Shock from earth bar on battery fencer

the fence line is reading 7.6, the earth bar fluctuating between 0.2 and 0.3

I know the ones,

I threw the earth bar that came with it away and use an old bale spike instead. Your issue could also be that the ground has become too dry. You could wet up the ground with a few buckets of water to take you out of a hold

When you say you get a shock, is the earth bar in the ground at the time?

Is the wire fence earthing somewhere

If you have a drain/ shoke in the field where you are using the fencer, drive your earth bar into the wettest part of it & use a bit of long wire to get you back up the bank to the fence wire.

Will be a big help, if struggling in drier ground for a earth.

On the earth, mains anyway, if you touch the earth rod with one hand & place your other hand on the flat of the ground, if your getting a shock from this, your earth is not good enough.

I've five 1 metre galvanise earth bars for mains here, all connected with galvanised wire, 3 metres apart, with insulated galvanised wire back into the unit, in damp ground, usually wet, & still get a tingling shock.

I think getting a goodearth in the last month has been more difficult as ground is dried out, despite more rain recently. Only wetting the top a bit, thankfully.

You can test the earth bar with the Multimeter if you want to!

To do so you have to first earth the electric fence wire (the wire to fence the cattle). Do this a good bit away from the fencer and make sure the it's earthing the fence so use a bar to earth it.

Then go back to your earth bar for the fencer, set the multimeter to read Voltage the highest DC voltage (on the cheap ones it probably only goes to 500V) then measure the Voltage between the earthbar and ground. You should be reading very little <100 Volts, if you are reading a couple of Hundred volts then it's down to the earth bar (as pointed out before) OR it could be the wire you are using. There is the off chance that some of that corded electric fence wire just isn't up to the job. the cheap stuff with 4 strands or less over a short distance is just not capable of transmitting all the power from the fencer so you end up with feedback on the earthbar. The solution for which would be better quality wire or just use a big earthbar and sink it well into the ground. Those pokey little bars that come with the fencers are just not up to the job especially if you have sandy dry soil types, you need a heavy bar going at least 20inches into the ground to get a true earth. that's why it's back to my original recommendation of a bale spike for a mobile fencer

I have a bit of high tensile wire going down into a deep trench of water. I connect the earth of the battery fencer to this.

That might ressurect the dead
