In an off road vehicle having an internal combustion engine, an alternator, a starter motor, a battery, a brake, a magneto, an accelerator pedal, a key switch having an off position, a run position, and a start position, the starter motor being operative only when the key switch is moved to the start position, control circuitry for selectively operating the vehicle as a pedal start vehicle wherein the starter motor operates when the accelerator pedal is depressed, and the engine stops when the accelerator pedal returns to a rest position thereof, the control circuitry including,
- first circuit structure coupled to the magneto and to the starter motor, the first circuit structure responsive to movement of the accelerator pedal away from a rest position thereof to enable the engine to run and to energize the starter motor,
- the first circuit structure further grounding the magneto and deenergizing the starter motor when the accelerator pedal returns to the rest position,
- the first circuit structure further preventing initiation of operation of the starter motor when the engine is rotating.
