My underwater lights are not working and I think it is the switch as they wouldnt turn off and had to keep pressing switch till they did, now wont turn back on.
It is on Acc1 and want to move to another switch on the dash panel.
Does anyone know HOW as I have spent ages searching the web and forums?
Should be just a simple task I assume.
It is for the underwater lights and assume the fuse is under steering of the helm, which none of the breakers have popped either.
 
Look in your wiring diagram (in your manual - you can probably find it on Sea Ray's website if you don't have your original one)... find out whether the forward or aft EIM controls the lights (the aft EIM is usually in the bilge). Between the dash switch panel and EIM is all digital, low voltage. But on the downstream side of the EIM, it's back to normal 12V. At the EIM is where you would make the switch. Make sure not to use a breaker at the EIM that is larger than the original.

Thanks for this.
I am guessing that the soft switch on dash ma have failed (hopefully thats all it is) and want to move it to a different switch. Hve a guy coming on my boat today who does electrical so hopefully can be quik and simple.

Thanks again for prompt reply on this. I might get some photos and post to help others
I am selling the boat so buyer wants fixed! He said about $7000, I said, not discounting so he moved on and have another buyer who will pay more.
