Beetronics electric fencer schematic

[orion4567]

Hello, Would anyone happen to have a schematic diagram for a Beetronincs electric fencer Model SPD-9701? These fencers were made in Edmonton, Alberta, Canada.
Thanks in advance.

tbh I was thinking the same thing for some reason.

WTF is it? Electric fence charger?

pictures? of damage?

47.5Kw?? must be chinese ratings!
either that or buy a couple to protect the u.s. and european borders!

Re: Beetronics electric fencer schematic

Yes , but it's one Joule/second .. I like to repair such a device if he put clear images , since I never saw one but in testing devices .
Doing some research , i got those related pictures ..

I have attached some pictures of the PCB.
Of note I have repaired the unit and returned it to the owner.

Re: Beetronics electric fencer schematic

so what was it?

first thing i noticed are the 6A diodes too close to the board - obviously well over-rated as no signs of heat,
and the associated dark brown resistors - an obsolete type known for drifting and absorbing moisture

Re: Beetronics electric fencer schematic

well, there were three to-92s that seem to have been reworked...

hmm... interesting design.

anyway good job, didn't need a schematic after all!

Re: Beetronics electric fencer schematic

It was a high resistance connection on the 12 volt battery terminal connection. Mechanically it was sound! An easy fix but I am disappointed in one way. I would have been interested to find out exactly how this particular system delivers 8,000 volts as it was different from the last electric fencer I worked on.
Cheers everyone for weighing in.
