Alright, my apologies if this is a dumb question. Changed all my belts and impeller today, and put reflective tape on the three wheels of my Yanmar 3GM30F, for use with a non-contact, optical tachometer. Which wheel should I be measuring for the most accurate RPMs? I only ask because each wheel is giving me a different read out.
The alternator wheel is registering much higher than the other two. The lowest wheel seems to be giving me the closest readout to what’s on the analog cockpit tach, so I’m guessing that’s the one. Just wanted to check with the more seasoned crowd.
Also my apologies if I’m using the wrong terminology for the “wheels.”
