Still not sure what caused it; it was the first time this had ever happened, and the product was due to EOL, so the CEO told us not to waste time diagnosing. Charge the capacitor by using the sense current the meter puts out when set to ohms. A parallel diode is required if voltage is reversed momentarily, but using a nonpolarized capacitor is better practice.

Polarized Capacitor in reverse direction??
Tried to edit out the beginning and end with the buggy youtube editor because I was too lazy to load it up in avidemux. Back at my first job we used to do just that for fun, take an electrolytic cap, put it on some stiff leads, slide it along the floor under someone else's bench, and turn it on with reverse voltage from a lab power supply. Hot Network Questions. Some also blow up when you put them in backwards. I replaced it with an electrolytic. Unbelievable, that would happen with only about 20W of AC input not very efficient at that low load.
