Starter Relay: Testing and Inspection
STARTER RELAY CONTINUITY CHECK1. Remove the starter relay from the relay box inside the engine compartment.
2. Set an ohmmeter, and check that there is continuity when the (+) terminal of the tester is connected to terminal 4 of the starter relay and the (-) terminal is connected to terminal 2.
3. Next, check that there is no continuity when the (+) terminal is connected to terminal 2 and the (-) terminal is connected to terminal 4.
4. If the continuity checks in step 2 and 3 show a defect, replace the starter relay.
