Wire to Jobbers:
Power from key to coil. Test light to one of the coil lugs, so you know with key on you have power to the coil.
With the crank/cam sensor plug [connector] removed, use a volt meter and run the probes into each wire. The sensor uses one wire wrapped around a metal dowel peg call it. You spin the engine and this should make AC volts, but the volt meter will show if it can pulse voltage out of it. This should flicker on and off like an old set of points.
The EHC or the spark box. The crank sensor just can't be directly hooked to the one side of the coil like an old set of points. I think the square wave might need a conversion to trigger the on/off inside the processor, let alone the advance needed to start and run.
The troubleshoot tree:
Can't be the power if it goes down to the coil's lug.
Can't be the coil being one of the most dependable jobbers on the bike/cars [with many on one engine].
Could be the sensor if no output/low output, heading up the wires.
Could be the processor if self codes with LED's, but the processor renders the bike a boat anchor, as will the crank sensor being that heart or pulse made as well.
Ign System Loop:
1. Crank/cam sensor.
2. Coil.
3. ECH, spark box, processor [advance purposes].
4. Power [key switch] 12v at battery.
