Head Light

Hey All,

So I had pretty much got my bike right were I wanted it for the summer, and I thought to myself, "I bet my light would be brighter if I polished the inside of the lens up a bit," so I took the headlight off, polished it up, put it back on, and now it won't come back on!

I've replaced the bulb and the fuses are ok. Any thoughts? Prolly a short in my wiring huh? I know nothing about electrical. Any advice is welcome.

Check the bulb filaments visually and with a couple of jumper wires to to a battery, to be sure it is good.

Check the headlight connectors with a test light or multimeter for continuity, then trace back thru the wiring harness to every junction or splice until you find power.

What everybody else said about finding the problem, but I'm not getting the part about polishing the lense. I'm assuming you mean the inside of the lense? Even removing the bulb only leaves a small hole in the headlight assembly, how did you reach the lense? I would be afraid of messing up the chrome stuff on the reflector trying to do that. With the bulb in place, it is virtually a sealed unit, so nothing inside should be dirty. Jerry.

I think I know what he is getting at Jerry. My glass lens is kinda cloudy, like it has a white film inside it. How it gets that way I do not know ,nor do I know how to clean it.If any body has a magic trick to clean the glass without damaging the reflector let me know.

Does our VN have a headlight relay? If not, adding a relay would make our light slightly brighter and might last longer...

Yes,it is internal to the JB and is activated by one leg of the stator sending voltage to the JB,as the engine cranks over.

I believe the problem is with the reserve lighting switch. Will I have to replace it? Do ya'll know if the part is specific to each bike model, or would one for say a 1982 Kawasaki KZ750 H3 LTD 750 work? Just wondering because one is on ebay and new the part costs 115 bucks. Thanks.

asbrand, yeah I did. Had a friend who knows a little more about electrical help me a bit. From what I understand, the ground was good, but we weren't getting power. We created a circuit by connecting the multimeter to the fuse box and connecting that directly to the headlight. When we did that it turned on and would stay on after we disconnected the multimeter, but when we would turn the bike off it wouldn't come back on when the bike was restarted. We think somehow the lighting reserve not functioning properly disrupted the circuit.
