Re: Yanmar tach reads low rpm

I think that schematic is for a Teleflex tachometer, not necessarily the stock Yanmar one. Look at who produced it.

My Yanmar tach has a fixed setting for number of teeth. It is written on the face of the tach (something like P=127).

Thanks for copying the image over!
