DESCRIPTION AND OPERATION

Tachometer (if Equipped)

The tachometer (17360) is an electrically operated gauge that indicates engine speed in rpm. In vehicles with gasoline engines (6007), the tachometer receives its voltage pulses from the ignition coil when the engine is running. In vehicles with diesel engines, the engine's speed is indicated by the engine rpm sensor.
