Today I was working on my lathe at home, and as I reached over to grab the air gun off the mill table, I felt a little tickle.
I got out the multi-meter and discovered I had 17 volts AC coming from the lathe when running.
I then ran a ground wire from the junction box on the back of the lathe to the ground wire in the wall box.
The stray voltage is gone but what is the cause and how would you try to track it down?
The lathe is a 3HP Harrison M300, running off 220v into a teco N3 VFD.
It has been set up like this for years with no issues.
