Thanx Craig for your reply. Maybe I was bit hazy in my problem. I'm good about the Dometic's operation, and it is all good when I bench tested in the garage. I'm ready to reinstall and was checking the 12v wiring in the van and found the problem I described. I checked all the circuits with the a) ingnition off, b) ignition on, and c) with the engine running. I don't have power to the relay accept from Bat at term 87. Is this supposed to this way? Seems like there ought to be power to the #12 wire coming into term 85 which connects to the ignition switch. Hope that helps to de-fog my delema. Thanx for any help! Rick Foster 85 westy "Cassidy"
Now I'm stumped and stymied with getting back on the road with my Dometic working. It never has, but with help of Lorean and Ken, I took it out, refurbished it, bench tested each system and it worked. Before putting it in, I tested the 12v input and here's what I've got: 1- no auxillary battery, just stock wiring to'refrigerator heater relay'(bently 97.32.e), plan to put in aux bat in future. 2- clean wiring from relay thru fuse block and to ignition switch. 3- + Power from bat at term 87 thru term 30 to frig connection. 4- continuity in blue wire from term 87 to D connection at the alternator. 5- No Power at term 85 from the ignition switch but + continuity thru this wire to the ingnition terminal (term 50). This term is coupled with a #10 wire that goes I know not where. Bently (97.62) looks like it's track 78, but it looks like it goes off where 'no man has been before'! I can't read any 'track 78' anything functional and I'm not spark engineer. Spock where you!

If you have the fridge completely off and turn it onto 12 v and drive for 2+ hours, you'll feel the fins getting cold. If you just drove around town....i wouldn't expect much of anything. The 12v selection is really just to keep things cold while driving
