brake sensor problem

[dnespolo]

I took the right handlebar control apart because for the 10th time the idle cable came off again (every time I completely turn the accelerator the cable snap off from the grip) but this time the light brake sensor came out too and now i can't put it back and it is not working. My question is this does the sensor need to go back inside the magnet or just near to it? Or once the sensor come out is not good anymore? Or am I doing anything wrong? Also any idea how to deal with my idle cable problem? Do anybody had the same issue?

Had the same problem with the brake lights.

It was the reed sensor. It just hast to be near the magnet - not touching it. These sensors break very easily - I had to figure out :angry:. It happened to me when adjusting the break lever by turning it. When the wires get tensioned, the sensor failes.

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.

So your are saying the sensor is not good anymore? I put it back earlier and the break light would stay on, took it off again and now nothing. I guess i'll go ahead and order and new one.

The magnet is probably ok it just has to be the right distance when you pull the brake lever but not so close the brake light stays on.

How do you keep it in place?

Tiny set screw.Hard to see but its there...

How do you keep it in place?

It has a very small 1.5mm hex screw in there

I couldn't get to the small screw that keep the sensor in place so I had to take the bike to the shop for other issue and they fix it for me. I bought a new sensor but the shop used the old one so I got a spare one if anybody need it. I think it was $24.

DUDE almost the same thing happened to me.....I took the RT side controls apart to clean and check the connection on the circut board,put it all back 2gether now..NO FRONT BRAKE AT ALL......I have no clue where to even start on this one...

Did you take out the wire feeding into the handlebar control? You have to have it adjusted to a respectable level when you put it back in. It can not be too far (will never trigger the brake) and cannot be too close (Brake Lights will be on all the time).

You can see the Reed switch and magnet through the space between the control housing and handlebar. It looks like the below:

If you didn't take the wire out I assume you pulled out a wire off the board which is easy to do on the 04's as they are simply just soldered to the boards.

Figured my cracked reed sensor was my problem. Happened after a surprise field throttle cable repair. Ordered the new sensor from Donna. Suppose I should have checked first but I think my problem may be in the board. After the new sensor wouldn't trigger brake light with handle, I tried directly with a strong magnet and then bypassing altogether and touching wires. No light. Rear brake triggers fine so the lights work. New board or any other ideas? Much obliged
