No High Beam

Postby Randy S » Sun Apr 08, 2012 11:01 pm



I bought a 78 gl1000 so the wife and I would have something to enjoy together. We used to ride but have been away from cycles for 25 years. All has gone well making minor repairs and getting used to a larger bike. It takes some practice getting used to riding in the Nebraska wind. When checking the bike out for night use I realized both hi and low beam on the switch only lights the low beam. The hi beam comes on if you hold the switch between hi and low. I changed the switch with one obtained from a salvage shop. The new one still does the same thing. The wiring diagram shows power coming in on a black/white wire, low goes out on a white wire, and hi goes out on blue wire. When testing with a test light the power comes to the switch on the white wire instead of the bl/w wire. This explains hi beam only working when the switch hits both terminals. Before I start cutting and changing wire connections has anyone else run into this problem? I removed 4 wires from the acc terminal that went nowhere and there are still wires in the fairing that don't connect to anything so the wiring could have been messed with before. Any ideas or suggestions will be greatly appreciated.

Looks like you have a Windjammer SS fairing on your bike, I believe they have a 9-pin connector.

According to wiring instructions on the Vetter site;
From the fairing plug, 9-pin

White = High Beam
Yellow = Low Beam
Black = Ground
Violet = Left Turn signal
Dark Blue = Right Turn signal
Green = Running lights
Red = cigarette lighter or other option
Brown = accessory
Orange = accessory

Yes it has a Vetter SS fairing, bags and trunk. I wired the fairing into the switch the same as the old switch. This matches the info you gave me. The power seems to come from the junction on the white wire to the low beam and switch. The wire that should feed power is dead.

Did the PO do any wiring inside the fairing to hook up other accessories? Could be the wiring on the fairing plug is crossed somewhere. I would doubt that you would have problems with two switches especially where one was new. Power will only flow to that switch when the key is in the on position.

Went back and traced wiring in fairing, found jumper wire soldered between left marker and low beam wire. This explains the power backfeeding to the switch. Cut out the jumper and traced dead power wire back to worn starter switch. I am in the process of fixing the switch but now have to find new spring after old one flew across the shop never to be seen again. Thanks again for the help, now its time to go raid the wife's pen drawer!
