the flywheel exceeds minimum cranking RPM, the flywheel 's magnetic lines of force pass through the ignition plate components to produce voltage in those circuitsThe flywheel must be in good condition and correctly located to ensure proper ignition timing and sufficient charge coil outputCharge CoilAll Models charge coil consists of many windings of wire wrapped around metal laminationOnce the flywheel exceeds minimum cranking RPM, the flywheel's magnetic lines of force pass through the charge coil windings to produce approximately 300 volts of alternating currentThis voltage is supplied to the ignition module or power pack to operate the systemSensor Coilthru The sensor coil consists of many windings of wire wrapped around metal laminationOnce the flywheel exceeds minimum cranking RPM, either by manual or electric starter, the flywheel's magnetic lines of force cutting through the sensor coil windings produce approximately voltsIgnition ModuleDeluxe
