Unplug the rear lights. Hook the leads up to a volt meter, turn everything on and hit the brakes.
See if there is current going to the lights. That's step one.
If there is current going to it when you hit the brakes, the problem is in the lights.
If not...
Next check the lever switches at the brakes. There will be two leads going to the switches, one must have current in it.
If no current is there, it must be way back at the source. Follow that back to the battery/stator system.
If there is current...
It must be some where from the brake switch to where it plugs into the brake lights.
At this point it could also be that both brake switches are bad, but that's unlikely.
I'm assuming you have a mult-meter.
Just keep eliminating places the problem can be at.
You can also disconnect the battery and use the resistance setting to test these things.
