okay, so, we've been having a ground fault issue on the server rack and i invented and built a simple testing tool and it WORKS iT WoRkS it wORKS! and as a result now I know this:

ups ELDA is handing the ground pin 54-57vAC at 17mA and 7-20vDC (variable) at variable up to 19mA.

I can confidently say That's Bad and I've pulled it and stuck server elda on ups LODESTON with server lodestone while I try to figure out if there's any way an internal lead-acid battery fault could cause this.

I don't think so, but am I wrong? Could it?

eta: ex-MSFT friend came up with a good test and it's definitely not the battery. Ding!

Lisa says she can't think of any way the battery could be at fault here. "I'd be suspicious of the filter capacitors," she told me.

Good luck hunting down the fault!

Can't help with the electric problem, but I am amused (though not surprised) at your server names.

Is this why the Murk is down?
