Me again trying to repair this electric fence unit...
Seem no problem redesigning the charge cap charger, and fire cirquit.

But...

I have earlier repaired an electric fence unit in which a microcontroller=
 adjusted the charge according to the load. =
 (Trial-measure-increase/decrease style)  That one was a whopping 9 Joule=
 per pulse unit. =20
(If anyone wants to know, it was only the FET switch that was blown in that=
 one.  They had stupidly used a 600 V part, operating at about 620V peak @=
 full load and 230V supply.  Replaced with it=B4s 800V rated sister.)

Most units i have seen is 1.5 to 4 Joule.

The one i repair i calculated to 6 Joule capacitor stored energy.
Scaring, it has room for another equally large capacitor, yeilding 12J!

It is possible this IC incorporate some clever function for load adaption,=
 but it seem that would be an add-on ckt to connect to 3 unused pin=
 connectors.  Maybe only used with the larger capacitor bank.

Now, is it recommended to just shoot 6J in every shot...?  I mean personal=
 safety.
I know for sure i will keep my hand at safe distance, as the 9J machine blew=
 2W carbon film resistors like New year bombs when i tried to test it, and=
 wire wound types arched...

BTW it is a TORO model 6000 made by IAAB
I searched but could not find the manufacturer on the web.
