tmw188 Posted June 8, 2021 Share Posted June 8, 2021 Trying to find the solenoid location for the House Disconnect switch? I haven’t gone to the coach yet to look but I’m thinking it’s in the right rear access door area? The switch itself inside the door is good but it is not turning the 12v house power off. It’s not the same as the Battery Isolator in this pic is it? Link to comment Share on other sites More sharing options...
Dr4Film Posted June 8, 2021 Share Posted June 8, 2021 Nope, it is the solenoid directly below that one and it's labeled Battery Cut-Off Relay. Frankly I would strongly suggest that you bypass the damn thing as they are a high failure item. SO if you replace it chances are that one will fail also some day. Many people including myself have bypassed the relay and we no longer have to worry about losing 12 VDC power to many of the house devices at the worst possible inconvenient time.

vito.a Posted June 8, 2021 Share Posted June 8, 2021 It's in the front electrical run bay outside just below the drivers feet. Link to comment Share on other sites More sharing options...
tmw188 Posted June 8, 2021 Author Share Posted June 8, 2021 Perfect thanks that’s the other place I was going to look. I hear nothing when I turn it on or off. In my other coach it was a distinct clunk. Link to comment Share on other sites More sharing options...
Mark B Posted June 8, 2021 Share Posted June 8, 2021 I have the same coach and have also replaced that relay. If it fails again I will do as DrFilm has done and just bypass it. Link to comment Share on other sites More sharing options...
tmw188 Posted June 8, 2021 Author Share Posted June 8, 2021 Nice. Have you by chance replaced any of your switches? I just ordered 6 new of the red indicator lights most of which for the wtr pump. But the switches are small and will take awhile to get use to there locations. Bezels are old and brittle too. Link to comment Share on other sites More sharing options...

Vito, His coach is a 2002 Windsor and they put all of what is in the photo inside the RRB on the passenger side. Todd, I replaced a lot of the small 12 VDC switches with Carling Technology small 12 VDC switches which are better built and smoother to operate than what came on the coach from the factory. I also replaced all of the RED indicator lamps which are incandescent with RED LED ones I had purchased from the RV Repair shop in Wildwood Florida which Lazy Days now owns. I mainly bought those for all of the water pump indicators as those are on ALL the time 24/7 as we always leave the water pump on even though we are hooked to shore water because sometimes the shore water pressure will drop which then the onboard pump will kick on to supplement the pressure.

tmw188 Posted June 8, 2021 Author Share Posted June 8, 2021 Well that’s where I thought it might be without having looked for it yet. He says in the front left bay? Link to comment Share on other sites More sharing options...

Mine is in the rear engine compartment Electric panel passenger side. I removed mine 15 years ago. Good riddance. That's where his should be ?

tmw188 Posted June 8, 2021 Author Share Posted June 8, 2021 So you guys are not wanting a House Disconnect switch at all? I like them especially on this knew coach, the wife will inevitably leave something on! Why do they fail so often? Link to comment Share on other sites More sharing options...
John Haggard Posted June 8, 2021 Share Posted June 8, 2021 Any jump wire will work Turn your switch on at front door Turn your radio up maybe half way Leave your coach door open Go to engine compartment and jump the domestic solenoid, your radio should blare away.. Or try another back next to it. Replacement is your choise. It's your preference. NAPA has them in stock. Cary extras 😉🤗 Link to comment Share on other sites More sharing options...

If it failed before I have a manual but no Electric schematic and none in the download section, I have asked REV but no response yet. I can only wish it would fail because I would never fix it. That button has been pressed dozens of time accidentally. Link to comment Share on other sites More sharing options...
Wrayj1 Posted June 9, 2021 Share Posted June 9, 2021 On my '07 Holiday Rambler Endeavor it's in the outside compartment under the driver's side window. Mine went out in February, I ordered from Amazon and replaced it, but also bought a 12-14 inch battery cable to bypass it while waiting for delivery of new solenoid. I agree with others, if it fails again permanently bypass it. Link to comment Share on other sites More sharing options...
Chuck B 2004 Windsor Posted June 9, 2021 Share Posted June 9, 2021 Just put all the red cables on one side of the battery cut off relay. Disconnect the small wires and tape them individually and store them. Chuck B 2004 Windsor Link to comment Share on other sites More sharing options...
Tom Cherry Posted June 9, 2021 Share Posted June 9, 2021 Here is the preferred bypass....assuming you do not have ENOUGH slack to move one cable to the other side's stud and bond them together. If you use a longer one, you will run the risk of a small voltage drop. I actually pulled mine out and ran the "house" side straight off the Blue Seas House Cutoff Switch....way less clutter and if I ever had to replace a component or the Blue Seas switch, I would have had to removed the idiotic relay (Solenoid) anyway...

tmw188 Posted June 9, 2021 Author Share Posted June 9, 2021 Ok thanks guys. I’m home today down with back actually been pushing it too much the last week. So it may have been bypassed already and that’s why it doesn’t work? Link to comment Share on other sites More sharing options...

Dr4Film Posted June 10, 2021 Share Posted June 10, 2021 Todd, you are looking at the wrong relay that I had stated in my very first post in this thread. That relay you have photos of above is the Battery Isolator Relay which combines the two separate battery banks, chassis and house, together in case your chassis battery gets too low to start the diesel engine. The White-Rogers Relay just below that one is the Battery Cut-Off Relay which is attached to the useless "salesman switch" at the entry door. Look at my photos that I had posted previously to see the difference between the two and where they are located. 1 Link to comment Share on other sites More sharing options...
