For accuracy, test the auxiliary battery voltage using a volt-ohm meter (customer
supplied).
A fully charged auxiliary battery will read 12.7 volts DC and 1.265 specific gravity at 80°F
(32°C). The auxiliary battery is considered discharged at 11.8 volts, and dead at 11.65
volts.
When voltage drops below those levels, permanent damage may occur. Typically, a deep
cycle battery has an amp-hour rating of 75-100 amps.
If you run the furnace and refrigerator simultaneously, you will be using approximately
(12.0 + 3.0) 15.0 amps per hour. This does not include any 12-volt lights, water pump or
any other 12-volt component.
If the furnace and refrigerator in the above example operated constantly, a 75
amp-hour battery would become fully discharged in 5 hours (75ah / 15a =
5h).
The auxiliary battery should be installed in parallel with the battery in your tow vehicle.
When the 7-way trailer plug is connected, both batteries power the RV so it is important
not to discharge your tow vehicle battery below the level required to start the engine. To
prevent this from occurring, disconnect the 7-way trailer plug or install a battery isolator.
When the tow vehicle engine is operating with the RV connected, the tow vehicle charging
system will charge both batteries.
Replacement and maintenance
Some equipment in your RV will draw small amounts of current even when turned OFF.
To prevent the auxiliary battery from being discharged when your RV is not connected to
shore line power, disconnect the auxiliary battery negative cable at the battery. During
storage, it is important to check the voltage monthly and recharge the auxiliary battery as
needed. If you remove the auxiliary battery from your RV, store it in a dry, cool area per
the manufacturer’s instructions.
When it is time to replace the auxiliary battery, replace it with a Group 27 deep cycle
battery only. Contact the battery manufacturer for further information. Do not reverse the
positive and negative battery cables (doing so will blow the reverse polarity fuse(s) that
protect the converter).

You may want to consider the installation of a battery isolator on your tow vehicle as a
convenience feature:
It receives current from the tow vehicle alternator and controls distribution of energy
to both the RV auxiliary battery and the tow vehicle battery.
It serves as a check valve to prevent energy from being drawn from your tow vehicle
chassis battery (so you can start your tow vehicle engine).
Your dealer can assist you with the selection, purchase and installation of this aftermarket
part. than 60 watts (5 amps) of 12-volt power. To prevent short circuits do not allow
metallic foreign matter to get into the 12-volt DC outlet.

The Load Center contains 12VDC fuses and 120VAC circuit breakers for almost all of the
electrical appliances and circuits in the RV. The 120V Main Breaker (if so equipped) is
located in this panel and will turn off all 120-volt power to the recreation vehicle. The
load center is a hinged panel typically attached to a cabinet face in the main living area.
Locations will vary by model. Refer to the
diagram inside the Load Center for specific
fuse assignments. Most load centers contain the same components, but they may be
positioned differently. Not all load centers will include a main breaker.
