Stray Voltage in the Milking Parlour

[Dragon]

So if everything is properly earthed I would have thought an earth leakage breaker should trip the power off.if it detects voltage on the earth ?
Not an expert though

That what is supposed to happen. Receiving 1.5 volts through the stall work when heater switched on. The heater works fine. Its all well earthed.

Why not put a new element in the water heater ASAP?

I may do that, first though was to eliminate the cause whilst milking. It could be the time clock, contactor.

Fair enough, although I doubt the contractor or clock would be an issue. Very much likely to be the element gone ganky.

I had all the cows reverse out of both sides of parlour one morning
I was quite concerned, was afraid to touch anything myself at first
Same happened at same time next morning
Next morning no problems but had no hot water as element in water heater fried
Replaced element, no further problems
