I have a circuit that runs nine recessed lights and a few oulets and two switches for outdoor lights. Last week I plugged a heater into one of the outlets and the outlet stop working. The recessed lights are first on the circuit and still work, but the two outlets and two lights switches are not working. I have tested the voltage in the outlets and I am getting a reading of 3 volts. I have taken all of the boxes apart and everything is conected correctly. When the hot and ground are tested I am getting 120 volts. When the hot and neutral wires are tested I am getting 0 volts. Something happened between the last recessed light and the first light switch that I can't figure out. Any help would be greatly appreciated.
