OTC 3673 Diesel Glow Plug Tester

Product Information

Disconnect the power cable from the glow plugs. If you don’t do this, your tester will be powering all the glow plugs instead of just one. Doing this will give you bad results, and may damage the tester. Glow plug relays are a crucial part of the ignition system in most diesel vehicles. The glow plug control unit assesses input from the ECU when you turn the key in the ignition. It determines the currents and timings needed by the plugs to start the vehicle.

What’s more, they’ll allow you to test the glow plugs themselves without having to remove them from the engine making it a much easier process all round. Quality Glow Plug Testers Remove the connecter or cap fastened to the glow plug. This is where the pliers might come in handy, but be careful to not break the wiring. 4. Remove glow plug We looked at 5 other Glow Plug Testers. Even though they didn’t make our 5 best Glow Plug Testers list, they’re the best of the best and each is still a great option. The information you’ll need to compare each one is included with the listing. The reading on your digital multimeter must be at least 1 ohm for a good glow plug. Keep in mind that the actual reading might differ based on your engine’s temperature, the quality of the earth connection, the accuracy of the multimeter, and other factors.There are three main signs that show you that you need to test, and possibly replace, your glow plugs:

If all of the glow plugs read within the acceptable range determined by the owner’s manual, there is another reason for issues with your car. However, if one or more reads abnormally high, this may be affecting engine performance. It might be time to replace one or more of the plugs. Replacing your glow plugs utiliser avec le kit de test de compression diesel 4510 et le kit de test de fuite de cylindre 5140. Almost all customers agree that the glow plug tester is easy to use and good value. In addition, a few say that the glow plug tester works well and at a reasonable price. While the multimeter can seem daunting because of its many numbers and dials, you only need to use one setting for this test: Ohms. The ohms setting will be denoted by the omega symbol (Ω) resembling a horseshoe. Unless you have an auto-ranging multimeter, you will also be able to set the maximum range for the test. You can always change this during the test if you find you aren’t getting a useful reading,Rapid glow plugs have two coils internally connected in series, a small heating coil at the plug tip and a larger regulating coil within the plug case. These systems use Pulse Width Modulation (PWM) of the supply voltage to regulate the circuit current and to control glow plug temperature.

It is best to use a digital multimeter for this test. A digital multimeter shows the exact number result of the test. An analog multimeter is harder to read because every possible result is listed at the top. [4] X Research source The first reading you get from a digital multimeter may not be accurate, since the current can fluctuate. Digital multimeters have a difficult time measuring current that is constantly changing. [3] X Research source Because analog multimeters have a changing display, they can show you the current fluctuations. However, analog multimeters are less accurate overall. The glow plug control module determines the timing and electric current required by the glow plugs based on input from the Engine Control Unit; Designed specifically to work with Laser 4510 diesel compression tester kit and Laser 5140 cylinder leakage tester kits. The 7239 diesel compression test glow plug adaptor is designed to replace the cylinder glow plug, allowing connection to compression and leakage test equipment. To test the function of your glow plug, you’ll need to start with your multimeter. This digital device measures electrical circuits. Using your multimeter.Do you have a diesel car? Then you might be familiar with glow plugs, which are used to create ignition in diesel vehicles. They are the equivalent of spark plugs in a petrol car but work slightly differently to start the engine. Join our Team Join Australia’s most recognised and trusted radiator and air conditioning specialist The heating element in the glow plug is electrified so it heats up and emits visible light (hence the name); To test your glow plugs, simply connect a 12-volt test light to the positive battery terminal. Then disconnect the wires from each of your glow plugs and touch the probe of the test light to the terminal of the glow plug itself (not the wiring harness). If the light doesn’t light up, the glow plug is bad and should be replaced. Observe the result on the glow plug tester display or gauge. Most testers will have a ‘good’ range, and some will display the current. If a value is displayed, you should record it, for comparison with the other plugs.

Almost all buyers found that the glow plug tester is designed for outdoor use at any temperature. A few say that the glow plug tester is compatible with many different types of vehicle batteries. Why We Like This:BERU offers a range of innovative glow plugs, each with specific features for a variety of applications. Clip the multimeter’s negative lead to a ground point in the engine. The main two ground points can be found by following the wire that leads from the negative battery terminal into the engine wall or following the wire that leads from the alternator into the engine wall. These wires are attached to bolts. Attach the negative lead onto one of these bolts for grounding. 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.
