First I would check the output of the convertor while plugged into city power. If nothing check the input side of the convertor to be sure it has power. If it has power but no output check any fuses that may be on the convertor.

Once you have output from the convertor check the trailer battery voltage. If you have both convertor output and battery voltage check the 12volt fuses or circuit barkers. I suspect the problem is before the fuse/barkers as it is highly unlikely that ALL would fail at the same time.

Do you here a hum? The univolt converter for the 12 volts has a hum to it. There are also fuses for the battery. A positive and a negative fuse. On my 69 tradewind the converter is in the curbside rear compartment. The battery and fusebox are in the rear hatch above the rear bumper.

Look for a fuse on the negative side of the circuit as well as the positive side. Can you hear the Univolt humming? Make sure all of the fuse holders are holding the fuses tight. Also, if the fuses are old. The element may have become disconnected from the end cap of the fuse. It may be best just to replace all of the fuses with new. Down the road you may want to consider replacing the Univolt with a more modern 3 Stage Converter.

This recently happened to me also (no 12 volt power). The connection between the battery ground terminal and wire was corroded. It looked good from the outside, but the wire had isolated itself from the clamp and without a ground to the battery no 12 volt systems will work.
