Break light on the right side goes out when you hit the brea

Postby dwbob » Sun Sep 04, 2011 8:24 pm



I am not sure why but when I hit the breaks (hand or foot) the right upper break light goes out. I replaced the blub yesterday but it still does it. I am trying to learn more about repairing my bike (1985 1200 A) and could use some help.


Thanks

I'm not sure what you mean here. When you use the brakes the right upper brake light doesn't come on? Comes on then goes out? Or the the tail light goes out when the brakes are applied?
Need some kind of electrical tester. Test light or a multi-meter. First see if you are getting 12V when the brakes are applied. If so start checking the ground wire for a bad wire or ground. A bad ground will cause strange things to happen sometimes. If you have 12V and a good ground you need to get a wiring diagram and start working back from the bulb.
Enjoy the ride. They are all good, just some better than others.

Thanks for the advise. Let me see if I cam make it clearer. The tail light is on in the trunk. When you hit the breaks, instead of getting brighter, the right one goes out while the left one get brighter as it should. When you release the breaks, the light comes back on.

I'll start looking for a bad ground and see what happens from there.

Yes it's a double filament bulb. Your right it's not suppose to work that way. Testing should chase down the problem. Let us know what you find.

the tail lights turn off when the brake lights turn on. my guess it you have a bad brake wire or connector in the right socket if you swap left and right bulbs and the right light still doesnt work

good luck

Sounds like a bad negative/earth connection on the bulb that is going out.. Follow the negative/ground wire and see where it connects to the frame and make sure there is no rust and the wire is conducting (Wire not broken).
