Gee, the whole bloody thing is a switching amplifier. No way in hell that pickup is going to turn the coils on and off all by its lonesome. Primary voltage in the coils is probably close to 50-60 volts at peak, and the supply voltage is only 4.8-6.
The v into the coil is in the order of 300vdc not 50-60. The sensor is just that,
it trips an SCR which dumps the HV, stored in a cap, into the coil
