I have a 2002 Damon Ultrasport with no power to the slides, refrigerator or the front AC. There must be a fuse or relay somewhere that is not working. Any help would greatly be appreciated.

Is the Salesman switch (usually by the entry door) “On”?

How good are your house batteries?

House batteries provide power for A/C thermostat, refrigerator, slides.

Slides are usually 12VDC; RV refrigerator (not residential) 12VDC control; AC - local control or thermostat? If local control it's an 120VAC issue.

Do your interior lights work?

House batteries good, salesmen switch in correct position. I’m thinking I have a grounding issues.

All the 12v lights are working fine. I ran a wire from the house batteries to the refrigerator control ground and there was no change. I ran a wire directly from the house batteries hot to the refrigerator control and got the refrigerator working. Does that disprove my grounding issue theory?

Running the wire from +battery to the refrigerator control and the fridge started working - sounds like your ground is good.
Check the latching solenoid that transfers power via switching the Salesman switch.
One side of that solenoid is the house batteries. The other side is the coach. If that solenoid isn’t latched, then you’ll see 12volts on one side, and nothing on the other.

This assuming you have somehow load tested the house batteries as a discharged battery can easily read +12volts when measured using a digital or even an analog voltmeter.

If there is 12 volts either side of the solenoid, then follow the battery cable looking for an inline heavy fuse or circuit breaker. On our coach, it’s chassis mounted stand-alone fuse.
