RT770E OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
Low Fuel Level
The Low Fuel Level Indicator (27) (Figure 3-6) illuminates
when the fuel level in the tank is nearing empty (15%). When
this indicator comes on fuel should be added to the fuel tank
immediately. The light will go out when the fuel tank level
reaches 20% of capacity.
Battery Charge Indicator
With the engine running, the Battery Charge Indicator (28)
(Figure 3-6) illuminates red if battery system voltage is below
nine (9) volts, engine ECM voltage is below (9) volts, or there
is no alternator charge signal present.
If the engine is running and the Battery Charge Indicator
illuminates, investigate possible alternator, alternator fuse, or
alternator wiring problems.
When the engine is not running and the Ignition Switch is in
the ACC or RUN position, the Battery Charge Indicator turns
on to indicate the batteries are being drained and not being
charged.
Voltmeter
The Voltmeter (battery gauge) (29) (Figure 3-6) is located in
the steering column gauge display. The Voltmeter indicates
the voltage being supplied to or from the batteries and has a
scale of 8 to 18 volts.
If the Ignition Switch is in the ACC or RUN position and the
Voltmeter indicator is in the red, the batteries may need to be
recharged or possibly replaced.
Tachometer
The Tachometer (30) (Figure 3-6) is located in the steering
column gauge display. The tachometer registers engine rpm
and is calibrated in rpm x 100 with a range of zero [0] to 35.
The tachometer receives a signal from the engine ECM.
