Principles of Operation Flywheel flywheel contains the permanent magnets necessary to energize the sensor and charge coilsOnce
one power coil and two charge coilsone for cylinders 1, 3, and 5, and one for cylinders 2, 4, and 6 VBhas one power coil
and two charge coilsone for cylinders thru 4, and one for cylinders thru 8 Power Coil power coil is located on the stator
assembly It contains many windings (strands of wire wrapped around metal lamination)Once the flywheel exceeds minimum cranking
RPM, the flywheel's magnetic lines of force cut through the coil windings to produce voltageThe voltage is supplied to the
power pack to operate the S.L.DWTM warning system and the Ouikstart TM electronic starting system Sensor Coil (Timer Base
and Sensor Coil Assembly) 121 The sensor coil consists of many windings of wire wrapped around metal laminationOnce the flywheel
exceeds minimum cranking RPMthe flywheel's magnetic lines of force cut through the coil windings to produce voltage This
voltage is supplied to the power pack to control electronic switches (SeR's) which, in turndirect power pack output to the
