Main Relay (Computer/Fuel System): Testing and Inspection

1. REMOVE EFI MAIN RELAY

2. INSPECT RELAY CONTINUITY




a. Using an ohmmeter, check that there is continuity between terminals 1 and 2.
If there is no continuity, replace the relay.
b. Check that there is no continuity between terminals 3 and 5.
If there is continuity, replace the relay.

3. INSPECT RELAY OPERATION




a. Apply battery voltage across terminals 1 and 2.
b. Using an ohmmeter, check that there is continuity between terminals 3 and 5.
If there is no continuity, replace the relay.

4. REINSTALL EFI MAIN RELAY
