No Power Issue - Need Help Diagnosing

My 2013 276 Cuddy is having an issue. I hooked up the three batteries like normal and I'm getting zero power sent anywhere, except for the bilge pump. That turns on and lights the dash button like normal. 

I've checked every fuse and breaker I could find and no luck. 

Any ideas where to start? Am I right in thinking not likely an ignition switch issue, because I dont need the key in to work the lights or some other accessories, which have no power. 

Would a bad battery switch cause what I'm experiencing? If it wasn't sending power when I change positions it could always act like "OFF" right?

    Also, I am able to life the hatch up & down as designed by connecting a battery directly to the "hatch override" terminals. So it seems like power works for the two items designed to be used with direct power.

    I've had two battery switches fail on my 2011 boat.  The backside plastic bits crack, and then there's no pressure holding the connectors together.  Take that panel off and look for obvious physical damage on the back of the switch.  If there's no obvious damage, check continuity with a multimeter.

    It's not the ignition switch and the bilge pump(s) by-pass the main battery switch The breakers with yellow tags, are they not supposed to be closed so they are not visible.

    Yeah, I was cycling those yellow breakers when I took that pic, none had tripped themselves. 

    I took the rear plastic cover off behind the battery switch and everything looked snug, but its an annoying spot to see well. I'll be going back tomorrow to take another stab at it. I'll take my multimeter too. 

    I assume if I dont see continuity from one terminal to the other with the switch "ON", that means the switch is bad, correct?

    Yes, if you do not see continuity or voltage then it is the switch.  Definitely the first place to start. My son just changed his out on his boat this past weekend.

    Did you reset the main breaker on top of the motor?
