Pegasus - thanks for the reply. You are correct, that one red wire does go to the alternator. However, the one that I could not account for went to a non-fused distribution block for things like my VHF, stereo, etc, that were not wired to the fused / toggle switched DC panel. These devices all have in-line fuses. I guess they wanted these devices to come on, as soon as the battery switch was turned on, without having to flip on certain panel toggle switches.
More likely the DC panel ran out of breakers before they ran out of boat bucks
