Principles of Operation Flywheel '11 The flywheel contains permanent magnets necessary to ener- gize the sensor and charge
cutting through the charge coil windings produce between 200 and 300 volts of alternating current (VAC)This voltage is supplied
to the power pack to operate the ignition system Sensor Coil (Timer Base and Sensor Coil Assembly) sensor coil consists of
many windings of wire wrapped around metal laminationOnce the flywheel exceeds minimum cranking RPM, the flywheel's magnetic
lines offorce cutting through the sensor coil windings produce approximately voltsThis voltage is supplied to the power pack
to control small electronic switches (SCRs) which, in turn, direct power pack output to the correct ignition coil primaryPower
