Relay test
4-pin relays
1. Remove the relay.
All relays are tested in the same way.
2. Check continuity between pins #1 and #2.
3. Check continuity on pins #3 and #4.
4. Apply battery voltage between pins #3 and #4 and check continuity between pins #1 and #2.

5 pin relay
1. Remove the relay.
All relays are tested in the same way.
2. Make sure there is continuity between pins #3 and #5, #2 and #4, and no continuity between pins #1 and #2.
3. Apply voltage from the battery to pins #3 and #5 and make sure that between pins #2 and. No. 4 has conduction, and there is no conduction between contacts No. 2 and No. 4.
