Can you test relays with a power probe?

The Power Probe 3EZ is a Digital Voltmeter that provides diagnostic power with the flip of a switch. This tool simplifies the testing of fuse boxes, verifies correct operation of motors, lights, relays and wires.

How do you test a relay with power?

Touch the leads across the switch pins. A normally open relay should read open or OL. Energize the electromagnet coil with a 9-12V battery across the pins. The relay should make an audible "click" as the electromagnet coil energizes and closes the switch.

What is the best way to test a relay?

The only tool required to check a relay is a multimeter. With the relay removed from the fuse box, the multimeter set to measure DC voltage and the switch in the cab activated, first check to see if there are 12 volts at the 85 position in the fuse box where the relay plugs in (or wherever the relay is located).

How do you test a relay with a tester?

Take the leads of the multimeter and connect them across the coil terminals of the relay. For a normal coil, the multimeter should read anywhere between 40Ω to 120Ω. If the coil is damaged i.e., it is open, the meter shows out of range and you have to replace the relay.
