This section describes the location and function of
various switches and sensors fitted to the vehicle to
monitor all major components and systems. Gauges

relay this information to the operator.
Note: Always make sure all gauges, warning lights
and controls are working properly before operating the
vehicle.

engine at all times and sends a signal to the engine
check light (2, Fig. 2) and engine stop light (1, Fig. 2)
on the dash panel to alert the operator of a fault in the
engine circuit. Refer to Section 110-0030, ENGINE
