Gauges
3-IN-1 GAUGE:
9. TACHOMETER (0-4K RPM) - Displays engine speed in revolutions per minute
(RPM).
10. FUEL GAUGE - Fuel gauge will register approximate fuel level in tank, when ignition
switch is in run position.
NOTE:
Fuel mileage varies with driving style and road conditions. Always average more than
one tank of fuel to obtain a more accurate figure. The diesel generator and the Aqua-
Hot system both use fuel from main tank and will affect fuel mileage figures. Diesel
generator and Aqua-Hot will not operate below ¼ tank to ensure there is enough fuel
to run main engine.
11. VOLTMETER (10-18 V) - Shows the charge condition in the chassis battery. The nor-
mal voltage with the ignition switch ON and the engine OFF varies between 12 and 13
Volts. With the engine operating without a heavy load, the battery charging voltage is
about 14 Volts. Battery readings of less than 10.5 Volts, or more than 15 Volts usually indi-
cates a battery or electrical system problem.
4-IN-1 GAUGE:
12. ENGINE OIL PRESSURE (0 - 120 PSI) - Indicates oil pressure, not the amount of oil
in the engine. Please refer to manufacturer's instructions for specific pressure recommen-
dations.
