Optimax motors are extremely touchy about the cranking battery and their connections. I have seen more problems with the ignition switch than with kill switch on a Mercury. Evinrudes are a different story. If you don`t hear the warning test beeps when you turn the key on, you don`t have 12v to the PCM.
The world will not be destroyed by those who do evil, but by those who watch them without doing anything. Remember what He has done and remember that He is not done yet!-- GOD IS GOOD
