There are more than one power source and over current protection devices. Is this an HWH system? You should have an electrical compartment for the chassis at the rear of the coach where there are relays, fuses and circuit breakers. Also probably a panel in the center of the coach, basement compartment behind an access cover. HWH will also have a control box with fuses behind a clear plastic cover. Does the system touch pad light up?
