Electrical Charge from Jabeo Gyre

[DBUK]

hi all I understand that salt is a conductor to electricity however my Jabeo Gyre pretty new and has no loose connections visible but I keep getting a electric reading on my conductivity pen when I hold it in the water and the pump is on. when I turn pump off with all other equipment on, im not getting any electrical reading on the pen. is this common with these pumps that they appear to release a electrical current into the water. and what impact would this have on my fish ????

thanks for the help!

The Jabeos are hit or miss. What readings are you getting? One way to solve this is use a grounding prob. Best 7 bucks you will ever spend.

hey Bmwm235i its just a electrical conductivity pen which lights up and theres a electrical current, so I put it in my salt water and it light up while the Gyro was the only thing on in tank. and once I pulled the plug from the gyro waited 2 mins the pen didn't light up when I tested the water again.

and yes a friend has said about the grounding probes so they are really good and will this solve the issue with the Gyre

Pen testers are a quick safety item, if it is lighting up grab a meter and check for voltage. Here is a picture with my Fluke pen touching the glass on my tank. Notice how it is lit up.

oh I see so it maybe not hardly anything in a way of strong electrical current. its just the pen it just picking it up. I see if I can borrow a meter tomorrow.

ok thanks Alton

This Fluke pen, as its lighting up I assume this is showing the conductivity is live, I assume this is in the water itself. Do fish get effected from this stray current or not, due to the fish not having an earthing? Also does a simple grounding probe sort this issue completely?

Thanks for showing this. We call these things "Widowmakers". They are good for.. well.. not much of anything. They react to an electrical field, not necessarily current. By just using a pen detector like this you won't know if what the gyre is putting into the water is a relatively harmless induced voltage or if your motor has a live electrical conductor touching the water.
