Brake light not working

hi all!

I have this really interesting issue with the brake light not working on a 94 Vulcan 750. The volt meter on the blue wire from the harness reads 11.94 volts when you pull in the front brake lever and zeros out when you release it. When I connect it to the brake light or any other test light, it doesn't light either. I hooked the brake light wire directly to the battery and it lights up.

I know call me crazy. I have re-wired other bikes (just recently a 98 Vulcan) and all is good. The bike rides and runs great with no other issues.

Help!!!

Signed

Lost and Confused...

Update - I just hooked up an LED light to the blue brake light wire and it barely lights up when I pull in the brake lever.

Any clues on what to try or check next? Apparently, the volt meter isn't reading correctly.

either ground(s), or really bad connection that cannot support any appreciable amount of current (led's draw very very little, multimeters even less when measuring voltage)
also, how is operation when using the rear brake pedal?

x2 on the connections. a volt meter can read proper voltage accross a corroded connection but the connection won't pass current.

I posted to your other thread as well......

I say inspect the wires running under the fender that snake through it and into the tail light.

A chaffed wire to the fender will short out and cause similar symptoms. if it is not a dead short, it will partially illuminate an LED. It may not blow a fuse since the current draw for the tail light is not enough to trip the 10amp fuse...especially if it has a resistive load such as a rusty wire touching the fender.
