If you only have one brakelight, check the bulb first, If you have two or more, and none work, brakelight relay, then wiring.

Made any changes to the bike latley? Sometimes you can mess stuff up by accident.

I'm running more than one and none work. Is the relay what the wire is plugged into? How do I test it?
Thanks

The relay is a little box (1 in by 1 in by 2 in) with the wiring plugged into it. When you push or squeeze the brake with power on you should hear it click. The starter relay should be near it and they are interchangeable. (on baggers anyway) Try the other one.

I should also mention the fuse, but if it is blown, it is the warning, NOT the problem. Also the fuse is shared with other stuff you would notice being off.

Figured it out. After checking all my connections ten times I finally figured out that since my rear wheel was off the bike when I hit the brake pedal the sending unit had no pressure built up. I wedged a piece of metal inbetween the brake pads and pumped the brake a few times and the brake light came on. I lost half my hair figuring this one out so I hope this helps atleast one person not to make the same mistake.

It isn't a good idea to push the brake pedal without the pads in and rotor in place. The pistons in the caliper will pop out of place and the caliper might need to be taken apart to get them back in place.

Remember when I said "made any changes to the bike lately?" in my first post?

I don't know how many times that sort of thing has happened to me and others I know. Stuff that seems like nothing ends up affecting something else.


I am glad you got it fixed, and passed the knowledge on to the rest of us.
