    Normally-Open Four-Terminal Type 

    Check for continuity between the terminals:

    • There should be continuity between terminals No. 1 and No. 2 when battery power is connected to terminal No. 3, and battery ground is connected to terminal No. 4.
    • There should be no continuity between terminals No. 1 and No. 2 when battery power is disconnected.
