I have a 2008 Sunsport 22V with the Indmar Assault 325. Been a great boat. I just put in two new batteries and was ready to fire it up for the season and ran into a challenge. All accessories work but there is no power to the instrument cluster when I turn the key and it wont turn over. It is basically totally dead, no clicks like you normally hear when you turn the key and no dash life. I have checked the voltage regulator and switched to multiple positions. I have switched and checked the new batteries. I have double checked all my wire connections to the batteries. I checked the ignition fuse under the dashboard and switched it with another 10amp accessory that is working. I have checked the connection at the starter. I have found 3 20 amp fuses in a wire harness at the back of the engine and they all look good. I've looked for any lose/disconnected wires. I'm sure this is something simple, but I am missing it. If anyone has run across something like this before I would greatly appreciate some advice. Thank you very much. Dean Jackson
