Federal law requires that the LP detector works all the time when any RV leaves the factory. You may have additional draws for radio memory, lighted USB ports, etc.
Adding a disconnect at the battery is the only way to totally turn off the battery(s). Factory uses positive lead, we install on the positive side, others will say the negative side. I don’t think it matters in the RV world.
Does everything 12V still work? If so the switch may have failed or it may be wired incorrectly.
