Mixture Control (MC) Solenoid
- Start engine and listen to MC solenoid for clicking sound. If clicking is present, solenoid is functioning properly. If not, turn ignition off. Disconnect MC connector.
- Turn ignition on. Check for battery voltage on Black/White wire of MC solenoid harness. Battery voltage is supplied by 15-amp fuse in fuse panel. Fuse also supplies voltage for ignition and remaining solenoids.
- Turn ignition off. Using an ohmmeter, check resistance across solenoid terminals. Continuity should exist; however, zero resistance is an indication of a shorted solenoid.
