MONITOR PANEL (FIGURE 8)
DESCRIPTION
The MotorHome Monitor Panel is a series of four
gauges located at eye level in the living area . In-
cluded are:
* LP GAS - This gauge is designed to indicate
the amount of liquid petroleum gas remaining in the
tank .
BATTERY VOLTS - Indicates living area
battery voltage. During operation, the indicator
should remain in the center segment of the dial to
indicate normal battery condition. If the indicator
shows less than 11-volts, an under-charge condition
exists in the living area battery and a recharge is
required.
For information regarding batteries and charging
procedures, refer to ENGINE ELECTRICAL, Sec-
tion 6Y.
* WATER TANK - This gauge is designed to
indicate the amount of water remaining in the living
area water tank.
* HOLDING TANK - This is designed to indi-
cate content level in the holding tank . Never allow
this gauge to reach the "FULL" mark . If the holding
tank is overfilled the overflow will back up through
the bathroom shower drain.
