electrical issues

Postby harrisondr » Sun Aug 29, 2010 11:59 pm



I just purchased an 81 interstate. I am replacing fluids, tires, fuel lines, etc. I know the previous owner did some unorthodox wiring in order to make the headlight work. The electrical system functions as follows - 1. With the key set to start, both the fan and the headlight are on. 2. Hi-Lo beam does not function (High beam is always on). 3. The headlight works until the right blinker is turned on, then the blinker works but the headlight goes out. The headlight work the rest of the time. I'd appreciate any ideas you have.

You can download the full-size version of that diagram in the "Manuals" section above.

That said, I think you have some serious troubleshooting ahead of you. It almost sounds like some things have been hooked up incorrectly. You're going to have to trace individual circuits - I'd start with the headlight circuits - back from the headlight to the ignition switch/fuse block.

I don't have the plug/pigtail to connect my Honda fairing, so I had to trace the plug to the lights in the fairing. here is what I have:
1 2 3
4 5 6
7 8 9
1: left turn tail (white)
2: right turn blinker (blue)
3: radio power
4: left turn blinker (orange)
5: headlight low beam
6: clock power and presets
7: right turn tail (white)
8: headlight high beam (blue)
9: unknown, not connected
This is looking at the fairing plug. Let us know what you find?

I had the same issue for a moment when I was removing the radio from the lower left fairing. I was installing (shoehorn) a radio/mp3 player in the upper right pocket. There was a ground on a stud that mounted the old Clarion II radio that I had left disconnected in my haste to wire the new radio. With out that ground connection (Green wire w/ ring lug) my lights acted just as you described. When I reconnected that ground wire to the stud all systems returned to normal. Apparently everything in the (Hondaline) faring gets it's ground from the chassis rather than the wire harrness.

Thanks to all for great starting ideas. I'm looking forward to the weekend's adventure.

I removed the false tank to inspect the electrical system. I noticed some black substance oozing from a small metal box with the letters "OKI" stamped inside a diamond on the side. This black stuff has dripped down on to the frame. The box is directly forward of the indicator relay unit. Could someone tell me what this is? Could something have melted? Thanks.

These are your igniters - they produce the pulses for the spark plugs. For reasons yet unknown, the potting compound in them fails after a number of years, and melts out as black goo. They're fairly easy to fix with epoxy - have a look at this thread.
