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

RJ already done the research for you and found the resistor for you so why not order two of them and just replace them.

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

Right now you are testing to find out if the main filter cap will be charged up to full Voltage or not WITHOUT THE LOAD (Transformer is not in place) so those HER-208 will be fine.

Good catch about the Vdrops of 230V on the fuse, I did not see that before, may be bad fuse...

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

That is fine, so for the cap not to charge up basically instantly without the load when applied the power then it has to be those resistors, diodes since it just simple half wave rectifier circuit.

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

The reason I have you checked the resistance, NOT ESR, is to find out if has leakage resistance that is bad enough to cause the problem or not.

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

What is the resistance and capacitance reading of that 16uF 400v CAP?
Make sure to discharge it first.

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

Put the dc Volt meter probes to the two legs of the 22uF cap to measure the Voltage on the cap.

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

You need to check the DC Voltage between its two legs to make sure it is charged up the firing Voltage of the DIAC or not as I suggested earlier.

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

I have a feeling that the 22Uf cap may have leakage resistance so the Voltage never rise up high enough (the charging resistor is 2.2M) for DIAC to come on, or that 2M is way above 2M. It is just...
