Great thread, thanks to the OP for getting it started. I bought a 03 BRP with a BD kit already installed and it is turning out to be a headache. When I use the right turn signal, everything is normal. But when I try the left switch, the head light blinks. I have traced the wires and everything seems to be in order. BD says I probably have a worn out handlebar switch and I need to replace what I have. Funny thing is, I started to work on it this morning and what do you know, the left blinker starts working. Problem solved, right? I take out the small ni-cad battery to put a trickle charge on it, put it back in and test again....and its back to the blinking head light. And now my rear running and brake light are out.
Has any one come across something like this before? I'm almost ready to tear the system out and start over again, as there is no telling what the original owner did.
The bike has the stock stator (as far as I can tell).
