NOTE: Make sure vent caps are on securely to
prevent baking soda solution from
entering the battery and contaminating
the electrolyte fluid.
•
Clean and tighten battery terminals and have
the specific gravity checked at least once a
year.
•
Check the battery fluid level every month, or
more often in hot weather. Fill to
approximately 3/8 inch above the plates. DO
NOT OVERFILL. If fluid is added during
freezing weather, the motor home should be
driven several miles to mix water and
electrolyte to prevent freezing.
•
Fluid level check may be omitted if equipped
with maintenance-free batteries.
12-VOLT HOUSE CIRCUIT
BREAKERS
All 12-volt circuits and equipment in the
coach area of the motor home are protected by
the breaker panel. When a circuit is overloaded or
a short develops in any part of the system, a fuse
or breaker will shut down that circuit. If this
happens, turn off all affected lights or appliances
and press the breaker in to reset.
The House 12-Volt Breaker Panel is located
behind a lower cabinet door in the galley area or
beneath the bed.
A label on the panel states the amperage rating
and circuit protected for each breaker.
WARNING
Before removing any battery cables or
battery, make sure all 12-volt equipment
in the motor home is off and the power
cord has been disconnected.
Be sure to replace the battery terminal
boot back onto the positive terminal after
servicing. Care must be taken to avoid
pinching the cable between any metal
parts. Should the cable be damaged, a
short circuit could result in personal injury
or damage to equipment. Replace any
damaged cables at once. Always remove
jewelry and wear protective clothing and
eye covering when checking or handling
batteries.
WARNING
To prevent wiring damage, it is essential
when replacing the cables on the battery,
or when using a “booster” battery, that the
positive post and the positive cable be
attached and the negative post and
negative cable be attached. The posts are
marked (+) plus and (-) minus.
If a “boost charger” is used while battery
is in the motor home, disconnect both
battery cables before connecting the
charger to avoid damage to engine
electronic components.
Never attempt to charge or boost a frozen
battery.
