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 applianc-
es 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 identifi es
both the fuse amperage and the applicable circuit.
The fuse panel is located next to the circuit-break-
er panel, below the refrigerator.

10.3.4 BATTERY MAINTENANCE
Automotive 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 en-
gine 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 bat-
tery. The second is freezing. A battery must
be kept at almost full charge to prevent the
liquid electrolyte inside the battery from freez-
ing.
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
Do not allow battery electrolyte to contact skin,
eyes, fabrics, or painted surfaces. The elec-
trolyte is a sulphuric acid solution which could
cause serious personal injury or property dam-
age. Wear eye protection when working with
WARNING
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
fastened down.
c. Make sure battery clamps are tight and
free of corrosion.
