@Susquatch my update to my digital tach dilemma. So I connect the 12 volt digital tach set up to my vehicle battery, although the sensor light came on there was no sign of life from the digital display even with passing the magnet by the sensor. Was working before I removed the kit from my lathe. Now I'm completely mystified with that. Shall pass the challenge to our son in Regina tomorrow. Meanwhile a new 110/120v - 12v converter is on it's way from amazon, should be delivered Monday.

Lost somewhere between + and - although always grounded. LOL
