Here’s what the PT is doing unhooked.
Checking continuity, between yellow wires, .6 ohm, between red, 331 ohm, green to green .3, so there’s no major shorts in there, but:
measuring ac voltage with a true rms dmm
Across green wires 6.79 vac, and across yellow 5.3. Is that right? If those are half what they are supposed to be, could I run one leg to one side of the tube and ground the other? Think I read that somewhere.
Please advise on what you think about the health of the pt.
