Re: No Spark
What you may try is this. Crank sensor installed in engine. Unplug the crank sensor from the wiring harness. Place your AC voltmeter on a 10 or 20 volt range and attach to crank sensor. Remove both spark plugs and ground both spark plug wires to the frame. Crank engine while watching meter. The higher the value you read the better but I will guess and say you need at Least 1.5 to 2 volts for reliability.
It's a very if-ie reading because the waveform coming out of the sensor is not true sinusoidal and the frequency is not 60 Hz. You really need to view the waveform with a scope but it's worth a try with a meter. If the internal magnet is cracked or you have a few shorted turns of wire, it should clamp the output voltage and you will get a low reading.
These type of sensors are self contained and need no external voltage or power supply to function.
