Stray AC voltage in tank

[Delphinus]

In my case it's 1 VAC. It's barely a bump on my smallest AC sensitivity which is 0-10 VAC, higher ranges it doesn't hardly show up at all. But it's there...

(BTW, I can't measure AC amps. I can only measure DC V, DC amps, and AC V. DC V is zero as is DC amps.)

My fans are grounded as is the metal conduit I use to mount the sockets to my canopy, but that's not to say there is not a break in the wires. I've been out of town so I haven't been able to chase this down yet. Now that I'm back I think I'll double-check my grounding wires...
