OTC 3673 Diesel Glow Plug Tester

Product Information

If glow plugs are causing the engine’s problems, the engine should run normally after it warms to operating temperature. Normal signs of glow plug failing would be engine cranking over but not starting and smoke coming from the exhaust, it may eventually start with a lot of smoke. It has probably been starting rough for a while and the air temperature has now dropped. The engine should start with a small squirt of Easystart (Ether) in the air intake. If one or more of the glow plugs gives an unusually high reading, it should be replaced. However, we suggest that you replace every plug – not just the one that appears to be faulty! If you provide content to customers through CloudFront, you can find steps to troubleshoot and help prevent this error by reviewing the CloudFront documentation.

In essence, a multimeter is a box of electronic circuitry that can be used to run a variety of tests on electrical wiring or devices (hence its name ‘multimeter’: multiple measurements). You may be extremely familiar with your model of multimeter already – but if not, here is a refresher: Available for Windows, Mac, and Linux, the next evolution of our diagnostic scope software is now available.

There are several advantages of having a glow plug tester for your regular usage. We are here to help you choose the best one for your purposes from all the best available products in market today.

Connect the two leads of the multimeter together, making sure the metal clamps/pins on the leads touch each other, and record the result. If you are using a digital multimeter, the precise reading will appear across the screen. At this point you may be able to use your multimeter’s calibration function to adjust the reading to zero. Continued PWM operation for a further 1 min 30 s, to give a total on time of approximately 1 min 45 s. Connect the tester’s plug power lead to the glow plug’s power terminal. The glow plug power terminal is usually a threaded rod at the top of the plug. Analog meters may apply higher voltage to the circuit than the digital meter, so use them with care.

Glow plugs assist ignition by heating up the air and fuel (diesel) mixture. Reaching a high enough temperature allows it to combust under pressure. This can be at over 200° C. Almost all customers found that the glow plug tester is high quality, accurate gauge. They say that the glowplug tester can be used on modern high compression diesel engines. Why We Like This: If the area around the glow plugs has dirt or build-up, clean it first. Some manufacturers offer special tools (“reamers”) to clean out the bore where the glow plugs are inserted into the cylinder head. These tools clean out carbon build-up inside the combustion chamber or pre-charge chamber, as well as the threads that the glow plug screws into. Depending on the system type and engine operating conditions, the glow plugs may be activated for a period of time after the engine has started.

Auto Electrical Parts Natrad can supply and install a range of auto electrical parts for all vehicle types Located on the engine and with a direct connection to the engine control unit, the control module uses a microprocessor to analyse input from the engine control unit to determine information related to the working of the glow plugs. This includes when to switch the current for the glow plugs on and off, and how much current is required as this will differ depending on the starting temperature of the engine. The current to the glow plugs is turned on during the pre-heating to warm up the engine, stand-by time when the engine should be started, and post-heating to meet increasingly strict exhaust gas standards and optimisation of combustion processes. The multimeter should now give a reading. This is when you can adjust the range setting on the multimeter to give more significant figures, if required. DENSO has a history of pioneering innovation in diesel engine components, always making improvements to quality and efficiency. It introduced the first ceramic glow plugs for the OE market, and was behind the first common-rail diesel engine in a production vehicle.
