Fencer Output Tip ?

[Stocker Steve]

My 12V powered fencers usually puts out about 8,000 volts on a clean fence. I have one set up that only puts out 4,300 volts - - even when disconnected from the fence. I tightened the all galvanized contacts to the fence, and to the ground, but that did not help. The terminals on the energizer were rusted so I switched energizers and batteries - - and output only changed about 200 volts. Any other tips?

Are you using the same ground when you're checking the voltage difference between the 2 chargers? My electric fencing troubles are almost always caused by faulty grounds.

my next stop would be the ground as well...

Measure the voltage from your ground terminal to earth ground.

Measure the voltage from your ground terminal to earth ground.

What should it be?

My old grounding rod was a bit rusty and I could feel some voltage in it, so I drove a new 8' galvanized rod before I tried swapping energizers and batteries. I did not change the ground wire or clamp.

How do you ID a "faulty ground" ?

Measure the voltage from your ground terminal to earth ground.

What should it be?

Less than 200 volts

With the charger disconnected, if the charger originally put out 8K and now only puts out 4.3K I would suspect the transformer has become weak--windings breaking down..

Great video. I will check across the energizer.
I thought energizers would totally, not partially, fail?

anything can happen!.. Condenser can get weak as well.

Your cows will call you Shocker Steve when you get it fixed!

Is there a capictor in there that has become week. I think that is what makes the chargers pop.

As low as possible but less than 200 volts is a pretty good ground.
