So, the capacitor is 144 uF, but the range on the can is 107-129 uF. I’m surprised that it would fail _high._ It takes more than 5 seconds, almost 10, for the meter to report a result. It shows a moving bar (“working”) and nF for the scale, then autoranges up to the uF scale, then reports 144 uF. I see someone saying that leaky capacitors test slowly and end up being overcharged by the tester and thus can read high (even though the normal failure is to show low capacitance).
Btw, this cap was soldered on, no removable lugs. There was barely enough room to reach in with a soldering iron and it took some shenanigans to get something in there to make sure it was discharged.
