Test and change circuit board in front hand brake housing

[BigSpenda864]

I am having an issue with my brake lights staying on all the time. From what I've read, it appears I may have a problem with the circuit board in the housing with my front brake. Can someone post a "how to" for testing and replacing the circuit board? I am not the best wrencher so I do not dare take the housing apart and start messing around without knowing exactly how to do test and fix it. Thanks!!!!

Anyone?

I have to ask how you determined that your problem is with the circuit board for the front brake? Did you try disconecting the circuit board or the rear brake switch?

And how are you with a multimeter?

I haven't determined it is a circuit board problem. I am just going by what everyone on here thought might be causing my issues. Someone mentioned testing the the board and, if it was faulty, replacing it with a new one. I have only messed with a multimeter a few times. I basically know who to work one but I don't have much experience.

Have you checked your brake cylinder fluid levels first make sure they are okay? :loony:

I haven't determined it is a circuit board problem.

Then you need to do some troubleshooting first. Try something simple like disconnecting the rear brake switch! Is the problem still there?

Now there's a rock and hard place! What "everyone" says may just fix your problem OR you may end up spending $500+ for a WirePlus then find that your problem is still there after the install. But it's your choice how you want to approach the problem...

Someone mentioned testing the the board...

Did "someone" also mention how to test it? I know if I were going to test mine I'd disconnect the backbone connector on the EHC and look for continuity and shorts...

...and, if it was faulty, replacing it with a new one.

Sounds logical!

If you're not comfortable with a meter do you know someone that is (they don't have to have a mechanical bone in their body as long as they understand electricity...)

Bingo Brooks!!! That's exactly what I'm talking about... K.I.S.S. :2thumbs:

Check the most simple and obvious things first no matter what else you may read or hear!

Had the same problem with the brake lights staying on.

It was the reed sensor.

Just search the internet for hamlin firecracker 59021 - that's what BDM used.

Hamlin 59021 Aluminium Minature Firecracker Sensor

I installed this one and all was good.
