How do you test a 3arr3 bl6tw4 relay?

To test a 3arr3 bl6tw4 relay, first ensure the relay is disconnected from power. Use a multimeter to check the coil resistance by measuring across the coil terminals; it should show a specific resistance value as indicated in the relay's datasheet. Then, apply the rated voltage to the coil while measuring continuity across the switch contacts; they should close and indicate continuity if the relay is functioning properly. Finally, if available, test the relay under load conditions to verify its performance in the circuit.
