Converter; Auxiliary Battery (Dealer Installed Option) - Jayco 2004 Talon ZX Owner's Manual

I
CAUTION: Your RV has many 12-volt DC loads. When combined, they total more power
consumption than is available with the 12-volt DC converter. Periodic overloads can be
handled with the additional auxiliary battery for short periods of time. It is suggested to
conserve your 12-volt DC system at most times. Prolonged overload may shorten the
performance life of converter.

Converter

A converter utilizes 120-volt AC power and transforms this energy into 12-volt DC power, which is
used inside of your sport utility trailer. 12-volt DC energy supplies power to all interior lights and
various appliances. The floor plan, and size of the sport utility trailer dictates the model and output
size of the converter required.
Inside of the converter is an electronic device which automatically switches between 120-volt AC
incoming power and battery power. An auxiliary battery as correctly installed will be charged when
the sport utility trailer is connected to 120-volt AC power. The converter will supply power through
the fuse panel located near by, possibly in the same compartment.

Auxiliary Battery (Dealer Installed Option)

All Jayco conventional sport utility trailers are designed and built to accept a battery. A deep cycle
marine type is recommended as you need longer energy rather than cold cranking power. A battery
is required to operate the breakaway switch and is also available as a source of energy when
traveling and camping.
All battery packages require an "in-line" fuse and holder attached to the battery for protection.
Maintenance on a battery is required for longer life. First, all terminals need to be kept clean and free
of corrosion. Second, a battery that is used daily or has the converter in operation will consume
water. Keep the battery filled as the cells cannot hold a charge when the water is low. A deep cycle
battery is NOT maintenance free.
In normal conditions a converter will not overcharge a battery unless (a) the battery has low or dead
cell(s), or (b) converter has a malfunction. The charging module on some converters have a positive
shut-off and on others there is a reduced charge rate to a very low amperage.
A fully charged battery will read 12.7-volt DC and 1.265 specific gravity at 80øF (32øC). A battery
is considered discharged at 11.8-volt DC by electronic standards. When the voltage drops below
these levels, permanent damage will occur.
The interior lights will operate from the converter and/or auxiliary battery. Some lights will have
wall switches and others will have switches in the fixtures themselves.
The RV battery is installed in parallel circuitry with the battery on your tow vehicle. Both batteries
supply power to your RV, so it is important not to discharge the tow vehicle battery below the level
of power required to start the engine. To prevent this occurrence while parked, you should
disconnect the wiring harness between the RV and tow vehicle or install a battery isolator (see
below). When the engine is operating with the RV connected, the vehicle's charging system will
charge both the vehicle battery and the auxiliary battery.
