Wish I had an answer. I'm having problems.
Bought a Zareba LI100 low impedance 100 miler rated at 6 joules and 13,300 volt max output 2 years ago for $200. 2 ground rods about 10' apart by the drip edge of the barn so they are usually in mud.
I'm running a double strand of hot wire around a part of a corral and then on around part of the pasture so there is about 1 1/2 miles of wire max. This controller should be overkill.
This winter, found it wasn't working, sent it in to Zareba who put a new board in it for about $85.
Earlier this summer while working near one section of the fence, bumped it with my elbow and the shock was enough to leave my arm part numb for a few hours. Great I thought.
This summer the giant ragweed probably got away from us. Horses respect the wire but the burros got out a couple weeks ago. Cleared a couple hundred yards of weeds from the wire around the corral but not getting much of a spark still from the wire. Bought one of those Zareba digital testers and replaced the underground insulated wire going from the charger and under the gate.
Put the tester on the charger by it self and it maxes out the tester. Put the wire on, and about all I get is about 1000 to 1200 volts which drops down 200 to 400 volts. This is at the charger and the start of the wire. One of two strands is totally dead. I know further down the pasture about an 1/8 mile, ragweed is still touching the wire but I thought it should have more voltage up close by the barn but apparently not. We had rain last week so it was plenty wet.
Another oddity noticed last weekend, one of the ground rod wires is bare fence wire, when I bumped it close to the barn tin, it started sparking against the tin.
Anyone have any ideas other than cutting those 6' tall ragweeds with trunks like trees. Then the wind blows them against the wire. I'm really disapponted that one short somewhere will affect the whole fence even close to the charger.
