Your tow vehicle provides 12 volts through the 7 pin trailer connector.
It goes directly to the battery, possibly through a fuse or circuit breaker.
From there it goes to a fuse panel inside your TT (travel trailer).
The fuse panel then distributes 12 volts to different appliances.
The TT battery may have a disconnect switch mounted near the battery. If it is "off", the TT battery will not supply power, nor will it recharge.
There also may be a fuse or circuit breaker near the battery. It may prevent the battery from supplying power or charging.
When you are plugged into shore power, the converter in your TT converts 120 volts AC to 12 volts DC.
The output of the converter goes to the fuse panel like the 7 pin hitch connector.
The converter also charges the battery.
If a disconnect switch near the battery is "off", it will not charge.
I wish you good luck and happy trails ahead!
