Principles of Operation Flywheel
rv The flywheel containsand permanent magnets the flywheel the necessary to energize the sensor charge coilsOnce
exceeds minimum cranking RPM, the flywheel's magnetic lines of force passing through the sensor and charge coil windings produce voltage in those circuitsWhen the flywheel is in good condition and correctly located, it controls ignition timing and output from the charge coil and power coil All ModelsThe sensor magnets are in ring around the flywheel hubThe stator, charge coil, and power coil magnets are around the flywheel rimCharge Coil (Stator and Charge Coil Assembly) The charge coil and power coil are located on the stator They consist of many windings of wire wrapped around metal laminationOnce 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 ignition system V4has one power coil and one charge coil V6has one power coil and two charge coilsone for cylinders 1, 3, and 5, and one for cylinders 2, 4, and 6
