The glow plug is an important auxiliary heater in the ignition system of the automobile, and it is an auxiliary equipment during the starting process of the diesel engine. If the glow plug is abnormal, it is difficult to start or takes a long time to start in winter or when the temperature is low, the cold start smoke is large, and the preheating does not respond. If you want to measure the quality of the glow plug, it cannot be seen from the outside. You need to use a multimeter to measure its resistance to judge. Generally its resistance is less than 1 ohm.

If there are resistances, it is good. If several resistances are basically the same (the error rate is less than 2%), it is 100% good. If there is no resistance, it is a short circuit.
There is the other method, turn on the power for 20 seconds (without starting the engine), and then touch the glow plug with your hand, if it feels warm, it means the heat glow plug is under normal operation, otherwise it is in an abnormal operating state.
