Radiator Cooling Fan Motor Relay: Testing and Inspection

Fig. 29 Relay Tests:

1. Measure for continuity between terminals A and B then between C and D, Fig. 29.
2. Continuity should exist between terminals A and B when battery voltage is applied to terminals C and D.
3. Continuity should not exist between terminals A and B with battery voltage disconnected.
4. Continuity should exist between terminals C and D.
