New project......replacing TV in a 382.

The TV/DVD unit I found uses a 12 volts. It came with a lighter plug and a wall transformer. I just cannibalized the power cord from the lighter plug.
If you do go with a 110vac unit and need to use an inverter, you will probably need at least a "modified sine wave" type, if not a "true sine wave" unit. Cheap square wave inverters are likely to wreack havoc on anything electronic. I would think that a couple hundred watts would be enough. Check you TV specs and go at least twice what it says the current draw is. (Watts = volts x amps.)
Found pictures of my busted TV and the finished TV/DVD conversion. (And YES - I did clean up the wiring behind the TV!!!

Just curious, how long does your battery last for w/ the tv on??
I am going to run a 1500 watt inverter, have a 160amp alternator and an isolator to constantly charge the 3rd battery. Have the battery, and isolator mounted, have to get my a$$ together and buy a tv.
Your set up looks very clean, nice job.

Thanks for the compliment - It took a LOT of hard work, including bandsaws, milling machines, and more. That was just for the acrylic ("plexiglas") part. You don't want to know how much work the polished stainless housing was.... 
I have two Group 31 combination deep cycle/starting batteries for the starboard engine and house power. TV's draw so little current, I would expect it to last about 3 days before drawing those babies down! Since I can combine the two banks of batteries if need be, I don't worry too much about draining the house bank down. That's also why I use combination deep cycle/starting batteries. If you drain a starting battery really low, you'll cause permanent damage.
Bear in mind that there is also a slight voltage drop through the diodes in an isolator, so your batteries will always be a couple of tenths of a volt lower. You can use a combiner instead - They usually cost more, though.
