ELECTRICAL
AUXILIARY BATTERY (AUX
BATT) SWITCH
The AUX BATT switch disconnects the
auxiliary (coach) batteries from the 12-volt
system of your coach to avoid long-term battery
drain by electrical items that are hooked directly
to the coach batteries, such as clock displays and
radio memories, etc.
Always leave this switch ON except when the
vehicle is not in use.
Some electronic displays and memory
functions may need to be reset after power has
been reconnected.

HOUSE BATTERY ACCESS

The house batteries are located in a compart-
ment in the floor directly behind the driver seat.
Twist the lock and lift the cover off to access.

BATTERY CARE

Lead-acid type batteries are electro-chemical
devices for storing and releasing electrical
charge. As such, they are simply an electrical
reservoir, not an electrical source. As soon as
energy is removed from the battery, it should be
replaced by the engine alternator or the RV
converter system.
If a battery sits unused for 30 days or more,
especially during warm weather, it can develop a
deposit of sulfate crystals on the metal plates
inside the battery. This condition is called
'sulfating' and prevents the battery from either
releasing or accepting a charge. If this condition
occurs, the battery must be replaced.
If a battery does not contain at least 80%
charge during freezing temperatures, the
electrolyte can freeze and crack the battery case.
The two best defenses against sulfating and
insufficient charge are to:
1. Turn off the AUX BATT switch to avoid
parasitic discharge (the trickle discharge
caused by directly connected components like
LP gas leak detectors or digital clock displays,
etc.).
2. Check the battery and recharge as necessary at
least once a month during long storage
periods. Turn the Auxiliary Battery switch off
to avoid electrical arcing when attaching or
detaching charger clamps.
WARNING
California Proposition 65 Warning:
Battery posts, terminals and related
accessories contain lead and lead
compounds, chemicals known to the
state of California to cause cancer and
reproductive harm. Wash hands after
handling.
NOTE: We do not recommend leaving the
shoreline plugged in continuously during
storage periods because the batteries can
lose electrolytic fluids and become
