Headlight Will Not Come On

Post by BearsGrandpa » Sat Jul 21, 2018 1:44 pm



I have tracked the problem to this point:
1. The bulb is new and both the high and low work when tested.
2. The test on the female plug to the bulb shows,
a) green wire to blue wire has power,
b) green to white only has a flash of power in the middle when toggling the light switch between high and low. It only flashes and does not stay on. I had
changed out the switch for a new/used one thinking the switch was the problem. It did the same thing with my old switch.

Any help will be greatly appreciated.

Probably the start switch. Try flipping the start button with your finger nail several times.

My 1200 lost the headlight. It turned out to be the start switch. You can take the switch apart but be careful, there are springs inside. In any case you take the s=witch apart, clean out the gunk, get it clean! Then polish the four copper or brass dots and put it back together, that's it.

Thanks, guys, I had read about the switch but wasn't sure that it was that. I didn't know if I had a problem in one of the harnesses because of the white wire having power in between high and low. I will try that.

Mine will occasionally act up, but the problem isn't from the kill switch that goes left and right. When you press the starter button, it kills power to the headlight while cranking. Every now and then I notice my headlight isn't on, but if I grab the starter button with my finger and thumb and physically pull it out, the headlight comes on.

Usually it means it's time for some electrical contact cleaner.

Suspect your fuse box -
I had this problem on a 1980 and it turned out the corrosion on the glass fuse ends caused enough heat to actually melt the fuse holder.
One symptom of the fuse issue was the headlight wouldn't work --
If that is it there is a thread about changing the fuse block entirely - you will like the change to blade fuses and it's not that hard to do.

I've had those glass fuses "fail", not "blow" before. Fuse LOOKED fine, but putting voltmeter across the fuse with the power on showed 12v. Seems the fuse element inside the glass came detached on one end.... :shock:

Here's a couple other unusual headlight failures, both happened on my old '77 GL1000 when I still had her - On the big round sealed-beam Automotive-type headlights that fit a Vetter fairing, I had a sealed-beam Halogen light, of course this happened at night, all of a sudden I had no light, either high or low beam. Looking inside the headlight you could see the little internal halogen bulb laying in the bottom of the sealed beam, it had broken off. Fortunately I was near a gas station, and bough a then readily available incandescent sealed beam. I figured the standard sealed beam might be safer on the wing, maybe those halogen's couldn't stand the vibration.

Well, some time later, it too, failed! On a standard incandescent bulb there's a little metal shield inside the bulb right in front of the filaments that directs the light, the little shield broke off from it's mount and slid back over the wire posts that the filaments attach to, shorting the bulb. Bike immediately died like I hit the kill switch, it blew the main fuse!
They say 98% of all Hardleys ever made are still on the road..... The other 2% made it home. :lol:
(I stole this from somebody on another GW site...) :roll:

I cleaned the starter button as suggested. After reinstalling it, it worked BUT, it went out again. Turns out to be in the wires in the back of the button. It's so small I'm not sure I can fix the short. Thoughts?

Did you fully disassemble the switch and clean and polish the contacts?

The first time i did mine i took the headlight out and reinserted the electrical connections, and it worked fine, then the next day it died again. then I took apart the starter switch and fully disassembled it and cleaned and polished the contacts as well as cleaning the years of crap that had built up over 30+ years. Been fine ever since.

yes, I totally cleaned it. It's the wires in the back not the switch.
