Yanmar rev counter

Does anyone have any info on the resistance of a rev counter flywheel sensor on a Yanmar 4JH series engine?

My tacho stopped working and I read in a manual that the sensor's internal resisteance should check in at 1.6 kilo-ohms. Mine measures 1.2.

I just wondered how sensitive these things are. I suspect my tacho is toast but want to cover all the bases before spending unnecessary bucks on a new tacho.
