10. When replacing batteries, make sure the new battery is
the same type and rating of the battery that was originally
equipped with your motorhome. If in doubt, consult
your RV dealer for advice on battery replacement.
NOTES:
• Only use distilled water when filling battery cavities.
Be careful not to overfill battery cavities and never
move or travel with a battery that is uncapped.
• Use a battery terminal conditioning spray (avail-
able at auto parts stores) to prevent battery termi-
nal corrosion.
Battery Storage
To prevent coach battery discharge when the motorhome is
not connected to power through the shore line power cord,
turn OFF the main battery switch and disconnect the negative
battery cable at the terminal.
If the motorhome is connected to power through the shore
line power cord, it is recommended the main battery switch
be left ON (do not disconnect the battery(ies). This will allow
the converter, inverter (if so equipped), or solar panel (if so
equipped) to trickle charge the coach battery(ies).
Battery Replacement
WARNING
WARNING
TO PREVENT HAZARDS FROM DANGEROUS
BATTERY GASES:
If replacing or adding additional batteries to the 12 volt
electrical system, ensure batteries are always located
in a well-ventilated area and separated from the living
space of the motorhome.
When replacing batteries, make sure the new battery is the
same type and rating of the battery that was originally equipped
with your motorhome. If in doubt, consult your selling dealer
or a qualified RV technician for assistance. Always re-connect
the battery cables in the original factory-installed positions.
•
Do not replace a deep cycle battery with a starting bat-
tery. Only use deep cycle batteries for your motorhome's
coach application.
•
Do not replace your chassis, or starting battery with a
deep cycle battery. A starting battery is designed to deliv-
er higher instant amperage, needed to start the vehicle's
engine.
•
Check to be sure the replacement battery will fit the
battery tray of your motorhome. Group 24 batteries are
physically smaller than Group 27 batteries.
Inverter (standard)
CAUTION
CAUTION
The standard inverter installed in your motorhome is
not rated to supply the electrical energy for the roof
air conditioner. Use shore power or generated power
(from the generator) to power the roof air conditioner.
NOTICE
NOTICE
Inverters are rated in wattage, which is the maximum
electrical energy they can deliver. Do not attempt to
operate higher electrical loads than the inverter is
designed to supply.
Your motorhome is equipped with a factory installed inverter
that converts 12 volts DC, supplied by the auxiliary battery(ies),
to usable 120 volts AC. It provides continuous AC power to
appliances, entertainment devices, and select circuits. Use the
inverter to power small 120 volt AC appliances when shore
power is not available and when operating the generator is not
permitted or feasible.
A remote panel may be installed that duplicates the ON/OFF
power switch and other functions located on the front panel
of the main unit. In addition to the power switch, the remote
panel features a green power status LED. The inverter should be
turned OFF when the motorhome is in storage.
NOTE: Inverters that are factory supplied with the
optional Re(li)able Battery Power System have a
higher output wattage rating as compared to the
standard inverter. This higher wattage unit is capable
of supplying enough energy to operate the coach air
conditioner and other 120 volt AC appliances.
Inspection and Maintenance
If the inverter is not functioning check both the circuit breakers
protecting the inverter input, and located on the inverter. There
are no customer serviceable parts inside the inverter case and
the manufacturer's warranty will be void if the case has been
opened. The inverter's cooling fins and the cooling fan should
be kept clear of any obstructions. If you have further concerns
contact your dealer or TMC Customer Care.
