tmw188 Posted June 10, 2021 Author Share Posted June 10, 2021 (edited) I wondered about that because of your second photo otherwise you wouldn’t have taken that photo, and the way it’s called out on the diagram it did say disconnect. I was looking for what looked like a solenoid the other really didn’t look like one that I would recognize. This is it here?

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. You sure did, sorry I had forgotten or got distracted with other posts I guess. 👍 Looking closer at that photo above it appears that there is a purple wire taped off to the side, that might be for the disconnect switch?

tmw188 Posted June 10, 2021 Author Share Posted June 10, 2021 (edited) Well Sheet! This is it I guess what the heck I’ll get over there this morning. Didn’t really recognize it. Mine does not look the same I don’t believe. This is Dr4film photo. Edited June 10, 2021 by tmw188 Link to comment Share on other sites More sharing options...
Dr4Film Posted June 10, 2021 Share Posted June 10, 2021 YES! As you can see I have bypassed it already and it has been that ways for 10 years or more. I can't recall when I did it but I wasn't going to throw more money at a POS solenoid relay that will fail again. 1 hour ago, tmw188 said: I wondered about that because of your second photo otherwise you wouldn’t have taken that photo, and the way it’s called out on the diagram it did say disconnect.

tmw188 Posted June 10, 2021 Author Share Posted June 10, 2021 (edited) PO? Previous Owner Yes! I assume so. That’s what you need to do to bypass the disconnect switch I assume. I don’t know though there is only 1 post. Edited June 10, 2021 by tmw188 Link to comment Share on other sites More sharing options...

Todd, someone has already removed the Battery Cut-Off Solenoid and installed a single post connection mounted in the same location to bypass the useless piece of junk. That single post has the two wires connected to it. End of problem. That's why your entry switch does not do anything as it has been disconnected. By the way, yes the purple wire I have taped off is the control wire for the failed solenoid relay. All it basically did was to complete a ground circuit to the solenoid.

tmw188 Posted June 10, 2021 Author Share Posted June 10, 2021 Yes!! That’s why it only has the one post, they just took it a step further. So what is it that it fails regularly? I really would like to have that switch operable because I’m so use to having one? Link to comment Share on other sites More sharing options...

tmw188 Posted June 11, 2021 Author Share Posted June 11, 2021 Thanks everyone I’ll see what I end up doing about that. It’s a big coach with a lot of 12V accessories, it’s easy to leave something on. It’s not on my short list yet. Link to comment Share on other sites More sharing options...

Dr4Film Posted June 11, 2021 Share Posted June 11, 2021 (edited) Todd, It was for me when the damn thing failed during the night sometime and it was raining cats&dogs outside. Had to get up and use the toilet. No lights, no refrigerator, no toilet, no Aqua-Hot heater, nothing, nada, zippo! It was bypassed the next day and haven't missed it for one nano-second. If you are only out for a spell, leaving a light on is no big deal especially if they are LED's. If they are not, change them out. If you want to turn the entire house off use the Domestic aka House Battery Disconnect switch in the RRB. Edited June 11, 2021 by Dr4Film Link to comment Share on other sites More sharing options...
jacwjames Posted June 11, 2021 Share Posted June 11, 2021 While I was getting my garage built I had the coach parked off to the side not accessible to electric, I was having to rely on the 325 watt solar to keep the batteries charged. I found that I could turn the disconnect off and I could maintain the batteries without using the house battery disconnect which shuts off power to the whole house. Prior to this I seldom used the house disconnect. I've been working on my coach quite a bit lately and was concerned about my battery mainainer so I've been testing it and the house & chassis batteries. Yesterday, after reading all these posts on the "Salesman" switch I inspected it and when I touched it it was hot, could not hold my hand on it. No idea of how many watts of power it took to create that much heat in the solenoid but imagine it is quite a bit. I'm going to do some amp readings just to get an idea but I am leaning toward just bypassing the solenoid to save energy drain unless there is a more efficient option of keeping one in place.

Dr4Film Posted June 11, 2021 Share Posted June 11, 2021 (edited) Jim, the reason for the heat is the solenoid is a continuous duty one so it's always on. That's why it fails. The only way to get around that problem is to install a latching solenoid. However, you would have to run an additional wire from a properly installed momentary switch as the latching solenoid requires a positive & negative wire to activate the solenoid and again to deactivate the solenoid. The latching solenoid only needs power to latch the contacts and unlatch the contacts. It's not pulling power all the time like what's in there now.

tmw188 Posted June 11, 2021 Author Share Posted June 11, 2021 Oh yeah I’m already changing out all the lights to LED’s I did that on the other mh and installed a 100w panel to maintain the batteries which does a great job, next came the refrigerator. So kinda doing the same thing here except for the frig, other than they didn’t complete the install properly. Learning all the new systems.

Well I won't be doing that then, not worth the effort. Link to comment Share on other sites More sharing options...
