An "infinity" or OL ohmmeter reading taken across the disconnected wires to a solenoid or relay coil indicates what?

A reading of "infinity" or an open-loop (OL) on an ohmmeter indicates that there is no continuity in the circuit being tested. When this reading is taken across the disconnected wires to a solenoid or relay coil, it implies that there is a break in the coil wire, preventing electrical current from flowing through.

In the context of a solenoid or relay, the coil consists of wire wound in such a way to create a magnetic field when powered. If the reading is infinite, it means that the circuit is open somewhere in that coil, confirming that the coil wire is indeed broken. This is crucial for troubleshooting since it indicates a failure in the coil that needs repair or replacement for the solenoid or relay to function.

The other options do not accurately describe the situation when observing an infinity reading. A solenoid losing power would not specifically lead to an open circuit indication on an ohmmeter. A functioning relay would show continuity across the coil when tested, whereas a short circuit would typically reflect a low resistance reading, not infinity.
