Electrical Systems
Battery Disconnect
(If Equipped)
Some accessories or equipment such as clocks,
radios or the refrigerator may draw small
amounts of current even when turned OFF.
A manual operated rotary switch disconnect
system allows you to disconnect either the
chassis batteries or the coach batteries or both.
Disconnecting the batteries will help reduce the
likelihood of battery discharge over long storage
periods. For your convenience, relay operated
disconnect circuits may be equipped with your
motor home. These circuits isolate selected
electrical systems from either the chassis or the
house batteries. Deactivating the relay(s) will
prevent battery discharge which may occur over
extended storage periods. During normal use of
your motor home the relays must always be in
the “on” position.
If you plan to store the motor home for an
extended period, press the disconnect switch/
es and turn off the inverter switch/es to OFF.
Remember to press the switch/es to ON when
you take the motor home out of storage
Battery Inspection and Care
Check the external condition of the batteries
periodically. Look for cracks in the cover and
case. Check the vent plugs and replace any that
are cracked or broken (if equipped). Keep the
batteries clean. Acid film and dirt on the battery
top may permit current to flow between the
terminals and discharge the battery .
To clean the batteries:
1. Wash the battery with a diluted solution
of baking soda and water to neutralize any
acid present.
2. Flush with clean water. Foaming around
terminals or on top of the battery is normal
acid neutralization. Avoid getting the soda
solution in the battery.
3. Dry the cables and terminals.
4. Do not use grease on the bare metal
inside the cable terminals to prevent
corrosion. Most greases are an insulator.
A plastic battery terminal spray will
protect the terminals after they have been
cleaned and reinstalled.
5. Keep the carrier and hold down hardware
clean and free of corrosion and chemical
accumulation.
Battery Charging
Both sets of batteries will be charged by the
chassis engine alternator and charging system
while you are driving. The DC power converter
will charge the chassis and house batteries when
plugged into 120-volt AC service or by the
generator (if equipped). If the battery needs to be
WARNING
Do not use the motor home when the chassis
batteries are disconnected. The power step will
not operate as designed if the chassis battery
is disconnected. If the step is not in the correct
extended position, you may be injured if you step
out of the motor home.
!
WARNING
Before working on either electrical system shut
OFF the Automatic Generator Start System
(AGS), generator, inverter, chassis engine
and disconnect the shore cord and negative
terminals from the batteries. If you work on the
electrical systems with these systems ON or
connected, you may be shocked, electrocuted,
or severely burned.
!
NOTE
When charging the batteries, the battery disconnect
switches must be ON.

NOTE
Power for dash radios is available from either the
chassis or house batteries. A switch on the instrument
panel allows you to select the power source. If you
use the dash radio, or other 12-volt DC equipment for
long periods of time when the motor home engine is
not running, either battery may be discharged.
