Seems I was only getting 11 volts to my auxiliary fuse box that I installed. The fuse box home-runs to the deep cycle Optima battery and is used to run our Engel Refrigerator.
Looking at my original wiring, I realized it was a bit of a hack job, I had a couple of splices, that I am guessing I did due to the fact that I ran out of wire. 😉
I ended up running two new 10 gauge wires from the Optima battery to the auxiliary fuse box.
Which then run through the passenger side firewall
and end up powering the auxiliary fuse box
The end result is that the aux fuse box gets plenty of power which in turn runs our Engel Refrigerator perfectly
