Any idea as to the value of this cap? The markings on it a

0043H550
It's about 2" wide and 1" thick, and comes from a Co-Op brand electric fence
power supply. It tests dead-shorted.


It's a 60,000 uF electrolytic, but it's so old that I can't decipher all of the
numbers to get the voltage rating. It's likely to be a special unit, so the
numbers are only meaningful to the OEM.

Unless someone else has an old Sprague catalog to determine the voltage rating,
you'll have to use a little common sense. Remove the bad capacitor and
temporarily wire in a high voltage capacitor of a few hundred uF and measure the
voltage developed across it. Add a safety factor of about 20-30% of that
voltage.

You probably won't find that exact capacitance in a new capacitor, so use
something close... like 62,000 uF, which is more likely to be a standard value.
