I have a Gallagher mb150 mains energiser on a 4 acre field and I’m getting 8000v where the live wire connects to the fence, but this then drops to nothing about halfway round. I’m using poly wire which isn’t the thickest 2mm at a guess and I haven’t joined the fence in a loop yet are these my two main issues . I presumed it wasn’t an earth problem as I’m getting the power in the fence at the start

What do you mean sorry

If it's dropping part of the way round you've got a broken wire or a bad connection somewhere.
I don't like poly wire as a carrier as it burns out on joints, knots and connections.
Look for sparks or black bits.
Anywhere you hear it clicking is potentially a burnt out spot.

Can you post a picture of the fence, ground and energizer?

Need to walk round after dark and check for sparks and clicks.

I am losing a lot of volts through new grass just now. I am putting another earth stake in this morning to see if that will help.

Just walk around with one of these and find where you loose the volts…

I have two fence testers with LED displays both impossible to see on a sunny day, so two options, test at night or put a cowl over the meter. The cowl didn't really work until I tried sticking my head inside a black plastic sack like an old fashioned photographer. Worked better until the wind blew the sack across my downward line of vision and I walked into the fence. The fence was working.

If you get some galvanised stranded wire or even some high tensile, you won't have any breaks and other faults are easier to find.

We use high tensile wire for carriers.
The tiny conductive threads in poly wire just can't hack it on anything permanent, fine for temporary divisions but that's it.

I find the electricity kills the vegetation off quite well, but if a section is switched off for a while allowing the grass to grow up too much it is often overwhelmed when it's switched back on until it gets it zapped back again.
For that reason I rarely ever switch sections of fence off.

Has that solved your problem?
Will let you know when I get it on

How long?! I have fences miles long with polly wire

A lot of leakage through vegetation here. So I have the power distributed through the top wire, then take a lead off that for individual paddocks with stock in them. It's more work, but it does keep hill sheep in. Fed up with escapees. I hung a strip of scrap aluminium below one gate they were getting under with baler string, then attached a hot wire from the fence. That fixed 'em!
some poly wire only has 3 strands of wire in it some has more also some is made differently so the wire sticks out of the plastic more so the animals are more likely to get a shock also the wire is not so tight so less likely to break
Will let you know when I get it on , it’s not come yet
i think it was 1.6mm thick and it said it was suitable for short to medium fences and I have a 600m run of it but at about halfway the voltage drops right off but it has hight power at the start so I guess this is down to resistance in the wire
