Anybody know where to get a wiring diagram for the engine alarms used in the top guns? My starboard alarm works but port doesn't, its been like this since i bought the boat last year. I have switched the actual alarm side for side and everything works, so its not the alarm. When i turn my keys on only one side lights up and beeps...and ideas on where to start?

your alarm system works by the sensor sending a ground signal to the alarm.check your grounds
