Fuse 3 is removed and left out but another fuse is added to take it's
job. That is why I said to put a fuse on the wire you run from the aux
bat to the fuse panel. Get an inline fuse holder and put it in the wire
near the end at the aux battery. 15 amp should do.

A fuse is nothing more than a special piece of wire that melts when too
much current flows through it. The wire (fuse) connects the power source
(battery) to the power consumers so electricity flows through it
whenever the consumers are turned on. When you remove the fuse, power no
longer flows through to the consumer. Fuse 3 has 2 legs with the tiny
special wire connecting them. Both legs plug into slots in the fuse
panel. The top slot connects to the main battery. The bottom slot
connects to wires that go from there to the radio, interior lights, cig
lighter socket. With fuse 3 pulled, the slots are empty and the special
wire is not there to connect the main battery to the bottom slot.  When
you plug a wire from the aux bat into the bottom slot the radio, lights,
and cig socket will get their power from the aux bat.
