      Check the main fuse AND fuse holder by the battery. I had the same issue with my boat.

      The 40 amp fuse at the battery is fine, I think the master circuit breaker is broken, I took it out and when you shake it there are pieces loose on the inside

      Hopefully that fixes your issues. Like I said, I had the same symptoms with my boat. Turned out to be the fuse holder and the wiring had corrosion that wasn't visible. Looked like the wire had corroded inside the jacket.

      I replaced the circuit breaker and still no power to master switch, any ideas

      Did you test to see if you are getting voltage TO the panel?

      Read my response above. Check the integrity of all the connectors, fuse holder, and wiring near the battery.

      Do not replace any more parts, until you first take a VOM and check voltage at each point where there is a connector between the battery and the Breaker. You are going to find either a broken wire or a bad connections by that process.
