fifth wheel front landing legs

[wayne1234]

My son in law has a fifth wheel and the front legs won't work on the twelve volt battery but will once the trailer is plugged into 110volts they work. Can anyone tell me what to check for.
Thanks,
Wayne

Legs should come straight off the battery. Look around the battery for a fuse or circuit breaker. Some circuit breakers have small reset button.

What he said. Legs run on 12v power so the motors not getting power until you plug in. $ to a donut it's one of the two or a bad ground from the motors negative wire.
