Abstract

An engine start system for use with a ground engaging vehicle, the system including an input device, a processing circuit, a display and an engine controller unit. The input device produces a signal when depressed, the signal initiates the application of electrical power to the engine start system. The processing circuit is activated by the application of electrical power thereto. The display is communicatively coupled with the processing circuit. The input device produces another signal when depressed. The other signal is detected by the processing circuit and the processing circuit, in response to the other signal, sends either a PIN request notice to the display or a start signal to the engine controller unit.
