and the brown wire. There should continuity between the pink and yellow wires with the switch in the headlights on (clockwise) position.

Found two problems. The dimmer switch is bad and the headlight wasn't getting ground. Presently all working with dimmer switch offline.

Dimmer switch probably is not bad, just gunked up inside with 8,000 year old corrosion and grease. Taking it apart and cleaning it is easy. Getting it back together, with that damn ball bearing effing with you the whole way, is not.

Took the dimmer switch apart and cleaned the contacts, it works. The ball bearing wasn't the problem, the thrux capacitor for the turbo encabulator kept getting in the way. With the exception of having instrument lights, I now have a functioning harness. A new harness from Thailand ?????is coming. I hope it's not junk.
