Well, I've been working LONG LONG hours and I must simply be very tired. My main starting battery in my dual battery system needed replacing. Long story short I ended up reversing the polarity on the battery! Bad news is that everything is dead. Hooking just the main battery back up (correctly), I can't get interior lights to come on, obviously not started and she's dead. I've checked all links, fuses, relays, etc. So what did I fry? What can I check? What are my next steps?
