You need a new disconnect switch and a voltmeter to determine what large power drain is killing the battery. You could also have a bad battery that needs to be replaced for free.
On our GS motorhome, the house battery disconnect switch totally isolates the battery from the coach. This is a great feature in storage because it stops all of the "phantom-drain" from clocks, safety detectors, relays, and electronics.
If your disconnect switch is working correctly, you should not have any drain or any voltage at all on the house side of the switch. The clicking sound is a relay or solenoid when you touch ground. Our generator is hooked to the house battery, and when the disconnect switch is off, nothing happens with the generator. With the disconnect switch on, the generator has to have the ignition switch off before it will crank, even though it is NOT using the engine battery for cranking. That is the relay or solenoid clicking noise on ours. No idea why somebody at the factory thought you should NOT be able to start the gen when the engine ignition switch is on. The slideout is wired the same way but I can understand that wiring so you do not accidently hit the slideout switch when going down the highway.
