Claim Text:
1. A method for monitoring an ignition system, wherein the ignition system comprises a charge coil for charging the ignition system, a primary coil and a secondary coil, said primary coil and secondary coil being arranged to generate a voltage for spark generation, a flywheel having two or more magnets, and a control unit, the method comprising the steps: a) providing a separate coil adjacent to at least one of the charge coil, the primary coil and the secondary coil, the separate coil having a separate coil magnetic circuit, the separate coil magnetic circuit being separate from a magnetic circuit or circuits of the charge coil, primary coil, a secondary coil; a2) rotating the flywheel to generate the voltage on the charge coil and primary coil, and generate a magnetic flux at the separate coil; b) using the control unit to monitor the magnetic flux at the separate coil; and c) using information regarding said magnetic flux as input for controlling at least one property of an operation of the ignition system, wherein the property comprises determining a direction the flywheel is rotating.
