No tail lights

[84ROYAL]

Hi there everyone. My son and I were out for a ride and got pulled over and the cop informed me that i had no tail lights. Good thing is the cop let me go and told me to get them fixed. Ok i will get to the point. I have went over the hole wiring and cannot find a broken wire and also have found out that when I apply the front brake the brake light does not work but the rear does work. Any ideas on what is up. Does the cmu have something to do with the fact that i have all the lights on the bike but now running lights on the back of the bike.

The front and rear brake switched are wired in parellel, either one will turn on circuit. Then they run thru the CMU dash computer, and should provide and indication of brake light failure.

 

If no indication of failure and circuits works with rear switch, I would suspect that the front switch is defective-most likely the button is dirty/jammed.

 

You also stated 'no tail lights'. Does this also mean no running light?

I had the same thing happen to me the other day. The front brake switch, under the brake lever, is defective. I took one off of my parts bike and spliced it in the place of the old one and shazzam, it worked.

There is a possibility that a previous owner has jumped the CMU in preparation for LEDs.
