One thing, if you got the dyna S system, they used to give a connector that you were supposed to use to connect a ground wire I think? Been a few years since I put mine on. This connector is or at least was crap. Best to strip a little insulation and solder it on and then cover with rubber cement or electrical tape.
I have know people to have intermittent issues with ignition only to find out it was this connector.
The connector is kinda like a shell that has openings for 2 wires on 1 side and 1 opening on the other with a metal tooth that is suppose to splice these wires.
The ride IS the adventure. The destination is just to get gas!
