Hello, is my slip hot or what?
Measuring current via galley sink through-hull, while grounded to stove.

What sort of stove?

Is it a gas stove with a power source that produces a spark to light the burner at the press of a button (or by depressing a knob)?

If so, what is that power supply: a dry cell? a link to ship's power? a piezo-electric crystal?

[skilld1]

Piezoelectric.

I can't tell what units your meter is set...is that volts or millivolts?

By coincidence the other day I was checking some readings between our bronze through hulls and our battery negative. I was getting readings of around 60 to 100mV. The salt water is an electrolyte and the various metals are like battery electrodes but to have 8 volts seems excessive and maybe could cause leaching of the metals into the water. I was pretty ok with the 60mV readings.
