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
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 park trailer 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 park trailer connected,
the tow vehicle charging system will charge
both batteries.
Replacement and maintenance
Some equipment in your park trailer will draw
small amounts of current even when turned
OFF. To prevent the auxiliary battery from
being discharged when your park trailer 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 park trailer, 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).

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
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
park trailer wiring.
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
must be causing the problem. Please
contact your dealer for further assistance.
