True Ed. And they also isolate both banks on startup so that if your house batteries are way down, they will not draw down the chassis battery so that you cannot start your RV. Only when the alternator is putting out full power does the BIRD close the Trombetta to charge the house batteries. While it adds complexity, it also simplifies your daily operation. And if the system does not work the two posts of the Trombetta are 2 inches apart with cables leading to both battery banks. A 6 inch jumper cable will physically connect both batteries. Or, in a pinch, if you do not have a jumper cable, you could just disconnect the wire from one Trombetta post and put both wires on the same post or join them with a bolt bypassing the Trombetta.
