Power Distribution Relay: Testing and Inspection

Power Relay Test

Special Tools Required

- Relay Puller 07AAC-000A2A1 or 07AAC-000A1A0

Use this chart to identify the type of relay, then do the test listed for it.

NOTE: For the turn signal/hazard relay 1 input test Turn Signal/Hazard Relay 1 Input Test.














Normally-Open Four-Terminal Type A

Check for continuity between the terminals.

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














Normally-Open Four-Terminal Type B

Check for continuity between the terminals.

- There should be continuity between terminals No. 1 and No. 3 when battery power is connected terminal No. 2, and ground is connected to terminal No. 4.
- There should be no continuity between terminals No. 1 and No. 3 when battery power is disconnected.










Normally-Open Four-Terminal Type C

Check for continuity between the terminals.

- There should be continuity between terminals No. 4 and No. 2 when battery power is connected to terminal No. 3, and ground is connected to terminal No. 1.
- There should be no continuity between terminals No. 4 and No. 2 when battery power is disconnected.










Five-Terminal Type B

Check for continuity between the terminals.

- There should be continuity between terminals No. 1 and No. 2 when battery power is connected to terminal No. 5, and ground is connected to terminal No. 3.
- There should be continuity between terminals No. 1 and No. 4 when battery power is disconnected.










Turn Signal/Hazard Relay 2 (sounder)

Check for a sound from the turn signal/hazard relay 2. The relay should sound once when battery power and ground are connected to terminals No. 2 and No. 1, and terminals No. 3 and No. 1.
