GL1000 Wiring

Postby blackbeauty » Wed Jan 11, 2012 8:11 pm



Hi all, I am new to this so please bear with me. I bought a 1977 1000 from a person this fall and have started the winter tear down and paint. When I was taking panels off I noticed that some wiring had been cut and spliced together. The problem I have is to start thee bike I had to touch 2 wires together and the horn doesnt work and the light for nutral stays on. I am looking for a diagram for the wiring to help me figure out what was discarded in the first place.

Any help would be great. :D

Click on the "Manuals" link at the top of the page, and select GL1000 for your model year. You'll see a downloadable file called "Honda Goldwing GL1000 1975-1977 Color Schematic" that should be what you're looking for.

By the way,if the wires that were spliced together and they are 3 yellow wires...that's OK,,,It's a modification for the charging system and has been approved by the owners of all who have had charging problems on the 1000,1100 and 1200
The neutral light staying on is usually a contaminated neutral switch attached to the block on the front right lower side or a pinched/chafed wire near the radiator.
Touching 2 wires to start it....Well where are the wires and what colors are they?
This bike is familiar to many of us...We can help to get it right. :)

Neutral light staying on can also be a failed diode in the 4 diode block under the left shelter cover. The dirty neutral switch is the most common solution, but for me it was the easier diode replacement. One that glows dull is often a light leak though the cluster caused by the light staying on all the time before the switch was replaced and causing a melt through the light divider.

In the wiring the plug ins on the back of the fake tank are what I am having issues with. Mine dont have the black box that they are conected to.

Trying to figure out my wiring. I have the diagram for wiring but I am trying to figure out what the black box on the picture I posted is because my bike doesnt have that.

That black box is the reserve lighting unit. It was Honda's idea to keep lighting functional as bulbs burned out. Only they do not age well, and after 35 years of exposure, more often than not they cause lighting issues. For me, I had a sometimes functional, sometimes not, brake light. Jumpering over the reserve lighting unit made my bike reliable again.

So it looks like your PO already did that. Nice upgrade if you ask me.
