When the converter receives 120 AC power, it transfers power into 12-
volt DC without any manual switches. The converter also charges the
auxiliary battery (s) when installed on the coach and is attached to 120-
volt AC power. The third function of a converter is to send 12-volt power
to the fuse panel and throughout the coach.
Each converter has a “built-in” fan which operates through a load sensor
control or temperature sensor. As more current is drawn, fan will speed
up, run faster, or slow down, based on amp draw and/or temperature.
Should the fan not run at all, the converter may overheat and will cut-out
and/or stop.
Auxiliary Battery 12-Volt DC
All travel trailers and fifth wheels are pre-built to accept a battery.
Batteries are not standard equipment, nor are they an option. To
purchase a battery, contact your dealer or battery center.
Recommended batteries are the deep-cycle type, as you need longer,
slow consuming power rather than cold-cranking power. A battery of
some type is always required for a break-away switch to function.
A battery requires routine maintenance for long life. First, terminals need
to be kept clean to avoid corrosion. Second, a battery used daily will
consume water as long as the converter is in operation, unless it’s a
“sealed battery”. Be sure to check the battery no less than every 30 days
and keep the battery filled with distilled (rain) water. When water gets
lower that the top of the plates, battery could suffer permanent damage.
Most good deep cycle batteries are NOT maintenance free.
A converter will not overcharge a battery unless a battery has a dead cell,
or the converter has a malfunction. Some types of converters have full
battery charge shut-off. Other types reduce the rate of charge as battery
conditions reach 12.7-volts DC or 1.265 specific gravity at 80°F. By
electronic standards, a battery is discharged at 10.5-volts. Dropping
voltage lower than 10.5-volts will begin damaging plates in the battery.
The interior lights will operate from the converter and/or auxiliary battery.
Some lights will have wall switches and other lights have switches in the
lights themselves.
Circuit Breakers and Fuses
—12-Volt DC
These two items have been installed in your coach to protect circuitry and
components.
Fuses
are placed into the fuse panel with the converter or into a separate
panel near the converter with access inside the coach. Fuses are placed
