Reluctor Alignment - MSD Pro-Billet

[TheMonkey]

i talked to MSD tech. the signal from the sensor the distributor sends negative voltage when reluctor is not in front of sensor, and sends positive voltage when reluctor is in front of sensor. the spark signal occurs at the zero voltage point from negative to positive, and the reluctor alignment with sensor at that spark point is when the reluctor's leading edge is just in front of the sensor.
