10.3.3 12 VOLT COACH FUSES
All 12-volt circuits are protected by either a circuit
breaker or a fuse in the control panel. When a
breaker trips or a fuse blows, shut off all appliances
or lights on the affected circuit and reset the breaker
or replace the fuse with a new one of the same
amperage. The label on the panel identifies both the
fuse amperage and the applicable circuit.
The fuse panel is located next to the circuit-breaker
panel, below the dinette.

10.3.4 BATTERY MAINTENANCE
Your batteries are reservoirs of 12-volt electrical
energy. Whenever energy is removed from the
battery it has to be replaced in order for the battery
to continue functioning. This energy is restored by
the engine alternator whenever the engine is
running or by the RV charging system when
plugged into a 120-volt power source.
1. Problems:
Two conditions can destroy the function of a
battery. One is called sulphating in which a
layer of sulphate crystals collects on the lead
plates inside the battery. This can happen
when a battery is stored in a discharged state.
This situation requires replacement of the
battery. The second is freezing. A battery
must be kept at almost full charge to prevent
the liquid electrolyte inside the battery from
freezing.
2. Prevention:
a. Disconnect the battery cables during long
periods of storage.
b. Hook up a battery charger at least once a
month during long periods of storage.
3. Long Term Storage:
If you do not intend to use your motorhome for
a longer period of time it might be a good idea
to remove the batteries from the motorhome
and store them in a cool dry location on a wood
or rubber pad. The batteries shoud be charged
once a month in order to prolong their life.
4. Additional maintenance suggestions:
a. Check the external condition of the battery
monthly. Look for cracks in the cover and
case.
b. Make sure batteries are always securely fas-
tened down.
c. Make sure battery clamps are tight and free
of corrosion.
Do not allow battery electrolyte to contact skin,
eyes, fabrics, or painted surfaces. The electrolyte
is a sulphuric acid solution which could cause
serious personal injury or property damage. Wear
eye protection when working with batteries.
