How To Check If A Glow Plug Is Bad. Regular resistance checks are key. Record and compare the readings to specs. If one or more of the glow plugs gives an unusually high reading, it should be replaced. If you or a customer has spotted a potential sign that their glow plugs are faulty, or at the end of their lifespan, the next step is to accurately establish whether replacement plugs are needed. It could be an issue with the glow plugs, the glow plug system (module, relay, or voltage supply). Keep in mind that a glow plug can become faulty because of excessive carbon buildup. Measure each plug individually when the engine is off and cool. To test glow plugs, set your multimeter to resistance mode. Testing glow plugs involves doing a preliminary visual inspection, using an infrared thermometer to test them, and then using a multimeter to check their resistance. A glow plug is essentially a resister and is tested the same way: Disconnect wire to the plug. For accurate diagnosis, consider using a specialized glow plug tester with an ammeter and switch. Clean the thread of the. Thankfully, this is easier than ever to do, and can usually be achieved without removing the glow plug from the engine.
