Hi All,
Have a pair of 1990 yamaha 150's. Both engine tachs are reading "0" after start-up and do not change with RPM increase. Started out with the port motor then a few days later the starboard. All other functions on port multimeter are normal, starboard meter has all 3 warning lights flashing with a steady alarm horn. This I think is a seperate issue (faulty oil sensor). Connections, grounds etc. have been checked, don't know where to go from here.....
