Disconnect Switch not working

I have a 04 Sea Breeze on a Ford chassis. Today, I went to the gas station to fill up while prices are still cheap. I got back and hit the battery disconnect switch like always and heard the click. After I shut the door the steps stayed out, which they normally don’t (that is another issue). So I opened the door back and hit the disconnect switch to reconnect the house batteries and nothing. No “thud” sound that is normally heard when hitting the switch.

Anyone have any ideas on where to start to try to solve this issue? Thanks!

Switch contacts are not making good connection. The switch on my Dolphin is doing the same thing. I just keep operating the switch until it works. I never turn off the main disconnect. Someday I replace the switch, not a high priority right now.

Just a possible heads up - the house battery disconnect relay is soldered on the main control board, located in the front passenger storage compartment next to the inverter in my 2006 SeaBreezeLX. NOT easy to replace. Also, the stairs are hot wired, so even if the battery switch (and my chassis battery disconnect) are off they should still work. At least they do on my rig.

The steps work off the chassis batteries, this is a safety feature. You said you are using the disconnect switch for the house batteries. Steps have there own switch. When you start the engine and the steps do not retract this would indicate a problem with the step not the switch.

So hopefully it will click back on? I rocked it maybe 10 times last night and nothing.

There is also a magnetic contact on your entry door and frame that you can troubleshoot using a magnet.

Do you have a voltmeter and an extra set of hands? Confirm if voltage is going to the relay coil when the switch is operated.
Or you can bring out the switch and jumper the contact to see if it is the offending part.

How is your system set up, only a Coach relay or Coach and Chassis relays? If the relay is not operating, what else does not work?

The magnetic contacts are for the steps. Your disconnect switch should have nothing to do with the steps. The system is designed to work with the house battery off, it gets it's power from the chassis battery.

I am not a guru when it comes to electricity by no means. I can plumb a house if I had to, but not wire one up. When I crank the engine or plug to power, the switch operates as it should. But when it it not running or not plugged up, the switch will not operate a few days later from the off position.

With that explanation, it sounds like your house batteries are dying.

Next time it don't switch on, check the house battery voltage.
