Go to the highest ohm scale on an analog multimeter touch the positive lead to the wire on the condenser, and negative on the condenser case. (this will put a small voltage into the condenser) remove the test leads and reverse them (negative on wire, positive on case and if the condenser isn't shorted or open you will get a deflection kick on the needle of the multimeter, due to the stored electricity in the condensor. The kick may be small depending on the amount of voltage the multimeter uses in the high ohms position, like 0 - 100K ohms. My Simpson 260 has a 100K position and my Tripplett has a 250K position. Caution, never test an electric blasting cap with a multimeter! this small voltage could detonate an electric blasting cap
