DC system is composed of components that
will operate when the following conditions are
met:
0
Power is supplied by the tow vehicle
alternator when the engine is running and
the 7-way trailer plug is connected. This
powers the RV’s running lights, brake
lights, turn signals and brakes. In addition,
the 7-way trailer plug provides a common
ground and a 12-volt charge line to charge
the auxiliary battery (the J/Trax is not
equipped with a factory installed charge
line).
0
The converter will supply interior 12-volt
DC power when the power cord is plugged
into campground power. The converter will
also charge the auxiliary battery in most
situations (excludes J/Trax models).
0
The auxiliary battery powers many interior
12-volt components including the lighting
fixtures, water pump, 12-volt motors,
12-volt appliances, etc. It also powers the
breakaway switch.
In addition to the 12-volt DC system

Your RV has many 12-volt DC loads. When
combined, their total is more than the
converter can produce. High demands for
12-volt power can be met by an auxiliary
battery for limited periods of time. The 12-volt
DC electrical system is designed for usage
with a Group 27, deep cycle battery.
Dry camping
Consider the charge condition of the auxiliary
battery when dry camping. If the auxiliary
battery is not being recharged and power is
being drawn from it, it will eventually
discharge. The battery will discharge at a
faster rate as its energy level becomes
depleted. It is recommended you plan your
electrical usage accordingly.
A fully charged auxiliary battery will read 12.7
volts DC and 1.265 specific gravity at 80°F
(32°C). The auxiliary battery is considered
discharged at 11.8 volts DC by electronic
standards. When voltage drops below those
levels, permanent damage may occur.
Typically, a deep cycle battery has an
amp-hour rating of 75-100 amps. If you run the
furnace and refrigerator simultaneously, you
will be using approximately (12.0 + 3.0) 15.0
amps per hour. This does not include any
12-volt lights, water pump or any other 12-volt
component.
If the furnace and refrigerator in the
above example operated constantly, a
75 amp-hour battery would become
fully discharged in 5 hours (75ah / 15a
= 5h).
For accuracy, test the auxiliary battery voltage
using a volt-ohm meter (customer supplied).

Approximate Electrical Load Rating.
The auxiliary battery should be installed in
parallel with the battery in your tow vehicle.
When the 7-way trailer plug is connected, both
batteries power the RV so it is important not to
discharge your tow vehicle battery below the
level required to start the engine. To prevent
this from occurring, disconnect the 7-way
trailer plug or install a battery isolator. When
the tow vehicle engine is operating with the RV
connected, the tow vehicle charging system
will charge both batteries.
