    Intermittent front brake light

    The wiring in the front brake lever is responsive but not working consistently. When I jiggle the lever itself that can even make the light go off. Took a closer look at the wiring underneath the handle and everything looks clean. Not exactly sure why it is having a problem. Any ideas and possible solutions would be appreciated! Thanks

    Seems as though the contact itself isn't working properly. I don't know if its te way it is positioned on the spring on the contact but I took it apart and now it doesn't work at all... Here is a picture of the tiny contact itself

      Go to the GS OWNERS..at the very top is a STICKY.. Click on it and look for the switch adjutment tutorial...It just easier than me taking 10 minutes to type it all out.

      I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

        I checked it out further. The spring on the lever contact was at an angle and thus was not making consistent contact. I took it off straightened it out and now its working fine!

          I am also having a problem with my front switch. It seems to be intermittent as well, although the time with the switch working seems to be far less than the switch not working.

          Here's what I've done so far. I disassembled the switch, removed its components from the brake lever, and cleaned them up really well. This didn't fix it.

          I measure the voltage at the switch board and I got close to 12V. Since there's is electricity going through there, I thought bridging the two copper contact points on the switch board would light up the brake light. So, with the switch disassembled, I placed the copper U-shaped contact bridge across the two strips of copper on the switch board. This did not light up the brake light.

          So I thought I should test the continuity of the U-shaped contact bridge and it seems okay, my multimeter's beeping confirms it.

          The rear brake lever activates the brake light just fine, so I know the bulb is okay. Does anyone have any idea where I should go next? Thanks.

            Follow the two wires from the switch into the headlight bucket. One of them is the "hot" wire, the other is the "switched" wire that leads to the brake light. Since you have power at the switch, I am guessing that the connection in the other wire is kind of "iffy". You can disconnect the switch wires from the harness and bridge across the harness wires to see if the brake light comes on. If it does, your problem is evidently in the connections to the switch or in the "switched" wire between the switch and the connector in the bucket.

              Thanks, Steve. Although I don't entirely understand all that you said, I followed your advise and tracked the wires from the switch to somewhere behind the headlight and found this connector:



              The connector is in the center of that picture. The cable is pink but the flash from the camera made it look yellow. I unplugged the wire and plugged in back in. There are two holes there, one worked, one didn't. This fixed my brake light problem.

              Is anything supposed to go into the other hole?
