I have a '01 40HP Tracker (Mercury) that has a constant blaring warning horn when the iginition switch is on. This started while out on the water and everything I checked seems to be working as suppose to. Even after several days on the trailer in the driveway, if I turn on the switch the horn start blaring. Mine is apparently sonewhere around the ignition switch, judging where the noise is coming from. Do I have a bad horn module or could it be more serious?
