In what ways would a relay fail to perform? Broken or unconnected wiring Relay coil fails to move Spring is broken Contacts weld together How could we increase the probability a relay would operate successfully? Wiring protected in conduit Spring clamp terminals, insulation displacement (IDC) terminals or proper screw torque Proper fusing to limit relay coil voltage Diode protection on relay coil to limit back EMF (voltage) to signal source Periodic testing of the circuit

Solution

Relay fail to perform due to all reasons like broken or unconnected wiring, relay coil fails to move and when soring is broken and when contacts weld together.
