How To Test & Repair An Electric Fence Energizer | Kencove KF13000 or EK13 Repair

I have a Parmak SE5 that is acting very similar to this one. No clicking, zero output. It worked great for a few days before it just stopped.

Things like that can and do happen. Anything inside can cause it to happen in a parmak, they have 3 circuit boards inside that model and all of them have to work right together in order for the whole unit to work correctly, so it's hard to know what's wrong with it exactly without being able to test things out.

I just started following you last week or so. I've been wanting to get a charger here at the house. We are leaning towards acdc just if the power goes out it still works. Typical brands at Rural King, Patriot, Gallagher, Country Way, ect. Not sure which one to go with, none have good reviews.

[@FencerFixerRepairLLCKansasCity]

Gallagher and County Way would be the ones to look at. Gallagher is top notch stuff. Country way is just a private label Power Wizard made by Agratronix in Ohio

Patriot is a cheap throwaway brand and no parts are made for their units. They're like a toaster, when it breaks outside of warranty, you trash it and buy another one.

@@FencerFixerRepairLLCKansasCity ok, thank you very much for your advice. Are the solar chargers pretty good or try to stick with ac or dc or acdc both?

A shorted turn in the primary would still read ohms in the acceptable range. Doesn't mean it is 'good.' One shorted turn will render it useless. Ring tester, impulse tester, or something like that to know for sure. I would guess the cost of the transformer alone would make a repair nearly unfeasible in most cases. Would be good to be able to definitively rule it out from the beginning.

On this type of device and how they run and operate, the primary on any low impedance electric fence charger the primary on the transformer is just a closed loop internally to allow the energy from the board and capacitor to be able to discharge through it and that's it. So of it reads to high, then it cant take any discharge through it. So 100% of the time when the transformer in an electric fence charger primary reads 0.1 to 1 ohm, the primary is good. If it starts reading over that, which most of the time when the primary is bad it'll read open or in the Mega ohm range, then the board and capacitor can't discharge their energy through a high resistance. This is basic electric fence charger transformer operation 101. The secondary side will vary in readings from brand to brand and model to model based on the winding and how the manufacturer wants the unit to perform and what kind of KV reading they're after. Also, It doesn't sound like you work on many of these. The cost of the parts are very reasonable vs a customer having to buy a new unit. Unless a person charges them way too much for parts and labor. We're pretty fair and work on 1,000's of fence chargers every year.

@@FencerFixerRepairLLCKansasCity I don't work on them. I was in sound and video monitor repair in a past life. I acquired a parmak se-5 on Ebay completely disassembled ($20) with all 3 boards present and no xfmr cracks. I want to attempt a repair to keep deer out of my garden, and was checking out videos. Seems they have a strange proprietary design. The optoisolator IC on the incoming power board raised some suspicious red flags of some over engineering. We'll see how it goes, even if just a fun waste of time.
