I have had my triumph since 02 and I stripped it down from the begining. I installed some aftermarket turn signals and stripped off the front ones. Soon after everything stopped working. My horn, turn signals and brake light all seem to be done. I tried everything. First I thought maybe it was an open circuit problem, then I thought maybe the factory wiring was bad. FYI, My lights come on. I've tried reinstalling everything to stock but it still doesnt work. If anyone knows where I can get a wireing diagram or has had the same issue please respond.
