even with RBT module removed the brake light still stays on. I've got continuity from both wires feeding the front brake switch all the way to their pin in the connector under the seat. I'm assuming the problem has to be between there and the light housing.

 

If you disconnect the seat connector do you have continuity between O/W and R/Y on the main harness side, if so disconnect the right hand controls and the rear brake switch and check again. I bet you have a pinched wire in the right hand controls housing. When you changed the switch did you wedge the front brake lever when you put it back on?

 

 

1. Review wire harness if it runs under rear fender.
If bike was lowered then it becomes easier for tire to scrub against wire loom if your model runs under rear fender.

2. If bike uses an incandescent two filament bulb then one filament (running light) can break and touch the other filament (brake light) and that will cause brake light to stay ON.

 

Ok here is the final update... I AM A COMPLETE DUMBASS.
Before I started any of this.. I checked the fuse for lights and all good. I found a BUNCH of stripped wires. Apparently in the off season some critter got up under my tank and started eating wire insulation. Got all of those fixed. New rear brake switch, new front brake switch. New rear bulbs.etc..
After chasing every wire I could find, I noticed in my manual wiring diagram that the same wire supplying power to the brake switches, also supplies power to the horn. I turn on the key and there is no horn... Definitely NO POWER TO THE WIRE.. I think it is the orange/white wire.
So I look in the wiring diagram again, and notice that this wire goes to the ACCESSORIES FUSE, NOT LIGHTS.
I pull the accessories fuse and it is blown clear as day.
Anyway. All wiring issues fixed. All brake lights and switches good to go. Putting it all back together and getting it ready to ride.

Thanks EVERYONE for your tips, advice and opinion. I truly appreciate the help.

I always appreciate it when people update their resolve, helps others down the road with similar issues. Glad you got it sorted

 

Just a random here who wanted to thank the members and Op of this thread, I had an issue where my brake light was constantly on showing no brake response from either brake lever after wiring in a new brake light. After checking everything obvious (Wire connections, correctly wired, checked front and rear pressure switches by disconnecting, still getting a constantly running brake light) I came across this thread and noticed that my horn and my low beam headlight weren’t working. Sure enough, when I checked the accessory fuse, mine was blown, so I replaced it with the extra fuse in my fuse box and she’s working great now, and I even have a working horn and low beam

Long story short, if it’s not obvious, check the dumb little things like fuses, this thread definitely got me on the right track, thanks guys 🙏
