Hi Will,
Please don't post the same message in multiple threads; users on the forum usually look for "new posts" and contribute when they can.
Not sure if you were referring to a physical disconnect switch near the battery, or the "Use/Store" switch. In any case, there is usually a high amperage fuse or circuit breaker located near the battery. If it's a circuit breaker, there is often a yellow or white lever that drops to show the breaker needs to be reset, and you just push it back up into place to reset it.
If it's a fuse then a meter is helpful to show whether there is voltage on both sides of the fuse holder.
Not familiar with your RV model so I can't be specific.
