I have had some issues with my push-button disconnect switch not always working, and my emergency battery switch on the dash has never worked since I bought my coach. I have chased the issue with the emergency start switch and have basically given up on it. Today I had a thought that will resolve both of these issues but I want to run it by the geniuses on here. Perko makes a disconnect / isolator switch that has options for one battery, all off or both batteries connected. I'm thinking I'll place the Perko switch near the house batteries, run a 4ga wire to the chassis battery and abandon the factory stuff for both the use/store button and the emergency start button on the dash. I'll set the switch to off for storage and if I need emergency connecting between both batteries I'll just put the switch to the "Both" setting.

I will fuse the cable between the chassis and house batteries on both ends to protect against any shorts. Can any of you see anything wrong with this setup?

Don't give up on your use/store sw. Its made by Intellitec and the switch is quite reliable. What isn't reliable is the very small trigger wires that attach to the solenoid. Make the two trigger wires so that they are a good connection, tighten the big nuts on the two big wires and you should be all set. You can actually take apart the solenoid and clean the inside-its just a big flat washer that does get oxidized. Just clean it, check the trigger wires, and you should be good to go.

This should help trouble shoot, or wire in a new stow/store relay....as for the emergency relay, it is just a simple 3 pole relay, small center terminal gets 12v and it locks, remove 12v and it unlocks

I want a disconnect switch for my chassis battery but the switch is pricey.

Put one of these into the Negative cable between the chassis battery and ground connection. Not very expensive.

If you have an inverter , the switch should be rated for at least 200 amps. I would run heavier wire to the chassis battery , close to the size of the battery cables. Otherwise should work.

FWIW I prefer the cheap disconnects. Everything is out in the open so a failing contact is obvious. Not so with the enclosed switches that cost more. HTH, YMMV
