SFI Control Relay Test

CAUTION: When applying direct battery voltage, ensure voltage is applied to correct terminal to prevent relay damage.
  1. Remove control relay. Relay is located behind lower left side of dashboard.
  2. Apply battery voltage across terminals No. 6 (positive) and No. 8 (negative) while checking voltage on terminals No. 1 and 2. Battery voltage should exist. Apply battery voltage across terminals No. 7 (positive) and No. 10 (negative) while checking continuity between terminals No. 3 and 4. Continuity should exist.
  3. Apply battery voltage across terminals No. 3 (positive) and No. 9 (negative) while checking voltage at terminal No. 4. Battery voltage should exist. Replace relay if it fails any test.
