Fencer question?

greenspun.com : LUSENET : CountrySide Family : One Thread

I have an old Sears fencer, the kind that uses a three prong pulser. Ok, I thought the pulser was the problem, but it wasn't. Then upon closer inspection I see what I think is the problem. Now bear with me here! ;-) Coming off the insulated hot, the wire goes through two multi striped, (ceramic???)cylinder thingies about half an inch long. There are smaller ones as well, 1/4 inch, located in other locations. What are those? I'm assuming they are in essence, 'breakers'. Meaning if they get too hot, they crumble???? One of the small ones is fried, I'm wondering if I can bypass it, and resolder? I mean, not only do I have a breaker box, but the fencer is on a surge breaker. So??? Whatcha think?

I also have an old Blitzer, but I haven't looked that close at that yet.

Come to think of it, these are probably to protect the fencer itself from a power surge. If lightning hits the wire.....these would fry before the guts of the fencer...?

if I remember correctly, those "thingy's" up the voltage, and lower the amps, ,so it shocks and doesnt kill.. "IF" I'm remebering corectly,, then you could bypass the bad one, which would just lower the shock value. But still should do the job.

Patty make for sure you have it grounded properly! Could it be the ground that is fried?Hard to help with out seeing it. Good Luck!Ed C

I'm just testing the fencer itself. I have a 12 foot solid copper ground. It has always been sufficient. I'm talking the innards of the fencer, you know?

Stan, I guess I was way off, those change voltage? Urg. Maybe I'll look and see if I have an old one with the same "part" and just replace it......?

why not jsut bypass the bad one. Still should have enough shock value

You're sure that's safe?! I just want to make sure. :-)

as long as the solder job is good,, the only thing I can see that would be changed, is teh voltage,, the amps should still be low enough not to hurt. CAn always give a guy a couple beers,, and have him do the "pee test"

Patty,

I believe that the crumbly things your are talking about are carbon resistors that can be purchased at most radio shack stores for about 10 cents each.

I believe their intent is to limit the current going to the fence, and probably overheated due to many hours of working into a shorted fence....

You might still be able to see the color bands on the side of them to find out what value the resistors were. (brown, red, orange, yellow,green, blue, violet, grey, white, black equal value 1 to 9 plus 0 with the last band a multiplier of 10 to the x power.) Otherwise, sears has a nice customer service web site that might have a schematic available where you could identify the parts used.

Otherwise, my advise would be to add wire and short them out inside the sears box, and then add and aftermarket current limiter between the sears box and the fence...

I always wondered how my electrical engineering degrees would come to use raising sheep....makes me feel that 6 years of college was not wasted if this works for you.

I think a long blade of grass would be a lot safer than the "pee on the fence" method.

Hey thanks, carbon resistors, (slapping forehead) I should have known! BTW, are you insinuating the fences are grounded too much, IE I don't check them enough? Well! I never!

Oh, and I have a tester.....but I also have a funny hot wire story.

Now, Gary, as to your frantic questions. Not to worry, the other site will be up and running in no time! But don't be a stranger, ya hear? :-)

Now look! See? It's up.
