No brake light

[oldschoolgs1100e]

Hi. 81 gs1100e. Brake light not working. I tested the rear switch and got .3 resistance,ok. took apart the front brake switch and cleaned it up. Tested all rear lights off the bike w/power to them and they work. The double filament bulb main works while MC is running but brake light does not. The panel up front works and tells me there is no brake light. I'am waiting on a manual but in the mean time does anyone have any suggestions? Thank you.

Focus on rear switch first - does it have power with ignition on? then follow the wire from rear switch to light to make sure the connections are good. Since the tailight works, it seems that the ground side of things is ok. Basscliff's site probably has decent wiring diagram, so take a look!

Brake light filament blown?

Basscliffs site has great wiring diagrams so you can see where faults could occur
