I m not 100% sure but i think its open closed, like points so if you ohm it you should have low resistance then infinite, or open circuit. If you have a test light you can clip it on the leads of the coil connector, it should flash. Steady on or steady off somthings wrong.
My coil connector corroded a few years back and my truck lost fire, when i stuck the probes from my meter in the top of the conector , evevything was fine, when i turned the connector over and metered the coil side, it was dead, one of the terminals was broken inside the body of the connector.
