Blinker Issues

LikeyMeYommy · Nov 7, 2022

Hello all! Currently sorting through several things with the 79 650SF. Amongst them I have some blinker issues. Right side lights up but it does not blink. Left side does not light up at all and obviously does not blink (ha!). Checked and all the bulbs are good. I had read in another thread that you really have to watch which wattage bulbs you are using (even for incandescent). Could this be an issue? Any other suggestions where to start troubleshooting?

I should throw out there that the wiring of this entire bike is highly under suspicion. Lot's of spices and such going on from PO. I'm seriously considering making it my first winter project to rewire this thing with a new harness. How big of a PITA is it?

Thanks!

I just had that happen to my 75
The left side flashed right side only lit the front signal checked the bulb it was good
Followed the black wire from the rear signal and one of the bullet connectors had wiggled out of the wiring harness
Its under the seat and towards the front of the rear fender
Just follow the wiring from the signals to where the connect up to the harness
Might be worth a shot

Have a look in Tech. You'll find stuff like this....

I would check the bottom of the lampholders ensure there is contact
Its not the problem here but I would do it.
Then I would check the relay Measure that it has power. Listen if it clicks or making sounds,..
And then service the handlebar switch for the blinkers I need to do that now and then
one year there was lots of insects in there

I Guess the Relay

And now for the dumb question... where is the relay? In the switch?

Mine is under the tank towards the front
I suggest listen ... if you operate the switch it can click once

I think putting on a new harness would eventually save you lots of time, especially if the wiring's been dinked with. Provided you can find a good harness. Harnesses are out there but haven't read about them.

In the blinker switch there are some wires that solder into some little cup-like contacts. I think it's a group of 3 -- been 15 years. They're way down in the switch. Most people have trouble with the blinkers until they have re-soldered those, thereafter no problem. The solder was bad to start with and then degraded.
