I am working on an electric fence energiser and trying to figure out what the issue is. I am testing all of the components and have taken these capacitors out of circuit to measure them. I am unsure what J signifies though as the readings I get on a multimeter don’t seem to align with uf, nf, pf etc when I put it into a conversion page.
To be able to replace them with the same value I need to work out what value j is.
