If it is set up like my Sea Nymph and other boats I have seen, there is a block under the dash or near the dash that all the toggle switches run to. This happened to me during a tournament a couple years ago. Gauges worked, toggles didn't. To save time, ran a temp wire from the switches back to the battery, that isolated the issue with the block under the dash. Again, sounds like something simple that might be being overlooked in the frustration/heat of the moment.
