Hi Bobby,
The BatShare has to go before the regulators, the regulators cannot go before the BatShare if this is what you are saying. If you want to run two batteries into two switches into a BatShare and then the output of the BatShare into two regulators and then into your receiver this will work but you will be getting work out of one regulator only. You will loose the advantage of getting more current with less voltage drop between the regulator and the receiver because you
will be running the current from both batteries through the single regulator's 22ga wire and connector. Maybe I still do not understand your setup. Please help me understand.
