My parmak 6 fence charger quit charging. I replaced the battery; still no charge. It is only 3 years old. Is there any other things I should check before replacing the whole unit?

The voltage out to the fence is too high for a regular multimeter to read.
See if this general application video helps.
9 Troubleshooting your Electric Fence

1. A solar powered electric fence energizer usually contains a battery for energy storage. The solar panel collects the energy from the sun and charges the battery. Lead acid batteries, which are used in solar fence chargers, typically last around 3 years, or around 1,000 days of charging.

Grounding is very important for an electric fence, especially in dry soil. I normally drive 2 or 3 - 6 foot long ground rods 10 feet apart then join them all together and run that to the charger using double 14 gauge or 12 gauge copper wire. You can get the roda at Tractor Supply.

The click is the transformer carrying current. If the unit doesn't click, unhook the fence from it and turn it on. If it starts clicking it is a short on the fence. If it doesn't then the unit is not working. contact parmak and they can service it or sell you a replacement circuit board which is the most common failure.

I would first start with the battewry, 2 year run on battery is pretty good. You can go online and find replacement batteries or go to place of purchase and check with them.

if the unit is not produceing a charge during daylight then it is the unit. the DF-SP-LI will produce full power under sunlight alone. test the unit with the fence unhooked.

With the fence connected or not?. with; then disconnect and turn it on again . if it works fence problem if not unit problem. with-out; unit problem . most likely PCB

try going to parmak web site

We have one of these, it's great.

I would try removing the battery and charging it with a proper low-amperage charger (1 amp). Your battery will either be 6 volt or 12 volt, just be sure the charger matches.

Also check the ground rod and all wiring connections.

I WOULD THINK SO BUT THE BLACK MAT BE THE POS. AND YOU MAY BURN UP THE CHARGER IF HOOKED UP WRONG BUT OTHER THEN THAT YOU HAVE GOT I THINK
