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

Main Relay Test:

- Remove main relay.
- Using an ohm meter, check for continuity between terminals 1 and 2 of relay.

Continuity should exist.

- Check for continuity between terminals 3 and 4 when battery voltage is supplied between terminals 1 and 2.

Continuity should exist when voltage is supplied

- Check for continuity between terminals 5 and 6 when battery voltage is supplied between terminals 1 and 2.

Continuity should exist when voltage is supplied
