Water Temp; Voltmeter; Air Pressure Gauge - Monaco DIPLOMAT 2004 Owner's Manual

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 uses fuel
from main tank and will affect fuel mileage figures. Diesel
Generators will not operate below 1/4 tank to ensure there is
enough fuel to run main engine.

6. WATER TEMP:

Under average conditions the gauge will read between 180° F and 205° F.
Monitor this gauge frequently when CLIMBING HILLS, TOWING OR
IN HIGH AMBIENT TEMPERATURES. If the gauge shows that an over-
heating condition exists (the needle moving above the 212° F area)
IMMEDIATE ACTION should be taken to avoid engine damage.
Overheating may be a result of any of the following conditions:
• Low coolant level.
• Mechanical failure of hoses or belts.
• Blocking of charge air cooler fins.
• Climbing a long hill on a hot day.
• Towing a heavy trailer.
• Idling for long periods of time.

7. VOLTMETER:

Shows the charge condition in the chassis battery. The normal voltage
with the ignition switch ON and the engine OFF varies between 12.0 and
13 Volts. With the engine operating without a heavy load, the battery
charging voltage is about 14.0 Volts. Battery readings of less than 10.5, or
more than 15 Volts, usually indicates a battery or electrical system
problem.

8. AIR PRESSURE GAUGE:

Uses two needles to indicate air system pressures. One needle
indicates air pressure of the front air tank. The other needle indicates air
pressure of the rear air tank. The normal air system operating pressures
are 105 to 120 psi. These air pressures are preset at the factory. If a
problem occurs with either air system not maintaining normal operating
pressure, it is an indication of a malfunction in the air system. Use caution
and stop the motorhome in a safe area. Contact a qualified technician
immediately.
NOTE: It is not safe to drive the motorhome with low air
pressure. Damage can occur to the suspension, drive shaft
and can also affect operation of the air brake system.
