I am trying for months to install a Tachometer on a Yanmar 2GM20F.
The alternator is an Hitachi LR155-20 55A.
The gauge do a self test when turned on so it should be working.
When conecting directly from the alternator "W" wire to the gauge it shows full RPM.
Tried to switch the conections on the sensor without sucess.
The sensor is screwed until the end (can't go deeper).
I instaled a "W" wire on my alternator according to this instructions
This is the sensor
This is the gauge
Any help would be VERY welcome!
