I tried arching the coil wire to ground while cranking but no spark. I tried using a volt meter measuring DC voltage at the coil wire while starting. I saw 12V with KEY on then it dropped to 11.4 while cranking. I'm not sure if the coil is bad or the computer is not allowing fire due to a bad sensor some where. Does any one know what the red push button is on the side of the mounting plate that has all the EMISSIONS control garbage on it? I see and feel a red push button down there. I'll look to see if it is in the owners manual. I need to find a better way to trouble shoot the coil I guess. Its almost as if the kill switch is activated but its not.
I don't remember where I read it(somewhere on this forum) that the red button is a reset for the engine. Kind of like a separate breaker for just the engine electronics as opposed to the breaker for the whole boat. Could be wrong but pretty sure if it's out then something's wrong as it should be pushed in.
