I have a 2004 340 Sundancer. The starboard switchpad does not operate, but has 2 switch lights on. The local dealer wants to replace the switchpad and the fuse-type box under the dash. Naturally this will cost over a grand. Has anyone solved this problem by replacing one or the other of these items? They do not know what part actually is the problem, but follow Searay's recommendations. There is also a MUX processor that all the power cords plug into. Could that be the problem?
 
I had to replace both of mine when I had a nearby lightning strike. I guess the "fuse-type" box you are talking about is the Electronic Interface Module. You could see the damage on mine. some things worked others did not.

Is the dealer able to get both? they were in short supply when I had my problem 2 years ago.

see the fried circuit board on the top center of the module.

Not trying to be sarcastic, I really don't understand...
What is the purpose of replacing cheap, ultra-reliable, uncomplicated toggle switches with circuit boards and relays??

Someone, please enlighten me!
 
I would prefer toggle switches. How much for Vector to remake these panels a little more simply.

Service parts are the OEM's best friend! I like rocker switches too....but the way the helms are layed out on the late model Dancers to accomodate electronics the switch pads with all of the circuit boards seemed to be the solution to conserve space. I don't know if the labor savings to plug it all in offsets the cost to make it though.....I think the rocker switchs are making a come back on the new stuff.
 
Had the same issue rwith the switch pad lighting switches up by them selves. I tried the EIM (Relay Box) first but since that did not work I had to order a switch pad. These are hard to come by but there is no way to test either of these parts with out swapping them with parts that you know work.

Must be fewer wires and fewer connections to loosen over time. Nice idea, but not without its own problems.

Glad to have toggle switches myself!
