ELECTRICAL SYSTEM
During the winter the batteries should be removed from the trailer and stored in a cool,
dry place, where there is no danger of freezing. It should be kept full of water, cleaned
and charged monthly. A battery that is allowed to completely lose its charge will never
regain its original power or a full charge.
For battery service or replacement, go to any service station or dealer who sells and
services the make battery installed in your trailer.
When being towed, the 12-volt batteries in your trailer are receiving a constant charge
from the tow vehicle’s generator or alternator through the seven-way connector.
Your tow vehicle’s voltage regulator controls the charge rate. It is important to keep the
seven-way connector clean. One method is to use “Spra-Kleen”.
Whenever possible use the automatic built in charge of the converter system for charg-
ing. The charging circuit automatically controls the current, reducing it as the batteries
increases in charge.
At service stations make certain they give your batteries a slow charge because quick
charges will drastically shorten the life of the batteries, as will allowing repeated com-
plete discharges.
GLASS MATT BATTERIES (Optional w/Solar Panel Charging System)
In AGM sealed batteries, the acid is absorbed between the plates and immobilized
by a very fine fiberglass mat. No silica gel is necessary. This glass mat absorbs and
immobilizes the acid while still keeping the acid available to the plates. This allows a
fast reaction between acid and plate material.
Battery Maintenance is an important issue. The battery should be cleaned using a
baking soda and water mix; a couple of table spoons to a pint of water. Cable connec-
tion needs to be clean and tightened regularly.
Battery Storage:
The following recommendations may be helpful if the battery is to be stored:
· When storing the battery in a vehicle or vessel, it is not necessary to leave it on
charge. Disconnect the negative battery cable. This will prevent inadvertent discharg-
ing of the battery that may lead to a complete discharge.
Fully charge the battery before putting it in storage and store in a cool place.
· Boost charge the battery every 2 to 3 months to ensure maximum battery life.

The converter/charging system is the interior low voltage electrical system that enables
you to use the interior lights, fans, pumps and 12-volt appliances whether operating
on self-contained battery power or 120-volt city power. The 12-volt light bulbs give off
the same light as regular household bulbs, so that when operating on self-contained
battery power, everything works normally except the 110-volt convenience outlets and
110-volt appliances. The converter system is designed to maintain constant output
voltages regardless of the variances that occur in city power systems.
12V POWER CIRCUITS
The current in the converter system is 12 volts direct current (12VDC) negative
grounded. Power sources that supply 12VDC current to the system are as follows:
