(DC). While providing power to the distribution panel, the converter also charges
the 12-volt battery system.
For battery service or replacement, go to any service station or dealer who sells
and services the make battery installed in your trailer.
The converter is energized only when the trailer is hooked up to 120-volt city
power through the shoreline.

Converter Testing
The converter 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 converter
provides power to charge the trailer battery and to operate the 12-volt interior
electrical system.
On rear bed models it is located under the sofa and accessed by opening the
sofa drawer.
Front bed models have the converter installed on the front lower portion of the
pantry. Open the brown decorative door for access to 12-volt fuses and 110
volt breakers.
A. Confirm 120 volt power is going into converter.
B. Disconnect the 12+ wire from the master switch.
C. Using a voltmeter check voltage output between heavy positive and
negative wires coming out of converter.
D. The voltage must be within 13.8 and 14.0 volts. (The meter of the tester
should be calibrated periodically.)
E. If converter is not within these voltages, replace it.

The converter provides power to the 12-volt distribution panel by transforming
120-volt alternating current (AC) from the shoreline into 12-volt direct current
