RELAYS TEST REFERENCE CHART
Normally-open type A
Check for continuity between the terminals.
Scheme 53
- 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.
