My electric fencer

[jerseycowsman]

Just checking something here as my fencer appears to be playing up. The green is definitely the earth and the red is definitely the fence wire?
What’s the black in the middle for, whilst you’re here? Is that right?

Black is lower output

Black is the test earth to measure if the fence earth is good.

Lower output is my vote.

Should be an online manual if you Google it.

With Will on this. Lower output usually a smaller lightening bolt.
