1981 GL100 Starter Switch.

Postby OU81288 » Tue Dec 14, 2010 7:58 pm



Has anyone encountered a problem (or wear) with their starter switch not allowing the head light to stay on when the engine is started? The switch works fine to crank the starter. The headlight goes out while the button is depressed to start the engine and should come back on. Now I have to push the starter button to the side instead of in to get the headlight to come on. The head light will stay on sometimes and go out others. I am guessing it is worn out, but thought I would ask.

Thanks,

Tory

The starter switch is actually two switches in one - it has two sets of contacts: technically, it is a momentary DPST (dual pole, single throw) switch.

One set of contacts is normally open, and when the button is depressed, it supplies power to the starter solenoid, cranking the engine.

The second set of contacts is normally closed, and when the button is depressed, it interrupts power to the headlight, to make more power available to crank the engine.

The problem is that the second set of contacts in your switch is either dirty or worn. You can disassemble the switch and clean it out with electrical contact cleaner (NOT WD-40!) and there's a good chance it will fix your problem.

+1 for cleaning. Had this problem on a CB750 a few years back. As mentioned by WA make sure to use electrical contact cleaner. Should clear your issue right up!
    You only need two tools in life - wd-40 and duct tape. If it doesn't move and should, use the wd-40. If it shouldn't move and does, use the duct tape!

I got the switch apart and you guys were correct; all junked up with crud. I cleaned it put it back together and it works like new. Here is a couple pictures may help someone else.
Thanks again.
