I pulled out the converter and opened it up. It has a 25amp fuse inside. The fuse was good and I tested it just to make sure.
It was full of dust, so I blew it out with air compressor.
Reinstalled and still no voltage on the DC side.
Ordered a new converter. SHould be here Monday.
quick question... the trailer batteries were charging while driving..
I'm not sure how it could charge while driving, but not while plugged into 110? Does the 12 volt from the tow vehicle not go through the converter before charging the batteries?
