    Mystery Box in Engine Room

    I have a 14 X 18 closed electrical box wall mounted next to my battery charger in my ER on my other boat (56 Ocean). It has three switches on the outside labeled hi/low, on/off and hi/low respectively. I opened the box and found two transformers and a few relays. It has one 110v lead going in and two 12v leads coming out. Any idea what this box is for?

    Photo is not easy to come by, at least in the near term. The on/off switch has been on since I bought the boat and there is definitely AC coming in and DC going out. Could it be some sort of battery conditioner? Really weird to have those hi/low togles(2) on the side.

    Take a look at your full compliment of wiring schematics that Ocean provides to all Owners. Oh wait, its Hatteras that does that. Nevermind.

    Any other ideas? The hi/low switches are what throws me.

    Could it be for lights?

    A 50 ocean in worked on had 110 volt to 24 volt transformers.

    Sounds like lighting. Do you have 24v spare bulbs anywhere?

    Just follow the wires.

    You could use a Fox & Hound to trace the wiring...
