Not sure of your particular model but most TT lights are 12volts. With your battery hooked up and charged you should not have to do anything but turn on the switch. Sometimes there will be one regular lamp installed and that would require being plugged into shore power. The frig should have two button probably over the door. It also will require 12 volts from the battery to work even on gas only. Should have the option for Auto/Gas and On/Off if I remember right. If you don't have AC power (shore power) in the Auto selection it should switch over to run on gas. Be sure you have your tank on and the lines will have to bleed of the air before the pilot will light. Without seeing your setup it's hard to give specific directions but someone with your model trailer will probably chime in directly.....

First, are you getting any power when on 12 volts?

If there is a dummy light on the converter, check to see if its lit to see if you have any power to the camper when on batteries (The area below my fridge where the converter and fuses are has a light that will always be lit when powered by batteries or AC).

Assuming that is lit while on batteries and still no lights, I would check fuses and then your light fixtures (with a multimeter) for current, and then the bulbs. Unlikely that all of the bulbs are bad but who knows.

Your water pump will work on battery.
