2018 X23B No power on battery - Shore works

[NaughtyNurse9]

Hey all - recently picked up a 2018 X23B Pop out. Shore power works fine but off shore and trying to run on battery there is absolutely zero power. Brand new battery pulling 13V - checked all fuses 30 AMP was blown so I replaced that but still no success. The lift/hitch only works when plugged into the truck or shore power. Past that I have checked the ground connection from the battery to the frame and it seems good. Trying to pull a voltage from + terminal to frame is spotty. Could really use some help here as a $10k paperweight is not the best option for camping. Thanks all in advance.

There should be a couple of 30 amp fuses in the panel that are seperate from the regular 15 amp array. One will be a reverse polarity fuse that will blow if the battery is connected backwards, even for a split second.

If your trailer has the typical square metal junction box on the frame, check all the connections inside. It's not even close to waterproof, and connections will be by household wire nuts, and can corrode and/or loosen up. Just a couple of thoughts.

I saw a repair video once that showed a few circuit breakers mounted on the back side of the steel frame under the front of the TT. Follow the wires using a voltage meter.

There also should be an inline fuse near the battery. If it is not right at the battery, follow the charge wire back to where it connects to the 7 pin wire harness. It to should be a 30 amp fuse.
