I really need some help as to what to look at on my bike. It is an 03 fxd carb. nothing but carb kit and exhaust done to it. I am getting no spark from coil. Checked wire going into coil and only the center wire is getting fire the outside wire are not. I have never had trouble before, only 27000 miles, this year it began to get harder and harder to start, it would turn over fine but it turned over quite a bit but would finally start. now it will not start at all, getting no fire/pulse out of the coil where the wires plug in. I start a new job on Monday and would like to make this a regular ride since I rarely have the time to ride anymore. Any help would be appreciated, and I do appreciate those that told me to check the wire on back of the coil.
