I have a 2002 Tiara 3800 with 517 hours. Yesterday, when I got to the boat one of the first things I do when I get on the boat is open the window vent. Didn't open. Blower didn't turn on. Windshield wipers didn't turn on. Hmmm. Then I turned on the key to the port engine....nothing. Once I pushed in the battery parallel the port engine started. However, as soon as I took my thumb off the battery parallel the engine stopped. I did notice that all the items I mentioned earlier worked with the engine on (while my thumb was on the battery parallel). I even turned on both engines (with thumb on battery parallel) and as soon as I took my thumb off the battery parallel the engines turned off. I checked all the engine batteries and all registered 13.59 volts, but this was with the battery charger on. As I did all of this I was on shore power. Any advice?
