Greetings, and help? Frame info and Rear brake light issues

[Love2fixit]

Well hi from Callahan Florida. Just bought this beast of a 2003 Big Dog, was told it was a pit bull. Has the 107 super sidewinder and Baker 6 speed tranny. Love the bike. Only issue is no brake light. It's got the single light of multi LEDs on the fender. The turn signal will light it bright and flash so I know it's not the light itself but I can't imagine both front and rear mc pressure sensors are bad. Im a mechanic so I know a little but need some info on how this system works. Seems there's a silver box under the seat that controls the signal blink. Does this have anything to do with brake lights also? A wire diagram would be nice too.

Well also I've looked at alot of pics of pit bull bikes and haven't found a bike like mine with the rake my frame has. I thought I read a couple posts in here that there were different frame options within the different models? Anyone know what frame this is? I know the forks aren't original because I have those forks separate when I bought the bike. Any info would be great. Thanks

From the pics I would say you have a 03 Chopper. If it has rear suspension it is not a Pitbull or Ridgeback. Only two hardtail models made.

It has suspension. That was another tell tell sign that I might not have a pit bull.

Yeah its a chopper....they came out with 10 over front forks

Thanks. Since I was told it was a pit bull that's what I have been looking at. Didn't know they had a chopper line and didn't think of it. Thanks.

It only has one pressure switch and its on the rear caliper....front it just basically a contact wire in the hand control that sends the signal to turn the light on...might be a wire messed up or the switch itself

 

[Love2fixit]

Actually I have the same switch on both masters have the same switch on them.

Looks like someone removed the turn signals and added that brake light? Stock should have had left and right brake lights as part of the turns.

 

[Love2fixit]

Yea, turns have been removed. But brake should still work. I'll prob just wire it right off the battery through the rear switch and out to the light like I have on every other bike I ever built.

I would still look at what they did. If you can find the old wires both Greens should be brake hot, Blacks are the grounds. Tape up both Reds.
