I have lost all electric to any outlet inside the trailer. No breaker is tripped, no fuse is blown, no GFI is tripped. The power coming into the trailer is good..I have the light on the electric heater on (so i assume it is working). I am at a loss. This is a 2013 Crossroads Zinger 30RK.
With a voltmeter, test power where your cord connects to the load center first with one probe on the black or red conductor and the other on the white one [should be about 120 volts], then move to the load side of circuit breakers [in ON position]. If you have power there and the branch circuit conductors are properly secured to them, there is open connection in the circuit somewhere. Be sure to check your branch circuit neutral [white] wires are secure in the neutral bar also.
Very often, you will find the push-in terminal on the wiring devices have lost connection!
