S-SERIES INSTRUMENTS
INTRODUCTION
Instruments used on S-Series trucks include voltmeter,
fuel gauge, oil pressure gauge, water temperature
gauge, speedometer, tachometer and air or vacuum
gauges, plus oil, water, brake and power divider lock
warning lights.
All of these instruments are located on the instrument
panel in a demountable instrument cluster (Figure 1)
directly in front of the driver. Gauges and panel lights of
the cluster are connected to the vehicle electrical system
by a flexible printed circuit.
Optional gauges for such other items as engine oil
temperature, transmission oil temperature, hour meter,
etc. are located to the right of heater controls in a
separate panel. Optional gauges are wired independent
of the printed circuit.
INSTRUMENT CLUSTER
The instrument cluster is a reliable, quick-disconnect
package for the most commonly used instruments.
Should the need arise, cluster body can be quickly
detached from the instrument panel for quick access to
any of its components. Either the complete cluster
assembly or its components can be replaced.
