The wiring for the main power systems is correct in my belief. The diagram not so much. Mike's pictures here are just a subset of the ones he took. You are right, the main wire from the battery is hard to see in the pics. If it were as Mike's diagram shows, there is no way to get power to the fuse panel (among other things). Just to be sure Montana hasn't changed the standard wiring, I went to my dealer and looked at 4-5 Montana wiring systems. They still run it the same with the battery going to the right hand CB ("C" in the diagram).

What is really weird and the genesis of the confusion, is Montana using a resetible 50 amp CB for the inverter. They must have been out of the Magnum fuses and grabbed what they had so they could go milk the cows. Quality Control at its finest.
