I have looked under the seat and i do not see the battery or the compartment please help

 

I would love to be able to help, but the companies who convert vans into camper Vans all have their own ways of doing things. You should be able to find thicker wires/ cables either black and white or black and red that go from the engine battery to an isolator and then on to the second auxiliary/ house battery.

Very likely that the previous owner took out the old failed battery and never replaced it.

Try the class B forums on Rv net for people with the fiesta camper conversion.
