Hi,first time I have been here and I need some help.We have a 2007 19" 4.3 190 hp Sea Ray with 50hrs. on it.Never had any trouble till the other day.I tried to start it and it was dead.No insterments,the dash was dead along with the ignition.No lights ,no horn,no gauges.The only thing that works is the trim pump,the battery is fully charged.I checked all the fuses on the engine and under dash plus all the wireing pluges.I can jump the starter with a screwdriver on the solenoid and it turns over so there is juice to the starter but thats it.Also checked the breaker,its ok.I did run across a thermal coupler back by the battery with a button on it ,pressed it but no help.Not sure what its for,something to do with heat?Boat ran fine the day before,all the gauges were in spec.Any help would be greatly appreciated! Thanks Mark
