consists of many windings of wire wrapped around metal laminationOnce the flywheel exceeds minimum cranking RPM, the flywheel's
magnetic lines of force cutting through the sensor coil windings produce approximately volts This voltage is supplied to
the power pack to control small electronic switches (SCRs) which, in turn, direct power pack output to the correct ignition
