Check battery cut off switch if you have one. Check two 40A fuses in converter. They are usually orange in color. They will blow if the battery is very low and the unit is connected to shore power or if the battery is connected reversed. Do any of the 12V things work ( ie all lights are 12V)? Power in the Tracer is either 120V AC for AC, microwave and some dual mode devices ie fridge) or 12V for lights, and control circuits for AC, fridge, furnace, slide, and awning. Also check to insure that the breakaway cable has not pulled out the pin.
