How do you check mb83865 relay?

To check an MB83865 relay, first, ensure the circuit is powered off for safety. Use a multimeter to measure the resistance across the relay's coil terminals; a typical reading should be within the relay's specified range. Next, apply the rated voltage to the coil while monitoring the relay's output terminals for continuity. If the relay clicks and the continuity changes from open to closed, it’s functioning properly; if not, it may need to be replaced.
