The angry wrathful technology gods at work (Click pic for a better view)
This is a case of the angry gods at work. This box is connected to sealed rubber covered switch pads on the dash, and is programmed to turn on chartplotters, stereos, pumps, and all of the other things on the boat. The boat is four years old now, and the box has failed, taking the operation of 16 pieces of equipment with it.
The box was made by Carling, who sold, or transfered it to another company. They promptly redesigned it, and discontinued production of the original box. There are no spare parts, no programmers for it, no wiring diagrams, no nothing period. The only option here is to remove the digital pads from the console, cover the holes with a overlay panel, and install 16 switches. Actually there is another box that controlled another 8 switches, so you might as well do all 24 switches at the same time. The boat builder feels bad about it, but can't do anything about it. It would have been cheaper to build the boat with 24 switches in the first place. Sometimes simple is best in a highly corrosive salt water environment.
