The engine is the main component of the vehicle drivetrain and has many components and associated wiring. The relationship of the engine and these components is shown below in the pictorial diagram. The engine is started by turning on the MASTER switch which supplies voltage from the batteries through the MASTER relay. When the START button is pushed, voltage is supplied to the starter which cranks and starts the engine. Once started, the engine can develop up to 405 horsepower at 2350 rpm and deliver this power to the transfer assembly. The transfer assembly then sends this power to the transmission. 3-57
