Google for "electric fence schematic" and take your pick.

I'm particularly looking for one for a Blitzer - model 8555A, but any
of the SCR driven ones should help. It contains a circuit board with
a SCR and another diode that works with the SCR (is that a diac?)
Has a capacitor discharge to a high voltage transformer.

This is probably a fencer from the 90's. The company was sold to
Zareba who no longer offers parts or a schematic.
