MPI Control Relay Test: Scoupe

  1. Remove control relay, located under left side of dashboard, near instrument panel. Connect 12-volt battery across relay terminal No. 2 (negative) and terminal No. 4 (positive). See Fig 1 . Using ohmmeter, check continuity between terminals No. 1 and 5. Continuity should exist until voltage is disconnected.
  2. Reconnect battery voltage between terminals No. 2 and 4. Check continuity between terminals No. 3 and 5. Continuity should exist until voltage is disconnected. Replace relay if it fails any test.
