Default Re: Repair Fence Energizer SS-1000E Fi-Shock

I drew a schematic, instead of cleaning my house. Not all part values known but this should help figuring out things.

It looks like a slow relaxation oscillator making pulsed DC.
The transformer back-emf shuts off the SCR, so not possible to use a light bulb in place of the HV transformer to test things.
