Power and Ground Distribution: 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 input test Turn Signal/Hazard Relay Input Test.














Normally-Open Four-Terminal Type

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

Diode type





Five-Terminal Type

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 power is disconnected.
