Electrical
Systems
These circuits isolate selected electrical systems
from either the chassis or the house batteries.
Activating the relay(s) will prevent battery dis-
charge 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
to
OFF. Remember to press the switch/es to ON
when you take the motor home out
of
storage.

Battery Inspection
and
Care
A WARNING
Do
not use the motor home when the chassis battery
is
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.
Check the external condition
of
the battery peri-
odically. Look for cracks in the cover and case.
Check the vent plugs and replace any that are
cracked or broken. Keep the battery clean. Acid
film and dirt on the battery top may permit
current to flow between the terminals and dis-
charge the battery.
To
clean the battery:
1.
Be sure the vent caps are installed and tight.
2. Wash the battery with a diluted solution
of
baking soda and water to neutralize
any
acid present.
3. 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.

4. Dry the cables and terminals.
5. Do not use grease on the bare metal inside
the cable terminals to prevent
con-osion.
Grease is an insulator. Electricity will not
flow through it. A plastic battery terminal
spray will protect the terminals after you
have cleaned and reinstalled them.
6. Check the battery, including water level, at
least once a week. Keep the carrier and
hold down hardware clean and free
of
cor-
rosion and chemical accumulation .
A WARNING
Disconnect the 120-volt shore cord and the negative
terminal from the battery/ies before working
on
either
electrical system. If
you
work
on
the electrical sys-
tems with the power cord connected, you may be
shocked, electrocuted, or
severely burned.
Battery Charging
Both sets
of
batteries will be kept charged by the
chassis engine alternator and charging system
while you are driving. The DC power convelter
will charge the chassis and house batteries when
plugged into 120-volt AC service or by the gener-
ator (if equipped).
If
the battelY needs to be
charged from a different charging source, please
follow these safety guidelines:
• Leaving a charger connected to a battelY for
an extended period
of
time can shOiten bat-
tery life.
• Do not smoke near batteries being charged
or which have been.recently charged.
Please
note that batteries are being charged while
you drive, and while you are connected to
120-volt AC power through the converter/
charger circuit.
• Do not break live circuits at the terminals
of
the battery. Use care when connecting or
disconnecting booster leads or cables.
Attaching booster cables, and poor connec-
tions are a common cause
of
electrical arcs
which can cause explosion.
