Electrical System Operation
Coach Batteries (12 Volt DC Power
Supply)
The coach batteries supply power to all the
12 volt DC lights and equipment in the living
area of your motorhome. This includes the roof
vents, refrigerator (when operating in 12 volt
DC mode), 120 volt AC generator starter, water
pump, furnace fan, interior lights, holding tank,
water level gauges, etc.
Coach Battery Condition Meter
For voltage readings, refer to Magnum Inverter
Remote Control Status display (2).
Battery Maintenance
Automotive batteries store chemicals that
react and convert chemical energy into
electrical energy. Whenever electrical energy
resources are used, the battery drains and
becomes discharged. Applying current to the
batteries using the engine alternator (when the
motorhome’s engine is running) or by using
the motorhome inverter/charger will recharge
the batteries and enable them to continue
functioning normally.
Battery Problems
Several conditions can destroy the battery’s
function including sulfation and freezing
Sulfation occurs when lead sulfate crystallizes
and deposits on the negative plates inside the
battery. This condition is caused when a battery
is deprived of a full charge for an extended
period of time (30 days or more, especially
during warm weather). If sulfation occurs, you
will have to replace the battery.
Freezing can discharge, damage, or destroy
a battery. Batteries must be close to fully-
charged to prevent the liquid electrolyte inside
the battery from freezing.
Long-Term Storage
Turn off the battery disconnect during extended
periods of storage. Hook up a battery charger
at least once a month, or connect the 120 volt
AC shore line to a suitable power source.

NOTE: If storing your motorhome for an
extended period of time and batteries
cannot be routinely charged, it is advised
to remove the batteries and store them in
a cool, dry location. Do NOT store batteries
on a moist concrete floor. If batteries are
not recharged routinely while in storage,
ensure batteries are fully recharged prior to
reinserting batteries into your motorhome.
