Ive got a 48...I just did a switch wire extension by cutting/soldering and plugging back into the molex. I tested afterwards and it worked fine so I don't think I have a cold joint. Since then I taped up the wires but nothing was exposed that I know of.

I took the pins out of the rear light connectors in order to fish the wire out of the frame rail/extension housing thingy. The colors are lined up again.

Finally, I cut the license plate light and wired in two LEDs. Two ground to the black and two white wires to the red.

Somewhere after the handlebars something happened. Now, my horn does not work, my running lights do come on, the signals and brake light do not work but the high/low beam switch does work. Also, there is no problem turning on the bike.

Any ideas before I pull all the wiring apart?

 

sounds like the fuse-
i blew that fuse with a horn short... i had the same symptoms as you. did you check your fuses yet?

 

Well that's a start. Clutch clamp was pinching a wire causing the blown fuse.

Horn works now. Turns out that in my rush I wrapped both license plate wires together. That is remedied now.

So, all lights are on and the horn works now. Still no turn signals/brake light. Did I blast my TSM? I'm assuming these control brake lights as well on the 48?

 

Swapped with my buddies nightster...same p/n no dice though.

Edit: found another fuse o.O

I need a bike with less electronics and more metal to chop on
