From: Chris F. on 23 Jul 2008 19:08 Any idea as to the value of this cap? The markings on it are: 53D603 A1328-1/K14 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 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. -- Dave M MasonDG44 at comcast dot net (Just substitute the appropriate characters in the address) Experience: What you get when you don't get what you want

You indicate that the cap might be a Siemens unit. It would surely help if the OP come back and indicate the manufacturer of the capacitor. -- Dave M MasonDG44 at comcast dot net (Just substitute the appropriate characters in the address) Experience: What you get when you don't get what you want
