the round thing on top is a fume detector ( I have the same one on the monte carlo) Mine turns on the blowers if fumes are detected and sounds an alarm if more fumes are detected.
its a heart invertor/charger control panel. Heart invertors were very popular a few years ago. They got bought out by some one else. I personally don't like invertors and have not had good luck with them on boats. I've known some people that think the heart is the best one out there. Look around in the bilge and see if you have something that looks like a stereo amp. That's what that panel is controlling
it allows you to run ac accessories off of 12 volt dc batteries. I've seen a few boats that have them and they work ok, I've seen more that had invertors adn they were always trouble. There's a bunch of information out there on the heart, it seems to have devout followers.
Sounds like your living the dream there. Dare I say, some of us have to work.. Sorry about the damage to your ribs and liver, hope recovery is fast and relatively painless. Love the Bar too.. Congratulations.
