Turn Signal Flasher wiring question

Post by Ten4321 » Sat Oct 08, 2011 9:41 pm



I'm putting together a GL1000 that I bought in pieces. How does the Turn Signal Flasher connect to the wiring harness? The Flasher only has two wire inputs but there are three wires coming from the wiring harness. Also, what do the two wires below the black box connect to. Its not the left side horn those wires are lower.

I don't know if people noticed but my original post included a picture that shows what I'm talking about. I need to know how to wire the Turn Signal Flasher because it has two inputs but there are three wires coming from the wiring harness. If someone with a 79 Gl1000 could please look at their bike and tell me how to wire it I would be greatly appreciated. I have a digital copy of a factory service manual and the resolution on the wiring diagram isn't good enough to see the color code for each wire.

Thanks

I do not have a '79, but looking at the service manual, it shows three wires;

Dark Green, Gray, and Green/White

I suspect you have a relay from a 1975-1977, as those were two wire relays and the 1978 and 1979 were three wire.

The colors on the turn signal relay buzzer are different as well, on your 1979 they are Red/Brown, Gray, and Green/White.

I have no idea of the two mystery wires, let us know the color code and I will see if I can figure it out.

I have a 78 and was wondering which wires you used to plug in. I have 3 wires (green, green and yellow, and brown) bundled up to the relay. I can hear and feel the click of the relay with the green, but my signals dont light up inless I attach the green and yellow. They dont flash either.

According to my diagram, the third wire (green) is only used on German/French market models and, certainly, on my UK bike, the green wire is not connected to anything.

Correct, my 78 has had a 2 prong flasher since day 1.

Thank you. I was wrong on the green/yellow wire its actually green and white. I must have something else going on. I tried reversing the wires on the relay, and they didn't flash.

Do you know if the flasher is in fact good ?

Im fairly certain the relay is good. I hooked it directly to the battery and I can feel it click. When I plug in the green wire it clicks but does not light.
