RELAY REFERENCE CHART
Normally-open type
Check for continuity between the terminals.
Scheme 2
- 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. (Scheme 2): Checking Continuity Between Terminals - Normally-Open Type
Five-terminal type
Check for continuity between the terminals.
Scheme 3
- 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. (Scheme 3): Checking Continuity Between Terminals - Five-Terminal Type
