Wiring issues for rear and front turn signals

Post by Rc67 »



So,

I am in the process of getting my 1980 GL1100 finished and buttoned up, but I've been tackling a wiring issue on the bike. every time I connect the turn signals and click the switch, the lights will come on, but will not blink. at first, I assumed it was a bad relay and got a replacement, but the same thing happened. I wrote about this in one of my other topics, and one of the members said to check the ground.

I followed their advice and traced the wires and saw that the ground wire, had gunk all over it, so I sprayed it with carb cleaner, as I could not get to it and unscrew it for a better cleaning. it looks clean, but I'm still getting the same response from the turn signals.

my rear sub-wire harness was kind of beat to hell, but even if I connect just the front lights, I get the same response...Not sure where to look now?

Won't blink unless both front and rear lights are working.

Some of the 1100 turn signal fixtures have three wires, ground, one for the bright filament, and another for the "Running Light" filament (dim), if you accidentally connect the "dim" filament to the turn signals won't blink either.

If that is an OEM flasher relay they won't work on low voltage. It's not unusual to have to rev the engine when at a stop with the turn signal on to get them to flash. You can replace it with an automotive electronic flasher for about $10 and it will work much better. Since the lights do come on it's not a ground problem.

Hey Dave0430, do you have any particular brand I can look at?

Stant, I think, it's all I can think of at the moment. All parts stores have them, just a simple 2 pin electronic flasher. You will leave the green wire off.

I have one more question, just to make sure I'm not missing anything. I was looking at the wiring diagram, for my 1980 GL1100I, and i found one ground point near the ignition coils, so I cleaned that one. I believe there is another ground point, but the diagram really doesn't point me in the right direction. I believe it's somewhere near the rear of the bike? I just want to make sure none of my grounds are cruddy...

The only other ground is the battery ground point behind the triangle engine mount on the left rear.

Dave0430,

Getting that electronic signal relay did the trick...thanks

One last question, my saddlebags only have two wires, and my lights will blink but not stay on as running lights. There is only two wires ground and the positive,but I’ve seen some bikes where their saddlebags had running rear lights. Is there any way to wire it where I can get them to be on while bike is running?

You would have to change the bulb sockets to dual contact and run another wire to them.
