SECTION 6
ELECTRICAL
To ensure that the battery will always accept
and hold a charge, follow these simple
maintenance practices.
•
Make sure the batteries always remain
securely clamped in the battery tray.
•
Make sure battery cable clamps are tight on
the terminal posts and are free of corrosion.
•
Neutralize corrosion buildup or acid film on
top of battery by washing with a baking soda/
water solution. Rinse with clear water.
NOTE: Make sure vent caps are on securely to
prevent baking soda solution from
entering the battery and contaminating
the electrolyte fluid.
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.
•
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.

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.
12-VOLT HOUSE FUSES AND
CIRCUIT BREAKERS
All 12-volt circuits and equipment in the
coach area of the motor home are protected by
either a fuse panel or 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 reset the breaker
or replace the fuse with a new one of equal
amperage rating.
