I got it going, but I thought I'd do a write up anyway, to show that you don't take anything for granted. And maybe help someone else.
Working on an 04 Chopper, which has a cam sensor, instead of the crank sensor, but other than that, diagnostic will be similar.
Had a 300 mile road trip planned today, and was going to meet up with several guys from SL. Stopped for gas, and when I went to start it up again, it back fired, then wouldn't start.
Pulled a spark plug wire, and checked for spark. nada. While I was waiting for a trailer, I started to think over all that I had done to the bike that might have contributed to this situation. New EHC, VR, clutch cable. Probably broke a wire messing with the harness.
Always start with the simple things when checking wiring problems. Pulled the cam cover off and checked the cam sensor. It checked out ok. Checked the wiring at the ignition module. Had all the lights on the EHC and ignition module were on like they were suppose to.
I ran into this same thing when I was buying the bike, and it turned out to be a broke wire, but I had power everywhere I was suppose to, and continuity of all the wires were good.
Only thing left was the coil. Pulled it off and it checked good. Continuity on the wires to it was good. Put a new coil on anyway. Still nothing. Swapped ignition module with another bike, still nothing. Called and asked the advice of someone else. Still nothing. Rechecked all the wires again. Still nothing. Rechecked cam sensor. Still tested good.
Now I'm pissed! Dug around and found another cam sensor, installed it, hit the start button, and it fired right up. Rechecked all the wires again, install original cam sensor. Nothing. Laid them on the bench side by side, and they both tested the same..
Put the new one back on, buttoned everything back up, and went for a 60 mile ride.
