Pump Motor Relay

With relay disconnected, use DVOM to check continuity between relay terminals No. 4 and 5. See Fig 1. Continuity should not exist. Apply battery voltage across terminals No. 1 and 3. Continuity should exist between terminals No. 4 and 5. If continuity is not as indicated, replace relay.
