Open circuit found - problem fixed!
Your suggestion to "Check your bedroom closet for a fuse panel" was the helpful suggestion. [I had already checked the circuit breakers from the front side]. My panel is located under the bed. Getting to the back side of the circuit breaker box, I found the other end of the wire bundle from the kitchen side EMS that lacked 12 vdc. I saw it was connected to a daughter p.c. board labeled 4L64 of the Energy Management System that wasn't working in the kitchen. Good so far. This board should have had 12 vdc on pin 1 of J4, but didn't, so the whole board was dead. Going upstream, I found a crimped lug to a nearby spade terminal disconnected behind a 15 Amp 12 vdc circuit breaker marked "Monitor/TV" that was connected to a buss bar at 12 volts. I initially overlooked this disconnected (and mislabeled) wire until I realized that this was my problem and connected the spade to the nearby lug terminal and voila, everything worked! The lug had probably worked its way off the terminal during the rough ride on an Indianapolis, IN side street into our present campground. I lengthened the loop of wire and firmly tied it down nearby with a nylon tie so it won't come loose again. And I ordered your suggested "tone generator" for the tool box for the next event where wire tracing is called for. Thank you for the two good suggestions and the encouragement that help lead me to a successful repair!
