[pdf] Measure continuity between the common terminal and the normally open or normally closed contacts using a multimeter. For critical applications, measure contact resistance using a micro-ohmmeter or the 6 V/1 A method. This comprehensive guide will delve into the intricacies of using a multimeter to effectively check a relay, providing a step-by-step process. How do you test a relay with a multimeter? Check the resistance of the coil and continuity between the terminals of the switching side using the multimeter. Resistance of the coil should fall between 50 and 100. It should produce no sound. A multimeter is a diagnostic instrument that measures electrical properties such as voltage, current, and resistance. Checking your vehicle's relay is a straightforward procedure that does not require a complete kit.
