2005 Sundancer 340 DA. Recent storm at my marina resulted in loss of shore power to my boat for 5 days. When I found out about it I went to my boat and found everything shut down. I couldn't get any of the dashboard switches to work. I decided to run the boat to charge batteries. Starboard engine fired fine but Port side engine message said "engine not communicating" had to use emergency start on Port side engine. I went on a 1hr drive during which the entire Starboard side of the guages stopped working. I docked it and turned everyting off. The power is now restored to the dock and I am going back today to see what I can do. Any suggestions? Thanks
