Both L1 and L2 are delivering volts to the distribution box, and L1 is operating as it should. A/Cs, microwave and fireplace all work fine. Howecer, nothing work on the L2 line. Volts seem to be conming through (multimeter test), but no amps are showing up and no. outlets are working. Is there an amp setting on the Multiplus II or anyone know of any reason why this could be happening?
