I don't know if this applies to what you encountered and what may have caused confusion, but I am working with an LTV Free Spirit Owner who ran into a different setup with his Isolator Solenoid and so once I cross walked his wiring he could move on with his Renogy DC-DC charger installation. The IRD is a switch, that doesn't signal the Isolator Solenoid to close until it's sure the chassis side is taken care of by the alternator before it allows the house to use it for battery charging. The two vertical terminals are for ground and a switch they can be wired be either terminal as long as the ground and switch wires are on opposite vertical terminals. You can see mine is wired just the opposite, Ird switch wire on the top terminal and ground wires on the bottom terminal, and still functions the same. Leisure always uses white wires for their ground/negative wires so that cluster of #10 white wires are simply ground wires that they stacked on that Isolator Solenoid terminal. Leisure is using the terminal on a broader basis as a ground bus terminal for the stuff wired under the seat (i.e. Awning controls).
