GENERAL BESCRIP"T0N
RALLY GAGES
Figure I
The Rally Gage option, available on most models,
consists of an engine water temperature gage, an oil
pressure gage and a voltmeter.
These gages are incorporated into the instrument
cluster and replace the standard warning lamps. The
water temperature and oil pressure gages are
electrically operated from sending units mounted in the
cylinder head and oil filter base respectively. The
voltmeter registers regulated voltage, providing an
indication of the charging system's ability to keep the
battery charged. Continuous readings in either the high
or low voltage red bands can indicate improper voltage
regulation, broken or slipping alternator belt,
a shorted
alternator diode
or a defective battery. Readings in the
yellow band are normal with the engine idling or for
short periods after long engine cranking. However,
continuous readings in the yellow band can indicate
faulty operation. See Section
8A for diagnosis.
TACHOMETER
Figure 2
The tachometer indicates speed of the engine in
revolutions per minute (RPM). The engine can safely
be operated up to a maximum RPM as indicated by the
start of the red bar. Engine operation with tachometer
readings in the red area can lead to serious engine
damage.
Due to its dual-coil design, the tachometer may
not return to zero when the ignition
is turned oft: This
is
a normal condition and should not be diagnosed as
a problem in the tachometer.
TRIP ODOMETER
The trip odometer can be reset by twice fully
depressing the push button located on the right side of
the speedometer cluster. The first depression shows all
zeroes, and the second locks them in position. Both
depressions must be done to avoid possible half cycling

of the trip odometer. A slow, steady push should be
used to avoid damage to the internal mechanism.
Do not reset the odometer with the
vehicle in motion. Damage to the odometer
may occur.
The trip odometer does not affect service
procedures for speedometers listed in Section
8C.
