2009 ski nautique 196 complete loss of power

Currently stumped on a diagnosis for this issue. I put the boat in 2 days ago after de-winterizing. Ran the boat 5 or 6 times out of the water without any issues. Put the boat in ran it up and down the lake still no issues. After my first set, I get in and go to turn the boat back on and it has 0 power to anything. Put a voltmeter to the battery it still had plenty of juice in it. I am thinking it may be a cable off of the battery but I am not 100% sure. I also checked all fuses and fuse boxes. Anything suggestions help!

Have you checked your battery switch? Hasn't happened to me (yet) but it did happen to a friend's boat. That would still leave juice at the battery but nothing past the switch...

Mine did the same thing this weekend. I had 12V on the wire coming into the switch and 3.5V on the wire coming out of the switch. I found a replacement switch with a slightly better rating at the nearest ace hardware and swapped it out. The hardest part was finding a switch that looked decent yet had the same function as the old switch (SPDT). Since the new switch had screw connectors and the old switch was 1/4" blade connectors, I created (3) 2" pigtails to bridge the gap then installed shrink tubing over each of the connections, including the screw terminals. Problem solved.

I'm not sure if your boat has the same setup, but just follow the voltage from the battery until you find where it quits being 12V.

This assumes you have had no grounds come loose. I'm not sure how to trace that since I've never had to do it.
