Hi All, anyone know where to find a wiring diagram on a yamaha 704 control? Got buzzer going off,and all lights on and flashing except temp.Thanks james
 
i'm confused. you say the buzzer and lights on a 704 control box. the control box houses the buzzer but the lights are on the tach gauge, right? there is nothing really to know inside of the control box but if the tach is set to 4-stroke and you are running a 2-stroke false readings will accur or vise versa. was the tach and rigging used in a different application? let me know i will tell you how to change the dip switches to proper stroke motor
