Why reinvent the wheel? Look what I found! I have done this in class while repairing tvs... a looong time ago. I haven't taken a computer monitor apart for a while. I forget... do they have a suction cup on the glass also?

I don't know why the author used a probe. I would just get a double sided alligator clip cord.
Clip one end to the metal parts inside the monitor... the chassis or braided ribbon cable. I don't agree with clipping it on the truck... there will be no way to close the circuit clipping it on the truck. You have to close the circuit by grounding it to something inside the monitor.
Be careful with these. I don't know if the shock will kill you, but falling into your rebar pile, tools or concrete will.
5 years of electronics training and this is all I remember...
That... and hooking up a capacitor backwards will make it go off like a firecracker. The class clown was in my electronics class wanted to be funny. He grabbed a Cap from the parts bin, hooked it up backwards to a bench power supply and cranked it up. BANG, smoke, little pieces of capacitor everywhere. Instructor knew who did it, it was the only one of us white as a ghost and shaking a little bit.
