1980 GL100I Left Switch Questions

Post by rosco054 » Tue Nov 03, 2015 6:56 pm

I am trying to bring back to life a 1980 GL100I that sat outside for a few years. I have a lot to do. I cleaned the left switch and was screwing it back on the handle bar when I cracked the housing. I decided to replace it with the same model number switch. However, when I received the new switch the wiring was different and there is something on the original switch that is not on the new one. I hope someone has seen this before and can help me.

There is a little white button on the top of the left switch that attaches to two gray wires that are not included in the main wiring. Anyone have an idea what it is?

The gray wires come off the back and eventually hook into two wires that go into the front cowling.

These plugs attach to wires that go into the cowling.

Also the wiring is different on the original switch than the new one. The existing switch has more wires. I think I'll look through some wiring diagrams before I ask those questions, because I also found some connectors that don't have any wires attached at all and a gray one that has been cut. I have no idea where these are supposed to go. Is there a 1980 GL110I wiring diagram on the site?

Thanks in advance for your help.

For wiring diagrams for the 1100 go to manuals at the top of the page. Scroll down on the 1980 page and choose color schematic for either Standard or Interstate model.

That switch is not original - it's been added by a previous owner. As to what it controls, you would have to follow the wires to find out.
