Hi,
Does anyone have a schematic for interfacing the ZR-700 with the Smiths tach? I have heard two possibilities: (1)put the tach pickup coil in series with the black lead to the coil negative and (2)put the tach pickup coil from the coil negative to ground. Can anyone weigh in on a successful application?
Thanks
Mike
