In theory you can figure out a way to rig up a multimeter to test the voltage coming off the power supply while the thing is running a job and attempting to lase. I’m not sure what voltage the tube runs at though, nor how dangerous that voltage would be.
You might try the open glow forums, there are still a few users there that are active they are all fairly technically minded.

And, nope, you don’t want to do that. (This is one of those “if you have to ask, then don’t do it” situations.) The high-voltage side is running at 25,000 DC volts. Although it is small amperage (20ma), it’s easily shorted and then, bang!

I just had the same problem. Watched a couple video from Wireglass Technologies on how to remove and repair the red wire.
Glowforge looked at my log and advised me that I would have to return and wait.
purchase a refurbished one 1500.00 or contact wireglass and get a price from them for repair.
In their video they advised that in 85% of the time the wire that runs under the laser arm is shorted out.
I’m going to pull the wire and check it.

Got a url for that video?

Looks like it’s this one (search for “wiregrass,” not “wireglass”):

I completed my wire repair per the video. The laser started engraving for about a minute and shorted out again right where the power wire goes in the power supply.
Had to order a replacement 1600.00 and change with shipping.
