Re: Troubleshooting Dead unit

I wouldn't be too embarrassed.? That sort of thing happens to most everybody.? And if not, it is because they never DO anything.? And even though a simple fix, it helped to go through some steps and then you got there.
I was once testing a very high impedance op amp amplifier circuit I was designing and was getting all sort of noise.? I checked all sorts of things.? Checked that the oscilloscope was isolated.? Everything.? Was at it a couple of hours.? Then I realized I had not turned on the power supply to the board.? With no power, my circuit was basically just being an antenna.
The GOOD news is that there was no electronic issue with your lathe - this time.? But with a schematic now, you will be better prepared if some issue does arise.

I want to thank everyone for their suggestions, which seemed particularly good.? I was able to print out the schematic, thanks.

I started trying to measure voltage on the control board.? Nothing.? ?I could not even see voltage on the AC line......? That is when I checked, and found that the extension cord that the lathe was plugged into had become unplugged somehow.? I had been using that extension cord to power a bandsaw earlier in the day, so I assumed that it was still plugged in.? An embarrassingly simple solution.? ?I know perfectly well that when something is not working, I should first check power, AC or battery.

Thanks to all,
