2003 GL1800 Low beam headlights don't work

[over60]

I have checked Relays, fusees, bulbs, taken apart the starter switch and nothing. Where do I go now, to the dealer? I am very frustrated about this. Please help!
Thanks

Hi Fred, have you checked the block connectors and electrical connections? how did the problem come about? did the light suddenly stop working or can it be connected to some other event such as maintenance or minor accident? The more information you can give the better chance you have of getting help.

Hi Fred
I have just gone through the same problem. My highbeams would come on but not my lowbeams and the relays and fuses were fine. I found that the connector pin was corroded. There is a connector block in the front left side of the fairing with 2 gray and 1 blue pin connectors. It is the blue connector that you'll need to take apart and clean the pins. The best way to get to this conector block is to remove the fairing. Would suggest you give both sides of the pin connector a good cleaning and then bend the pin for the lowbeam slightly outward to ensure a good contact. Once you snap the connector together, place one of the light bulbs in one of the lowbeam sockets, turn on the key to veryify that light comes on.
Hope this helps, Steve

I just noticed the lights were not on one evening. I had recently operated the wind shield. moved it up and down a couple of times. No minor accidents or anything like that. Don't know if that helps. I did visit a dealership today and the mechanic said it is possibly a ground wire issue.
Thanks for your suggestion about the connector block. Sounds like a time consuming job taking the faring off. I try not to ride much at night and when I do the lower lights help and I run the high beams in the daytime for now. The weather here in Michigan is going to turn to winter soon and I want to ride as much as I can for now.

I know this is going to sound silly, but since no one has mentioned it I thought I should.

I have an 03 GL1800 as well and my bike has a switch inside the left glove box located at the front of the box. Took me a day or so to find this out the first time I put something in the box and turned the light off. Might be worth checking.

Ride Safe!

Or maybe! Checked the bulb, can burned?

I cannot remember for certain so I could be wrong, but the last time I removed a 1800 fairing I think the RH headlight plugs come from the RH huge multiplug, and the LH headlighjt plugs come from the LH multiplug, if this is the case, the same problem would be with both LH and RH plugs at the same time. When I fitted reversing lights to my trike, I tapped into the RVS wire at one of the fairing multiplugs to switch the relay. I soldered a connector to my multimeter + so I can plug in several probes I soldered onto wires (darning needle). I did this with the fairing in place, cannot unplug them but you can probe both sides of the plug and socket to see if the signal passes through the plug or not, before contemplating fairing removal. You could also try proper switch cleaner and give the plug bit of a rocking.

I would remove the tank cover/radio unit, that should let the fox into the hen house.

Fred, you do not say if you are the first owner of the bike nor if the low beams have always always come on with the ignition switch turned on and the bike not running.
So, I have to suggest that there is possibly a Low Beam Cutout Harness installed on your Wing that you do not know about and it has possibly failed. Electrical Connection manufacturers one and Cyclemax sells it. Click this link to see the item: http://cyclemax.com/inc/sdetail/gl1800_ ... 120/125827.
