Normally-open type

Check for continuity between the terminals.

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

Five-terminal type

Check for continuity between the terminals.

• There should be continuity between the No. 1 and No. 2 terminals when battery positive terminal is connected to the No. 5 terminal, and battery negative terminal is connected to the No. 3 terminal.
• There should be continuity between the No. 1 and No. 4 terminals when power is disconnected.
