Check the wiring under the parking brake and make sure that's all looking good. When I'm troubleshooting the blinking light, I pull the P-brake switch and disconnect it so it's out of the equation. Then I go fiddle with the wiring on the M/C until the light goes out, then add in the parking brake switch and make that work.
Sometimes the switch on the M/C seems to like the wires one way or another. Also, those switches can fail. Use an ohmmeter to check continuity between the two connections with the wires unhooked, and check continuity between each connection and the body of the switch. None should be connected. If any are, your switch is probably bad. But the good news is that you can swap the switch without needing the bleed the brakes (unless your M/C has a failure).
Wow very informative. I'm decent with mechanical stuff, but I suck with electrical issues.
Thanks, Brian
