Stray Current?

[crewdawg1981]

So... If I put my hand in the sump... it hurts a lot.

But only if the finger with a cut on it goes in the water. Now... I realize that salt water and open cuts dont actually mix, but didnt know if open cuts actually made it easier to feel a stray current?

I hope I'm just taking crazy pills cuz I can unplug everything and STILL get the shock feeling. It sure hurts like I'm being shocked... I've had a maxijet go on me before. Take a shoe and sock off, stick hand in water = pain... but not that bad.

Try totally unplugging any power source from the wall and see what happens.

Edit: If the problem stops, then plug everything in one by one. My vote goes to the heater.

Sure you unplugged everything?

Bummer. Is this a cheap/easy to replace pump?

Edit: Or add a grounding probe.

I thought so... Heaters, manifold pump, chiller, skimmer and return pump. The display doesn't have anything electrical in the water (vortechs). Can a chiller or an external return add stray current? My first suspect honestly is the mag 9.5 manifold pump. The problem is that I can't always replicate the shock. I don't know if it has something to do with the cuts on my fingers (very small) or what. Sometimes it's a mean shock others it's just a dull throbbing.

It's more than likely the cut, especially if you only feel it in that area.

BTW stop sticking your hand in the water with an open wound......

try a different finger?

I have a maxi jet that does it as well.

What good is the grounding probe gonna do?

Could very well be the chiller since the water circulates around a titanium tube.

A grounding probe won't fix the problem, but atleast get some of the current out of the tank for now.

This is shocking news!

Wierd, I am having the exact same issue. I placed a volt meters probes in the water and there is definately voltage (millivolts) active in it. I'm not sure how much is to much but I would like to find out... Tonight I'm going to put the meter in and start unplugging.

How does it do that?

 

[crewdawg1981]

A grounding probe has negatives... I'd rather get the little shock and know somethings up.

Exactly. I think most do not realize that a continuous source of electricity is not "removed" by a grounding probe .The only thing that is accomplished is a circuit is for sure created for the current to flow along. When one sticks there hand in the water and is not insulated from any ground they become the ground. if the system is isolated from any ground I can place a bare wire from one side of an electrical outlet and no current will be present until I ground the system.

holy crap!

the SAME thing happened to me this morning!

I accidentally severed my right hand with a table saw and when I stick the stump in the sump it hurts a lot.

Weird days..... weird days

thanks for the constructive advice... not.

Very valid point. I guess a grounding probe would only be good if the owner was not intending to fix the problem and they just wanted to take away the shock that they feel.

Sadly it will not do that either.it will only join you in the completing of the circuit and may actually cause you to fell more of a shock.

? No reason to get bent out of shape? He just happened to get zapped.

As for me, I'm hoping that its just a small cut not loving the salt water... but I know better.
