No 12 volt power

2018 23MRB has no 12 volt power inside trailer. Thereís 13.3 volts at front junction box. When I checked at the power converter across black positive and white negative thereís only 2.2 volts. When I disconnect the black and white wires from the converter and check across them I get 13.3 volts. To me that indicates a bad converter. I wasnít hooked up to shore power so there couldnít have been a surge. Are these converters known to fail? This is my third trailer and Iíve never had this happen.

Have you checked the reset relay (fancy fuse) out by the battery box?

The relay and 30 amp fuse both have 13.3 volts and both sides. Jayco is sending out a mobile tech. I’ll let you know what they say. I still go with a bad converter. Jayco has been very good to me in dealing with this.

Have you checked your 12V disconnect switch? Mine is in the drivers side front storage bin and I accidently turned the red key off while putting hoses away.

Happy RVing,
Jeff

No 12 volt inside trailer

This trailer didnít have a disconnect installed. I had to install one on the battery box.
