Or -- some meters when set to DC and fed AC will measure the RMS
[kinda DC-equivalent value] voltage of the AC...
100+V AC * .707 = 70+V DC.
The equation for figuring RMS voltage on sine-wave AC is:
1/sqrt(2)
(I've seen up to 110V AC myself [more on hand-cranked military
handsets], so that would get awfully close to the 80V the OP saw...)
Just a thought,

Still burns and leaves the God-awefullest metal
taste in your mouth
when
you get hit with a ring surge, You sure its
AC? Doesn't make
sense,
but voltage on my meter would jump up from
48-52vdc to around 78-80vdc
on the DVM
Yes, it's AC. That's why it hurts. DC would feel strange perhaps
but not
like AC. The reason you saw voltage at 80VDC is because your digital
meter samples slowly.
