cb750 brake light help
« on: September 22, 2011, 12:12:11 PM »
Hey guys, been reading a bunch of other threads on here to try to help me determine what my problem is with this brake light.  I'm doing a cafe build on a cb750k2, and have replaced the master cylinder and tail lights on the bike.  The tail lights I put on the bike are LED lights, and I get the tail light to come on with the high/low beam switch on the bars, but can't seem to get the brake's to fire up.  I know this light can work as a running light/brake light, because when I stuck the wire that powers the tail light into the brown wire (brake wire) I get a brighter light from the increased voltage... I just can't seem to get it to work at the same time as a running light, then eventually brake light.

The master cylinder I put on has it's own brake light switch, so I'm no longer using the pressure switch that was on the lower triple tree.  I've checked as many wires as I can see looking for a possible ground that isn't connected but haven't found anything... any suggestions?  I guess it's also worth mentioning that I don't have any turn signals hooked up, nor do I have the turn signal switch on the bars anymore.


 Oh... and here's the build, as I know everyone likes pictures.  Don't mind the hideous paint job from the PO.

fixed my own problem... the rear brake switch was too tight, so brakes were on all the time.  I feel dumb.

Don't be hard on yourself, I started my bike with two coil cables (1-4) disconnected and wondered why she runs like crap.
