Re: Yanmar tach reads low rpm
I recently put a Faria tach in for my Yanmar 44; it reads fine to about 2400 RPM, then goes in reverse (showing lower) RPM as I increase throttle.
No calibration adjustment, just number of teeth (correctly set for 127).
Unlike the diagram I have a 'stbd sync' and a 'port sig' connection, both of which are connected.
Drives me nuts.
Lessons learned are opportunities earned.
