Ok, If you have a disconnect on the negative Battery post. and it was Disconnected.. Then I have no clue why the Aux Start got the coach started other than luck.. Sometimes a battery can "Wake up" on the first try though in the summer that's rare (more a winter thing).

Why it won't work if you have a Disconnect on the House batteries.. Because they are disconnected.
