I have a 1988 50 hp force.
I noticed towards the end of last year the tack would jump and not keep a stable reading. Had the boat out tonight and when you Turn the key on the tack will go to zero. Once the motor starts it will go straight down to the 6:00 Position and not read. I have checked the wires in the back of the tach and they all seem ok. Did a little research and read something about a rectifier on the motor. Anyone have any thoughts or ideas? How can I rule out the rectifier? What checks would you suggest. Thanks. James
