Battery Disconnect switch not disconnecting power

[Pacostaco]

I have a 2014 sun seeker 2860ds and the past trip I noticed that the battery disconnect switch did not disconnect the power when switched off and not connected to shore power. The lights stayed on as well as other appliances. I did notice that the speed of the fan lowered as well as the lights dimmed like it was getting half power. Not sure if anyone has had this problem before. It is an intermittant problem because sometimes it works fine. Is it possible the switch is going bad?

the switch should be a simple on / off switch. either 100% or 0%. no way it should only supply 50%. were you comparing the lights and fans to when you were connected to shore power vs when you are on the battery? if disconnected from shore power I would not expect the lights and fan to even come on with the switch disconnecting the battery. if you then connected the battery and there was a notable lowering of them it sounds like the battery is not fully charged. now, here is a possible explanation. if you are on shore power do you have the switch set so that the batteries are connected. they have to be in order to get recharged. if by chance you are on shore power and the batteries are not connected they will not get recharged. sorry for the nomenclature but I simply cannot remember if the batteries are connected or not when the switch says on or off.

I have the same problem. Do you have a p picture of your switch? I know of one other person with said n e switch and problems as me.

Thank you for replies. As I stated no shore power was hooked up. I have a very clear understanding of the switch and what it is supposed to do. I was hoping someone else was experiencing similar issues. I will take a picture of switch tomorrow. Thanks again

F____ it I took the picture now. It's a blue sea systems disconnect. Found them on the Internet. Probably going to go ahead and replace it.

Mine was misswired when I bought it. I had to rewire it.

I'm not sure how you wire a disconnect wrong but I guess anything is possible. When a disconnect is connected inline on a cable, all it does is break/connect that cable. There's not much in the way of parts to a disconnect and it is really easy to test.....very rarely do they go bad.

[Pacostaco]

I agree, but mine is definitely bad

When I installed my solar wiring I discovered that my battery disconnect switch had a second ring terminal on the battery-side lug which still provided power to certain things inside the TT. A cleaning and a cable rerouting on the disconnect switch lugs has resulted in a true 100% disconnect. Also inspect the positive post on the battery to insure there are no other wires going to parts unknown other than the cable going to the disconnect switch.

Pulled it out and only 2 wires, black and red. Ready ordered 2 new disconnects. I always order 2 of everything I fix just in case it happens again. I ha e fixed so many things it's unbelievabe. If I had to take it to the dealer everytime I would never get to use it. I also am very anal about it and keep it immaculate amd still things break. This year alone replaced both front tires because of bad alignment and camber issue, my propane regulator fell apart for no apparent reason, and a water line going to outside shower behind the cabinet sprung a leak. Ughhh

If you have an inverter you will need to shut it off before the battery disconnect. Otherwise, everything will run.

Ok, I found the disconnect on the Internet and replaced it. Easy to replace, 2 wires, all fixed.
