Headlight main beam not working but flashes when using the pass signal
 

Hi All

Just found my main beam wasn't working- swapped fuses and bulb and still can't get the bulb to shine. When I use the pass button the light shines and goes off when I release the button

Where am I going wrong? The low beam and high beam both don't shine.

Check the headlamp relay under the seat, particularly it's connections. Pull it out and clean everything up and try again to start with. If still no joy check the relay (off the bike) with the trigger terminals connected to a battery with a multimeter across the load terminal and see if it switches correctly.

The reason the "pass" switch works is that feeds the main beam directly and bypasses the relay. Normal high and low function is controlled by the headlamp relay which is triggered off the ECU so only works when the engine is running. The pass switch illuminates main beam without the need for the engine to run.

I am assuming you that you are trying the main and dipped beam with the engine running? If you're not, then that'll be why they aren't working! ;)

Thanks
I'll check that out now
