RELAY POWER TEST
Normally-open Type A
Check for continuity between the terminals.
Scheme 69
- There should be continuity between the No. 1 and No. 2 terminals when power and ground are connected to the No. 3 and No. 4 terminals.
- There should be no continuity between the No. 1 and No. 2 terminals when power is disconnected.
Normally-open type B
Check for continuity between the terminals.
Scheme 70
Scheme 71
Scheme 72
Scheme 73
Scheme 74
Scheme 75
- There should be continuity between the No. 1 and No. 3 terminals when power and ground are connected to the No. 2 and No. 4 terminals.
- There should be no continuity between the No. 1 and No. 3 terminals when power is disconnected.
Five-terminal Type
Check for continuity between the terminals.
Scheme 76
- There should be continuity between the No. 1 and No. 2 terminals and no continuity between the No. 4 and No. 2 terminals when power and ground are connected to the No. 3 and No. 5 terminals.
- There should be continuity between the No. 2 and No. 4 terminals and no continuity between the No. 1 and No. 2 terminals when power is disconnected.
