Dec 31, 2013 / TN75A tach problems #1 T Telllico New member Joined Aug 1, 2013 Messages 1 Location Tellico Plains, TN Tractor MF165 Tach is intermittent. Works perfect at times. Sometimes it will show 1000 RPM at full throttle. Hold full throttle and tach will go to zero. Hour meter will keep working fine. Any ideas?
