CONVERTER COOLING SYSTEM
The 7300 electronic fan cooling system is the key to long life and trouble-free
operation. The fan is never on more than required to cool electronic compo-
nents in the converter. You may never hear the fan operate.
Converter
The converter transforms 120-volt alternating current (AC) into 12-volt direct
current (DC). This provides power to charge the trailer battery and to operate
the 12 volt interior lighting, fans, and appliances.
The converter is energized only when the trailer is hooked up to 120-volt city
power.
Converter Testing
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, have it serviced by a
qualified technician or replace it.
One of these wires is not spliced onto a wire of the same color. It is the back up
wire that is yellow in the cable and black in the harness.
INVERTER (option)
The Inverter powers one additional labeled 110 volt receptacle and when
combined with the factory installed television in the Audio/Video Upgrade
package this option also includes an additional invertor powered outlet for the
television.
The inverter converts 12 volt electricity from your batteries into 110 volt power.
The switch for the inverter is located under the monitor panel. Overloading the
inverter will cause a automatic shut off to activate. Removing the load will allow
the inverter to reset.
