I'm not sure I have a lot of help for you, but here's what I know:
- the box on the left fender is the ignition controller. It has 4 or 5 connectors on it; 2-3 small ones and 2 big ones. One of the small connectors is a coax. That's the one that comes from the inductive sensor at the crank pulley.
- the inductive sensor is about at the 1 o'clock position above the crank pulley... I think.
If the engine runs, I doubt the problem is with the sensor or the sensor cable.
