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 DC by electronic
standards; 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.
Battery storage instructions
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 OEM instructions.
When it is time to replace the auxiliary battery,
replace it with a Group 27 deep cycle battery
only. Contact the battery OEM 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 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).

purchase and installation of this aftermarket

The 12-volt fuse panel is labeled to indicate
the fuse sizes, positions and components
powered. At the beginning of camping
season, inspect all the 12-volt fuses and
replace as needed.
Replacing a fuse
Before replacing a fuse, always turn OFF the
electrical component(s) protected by it.
1. Disconnect the power cord.
2. If so equipped, disconnect the auxiliary
battery negative cable at the battery.
3. Remove the fuse panel cover to check
fuses.
4. Pull the fuse straight out of the fuse block.
If the fuse is not blown, something else
Replacement fuses must be of the same
voltage, amperage rating and type. Never
use a higher rated replacement fuse; doing
so may cause a fire by overheating the RV
wiring.
