    Are there any manuals or books available that would tell you how to troubleshoot and repair electric fence chargers. Have found a couple of companies that do the repair but the shipping ends up prohibitive and DH likes to tinker with repairs ... engineer in former life ... but needs a 'how to' manual or book to get started.

    Suggestions?

    You'll have to search hard. Product liability makes it almost a given that giving out such info would get people killed. The circuitry is probably fairly straightforward with a timer, RC oscillation and step-up transformers or circuitry, and some decent isolation and stray voltage protection. If he knows electronics, making a schematic based on the parts and wiring should be possible. The big danger would be the caps.

    Check at your local farmers' co-op or supply outlet to see if they repair chargers. Service guy may work him through it. Local guy has repaired mine 2-3 times. However, one time I found the charger blown off the wall. Absolutely nothing he could do for it.

    Before starting repairs though, double check you have good fuses in it.

    Mine is a 9.9j, and at full strength I guarantee it will get your attention.

    The closest place that does repair is about 35 or 40 miles from us on 'slow' roads ... an hour's drive.

    read up on basic electronics, a few trouble shooting tools (maybe around $2000) find good parts suppliers and have at it...i don't know of any book specifically for fence chargers,,,,but he could be the first to wright one..

    Thought mine was burned up one time (no reading on the test meter) until I found a busted insulator and the wire against my welded wire fence. I'm embarassed to say that by then I had bought another energizer. Oh well, now I've got a spare.

    A quick test would have been to take off the hot wire on the charger and then check what juice it is putting out. I've learned when mine is all the way to the right (even off the green), I have a short somewhere.

    Ken, thanks for the advice, next time I'll do that.

    I have searched diligently without success to find schematics. Farm stores just replace boards and complete circuits. Parts are difficult to access also. For years i bought the same type of unit so that I could scrounge parts from the failed units but I do not do that any longer. I now buy units with at least a two year warranty and divide the purchase price by 24 and that is my costs of ownership. The is a schematic on the internet of how to build a fence charger from an automobile ignition system if you search for it.

    decades ago mother earth news had plans for one with auto coil...i made a few.....they did ok....medium hot....and they could be repaired....hmmm perhaps someone should come up with a modern home built......for all of us...

    What I would do (if only I had more spare time!) would be to read and comprehend electronics (transistors, diodes, etc etc) and then un puzzle the schematics. Some, though, are too complex to be fixed except by a professional (or replace the circuit board/special part). There are instructions online on how to make your own fence charger, that might help.
