condensers are capacitors. test them with an ohm meter.
short the pigtail to the body to discharge it.
set a meter to Rx1
put leads on the pigtail and body. On an analog meter, the needle will swing from 0 ohms to infinite. On a digital it will go from a low reading, probably auto range a bit, then indicate infinite.
Condensers that read infinite all the time are open, ones that read 0/low and never increase are shorted.
