Battery storage instructions

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 at
least every two weeks and recharge the
auxiliary battery as needed. If you remove the
auxiliary battery from your RV, store it a dry,
cool area as per its OEM instructions.

Replacement and maintenance

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 fuses that protect the
converter.

You may want to consider the installation of a
battery isolator on your tow vehicle (customer
installed) 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).
Your RV dealer can assist you with the
selection, purchase and installation of this
aftermarket part.

Replacing a fuse

WARNING
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 over heating the RV
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 RV dealer for further
assistance.
5. Insert a new fuse of the same specified
voltage, amperage rating and type in the
original location. Never use a higher
rated replacement fuse.
The fuse panel label should be kept
permanently affixed to your RV. The fuses will
not offer complete protection of the RV
electrical system in the event of a power surge
or spike.
