So I go to check my bildge pump,blower, lights and etc. None of them will power on when I pull their switch. Thinking dead batt or fuse but knowing I have 2 brand new batts this shouldn't be the problem. I checked the fuses none where blown. I turn the key the engine will fire and no sign of dead batt. I pulled the switches on all accessories and still nothing? So I left home and went to get some food when I pulled back into my driveway I notice the running lights in front of the boat were on (I left the switch pulled out on accident) so I walked up to the boat and turned on blower bildge running lights and interiors light. All of them came on no problem . Last weekend when I was on the water I had the same issues but also I wasn't able to crank the engine everything was dead. After a 10 minute wait I tried to crank engine and all accessories everything worked. I'm puzzled as what would be causing this "black out" sorta deal.

There is an intermittent open circuit somewhere. Turn on the affected accessories and wiggle wires until you find the loose one(s) when the accessories power up. Check under dash wires and switches, and battery connection /engine compartment wires. Grab and shake them. You could speed up the troubleshooting with a voltmeter and check for +12v on the positive supply lines. If plus is there then you have a bad ground somewhere. Pull out fuses and clean corrosion off their contact points if present.
