So, sure enough, no 24 volts! So I'll have to hunt down why that went
flaky. It comes from the rack of the original machine. Very well
built, but it is old.
So, (and I feel stupid), I had just mounted up this coolant head so we
could keep the chips cleared.

I had bumped the touch off connector box, which should have been mounted
to the machine.

The white, 24v, wire was touching the machine, voila!
I'm sure glad I posted here, thanks to you I didn't have to buy new
boards and still have the same problem.
Best, Dan.
