    You will have to follow it out, Any relays involved having bad contacts can do this.
    Can you describe the circuit?

    Yes it's a 75amp metterbox that you plug your trailer up too.when you plug up to the box it only gets half power to the trailer, until you hook up to a battery outside then you get full power.
