Thanx to the suggestions, I easily found the switch box. The box no longer has any switch handles, and only a couple of shafts left.
So i had to go inside the box to check things.
NOTE: I am an electrical engineer and used to being around lethal voltages. Turning off the power to the switchbox would be the recommended procedure, but the only way I now how to do that is to turn off the breakers to the boat. I am not sure the visitors would be amused.
When the switches are on, the voltages at the output of all 8 switches are good (120Vac for the Lionfish). I can see lights turn off/on in the FTR when turn the switches except one. The switch on right side, one down from the top, labeled "S&RS Port", doesn't seem to effect anything. Not all the light sockets have bulbs in them, so not seeing a light go off may just mean it is missing from the socket.
Anyone know what switch turns the escape hatch light on/off?
