Checking Relay Continuity:

2. Attach the Battery Positive Terminal to the No. 6 Terminal and the Battery Negative Terminal to the No. 8 Terminal of the PGM-FI Main Relay. Then check for continuity between the No. 5 Terminal and No. 7 Terminal of the PGM-FI Main Relay.
- If there is continuity, go on to step 3.
- If there is no continuity, replace the PGM-FI Main Relay and retest.

3. Attach the Battery Positive Terminal to the No. 5 Terminal and the Battery Negative Terminal to the No. 2 Terminal of the PGM-FI Main Relay. Then check that there is continuity between the No. 1 Terminal and No.6 Terminal of the PGM-FI Main Relay.
- If there is continuity, go on to step 4.
- If there is no continuity, replace the PGM-FI Main Relay and retest.

4. Attach the Battery Positive Terminal to the No. 3 Terminal and the Battery Negative Terminal to the No. 8 Terminal of the PGM-FI Main Relay. Then check that there is continuity between the No. 5 Terminal and No. 7 Terminal of the PGM-FI Main Relay.
- If there is continuity, the PGM-FI Main Relay is OK.
- If there is no continuity, replace the PGM-FI Main Relay and retest.
