and will withstand the frequent drain-and-
recharge cycles that occur under the demanding
conditions of a camping outing.
The house batteries supply power to 12-volt
equipment located in the living area of the motor
home. This includes the following 12-volt
powered components (if equipped): interior 12-
volt lighting, range exhaust fan, propane furnace
fan, fresh water pump, systems monitor panel
with water level and holding tank gauges,
refrigerator, roof vent fans, and 120-volt
electrical generator starter.
The house batteries can also provide
emergency power to start the engine if the chassis
battery is discharged. (See “Battery Boost
Switch” information in
Section 3 - Driving Your
Motor Home
).
House batteries are automatically charged by
the chassis alternator while the engine is running.
BATTERY INFORMATION
Chassis Batteries
The chassis batteries operate the engine starter
and all automotive accessories and controls
found on the instrument panel. The leveling
jacks, slideout room system and the electric step
are also connected to the chassis battery.
A battery monitor device called Trik-L-
Start
™
will help maintain the chassis battery
charge anytime the coach is plugged into 120-
volt shore power and the battery disconnect
switch is in the “On” position.
The device monitors battery voltage in the
house batteries and compares it to the chassis
battery. If the device senses the chassis battery
voltage is approximately ½ volt lower than the
house battery, it allows up to 5 amps of current to
flow to the chassis battery.
The circuitry within the device prevents back
feeding of electricity from the chassis to coach
battery so if 120-volt power is interrupted, the
chassis battery will not be discharged.
House Batteries
The house batteries supply current to 12-volt
equipment located in the living area of the coach.
This includes interior lights, range exhaust fan,
furnace fan, water pump, water level and holding
tank gauges, 120-volt generator starter,
refrigerator and bath roof vent fan. The house
battery may also be used to start the engine if the
automotive battery is discharged. (See “Aux.
Start Switch.” or “Battery Boost Switch” in
section 3.)
The house batteries are automatically charged
by the chassis alternator while the engine is
running.
AUXILIARY BATTERY
DISCONNECT SWITCH
The Aux Battery Disconnect switch
disconnects the house (auxiliary) batteries from
the 12-volt system of your coach during storage
periods to avoid battery drain by electrical items
that are hooked directly to the house batteries,
such as clock displays and radio memories, etc.
Always leave this switch ON while using the
coach.
NOTE: Some electronic displays and memory
functions may need to be reset after
power has been reconnected.
See also “Battery Care” elsewhere in this
section.
BATTERY ACCESS
The batteries are located on slide-out trays in
the battery compartment on the outside of the
coach.
