12V Power Circuits

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 G 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.

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:

A.Main charge line from tow vehicle

B.Trailer Batteries

C.Converter
