Most if not all small 2 cycle engines today use a similar ignition system setup. Step 3: Test the secondary coil resistance. All you will need is a multimeter. Why? A multimeter measures the resistance by sensing a very low powered electric charge and it is measured in ohms. In this video I will show you how to test the ignition coil on a chainsaw without any special tools.Step by Step . Here, even if there is only slight damage to your coil, your readings will indicate such. This article will shed some light on the 'working theory' and the testing of the Coil-On-Plug type with two wires (circuits) in its connector (the article dealing with the three wire (circuit) Coil-On-Plug type can be found here: Testing and Troubleshooting 3 Wire COP Ignition Coils). To test the resistance of the coil in your chainsaw which is called a bench test, take your multimeter and remove the coil from your chainsaw to get easy access to its electrical terminals. You can test a 12-volt ignition coil for effectiveness by checking the resistance of its wire windings with a multimeter. To ensure our content is always up-to-date with current information, best practices, and professional advice, articles are routinely reviewed by industry experts with years of hands-on experience. For a simple understandable description, the module itself contains two coils of wire. How to Check Engine RPMs with an Analog ... How to Check Engine RPMs with an Analog Multimeter. After removing the spark plug, reattach the plug wire. Testing a Spark Plug Ignition Coil in 7 Steps. You can check the resistance with a multi meter that allows you to test ohms or a dedicate ohms meter. You can find the test steps here: TEST 4: Spark Test At Ignition Coil Tower (this test belong to this tutorial: How To Test A Misfire / No Spark-No Start Condition (4.3L, 5.0L, 5.7L 96-04)). Set the meter to 20K Ohm setting, and attach the leads to the ignition coil's center terminal. If you're conducting the bench test, refer to your service manual and remove the coil to take it to bench. Though the coil produces electricity, testing it involves resistance of the coil windings. As with most types of vehicular maintenance, you'll want to begin the test with the vehicle in park and with the engine off. submitted to our "DoItYourself.com Community Forums". Testing the resistance across several terminals on your ignition coil is the only safe and accurate way to tell if the coils is damaged or not. While ignition coils are generally very sturdy and reliable, over time, due to heat, vibrations, and faulty insulation, they can become damaged. Step 2 - Open the Coil Housing. Place the Stihl tool on a sturdy work surface. Measure secondary resistance. In this step-by-step guide, we will go over how to test if an ignition coil is good or bad, by testing the resistance using a digital multimeter. When the key is turned on, you … Most if not all small 2 cycle engines today use a similar ignition system setup. The ignition system has two wires attached to the switch’s run terminal. 1973 Cadillac (472 Engine) Ignition Problems. The testing of these two circuits is done in part while the engine is being cranked. I bought mine for $25 and it works great. This part is essentially an induction coil and, simply put, a high voltage transformer. Testing these circuits can be accomplished in several different ways. On one end of each coil both are grounded together to the laminate frame that attaches it to the engine block. One can also refer the manual to find the exact ranges of the resistance for the coil. Find out what the correct resistance reading of the ignition coils should be for your vehicle. In the first, you are relying on the spark to determine the condition of your coil; in fact, only in a no-spark condition would you be certain that your coil is faulty. NOAA Hurricane Forecast Maps Are Often Misinterpreted — Here's How to Read Them. Testing Ignition Coils. Mandatory government vehicle testing - lowered car. You could even use the car's engine for this. Disconnect the small grounding wire, attached to the side of the coil, with a wrench. For one, there are many different methods for testing them, some low-tech and others high-tech, and we will cover them all. Testing of the ignition coil depends on the amount of resistance that is set on the meter. Make sure that the engine of your chainsaw is turned off and it had a chance to cool down before you perform the bench test. An ignition coil is a kind of high-voltage transformer. Watch for a spark in the tester window as you pull the starter cord. To test the resistance of the coil in your chainsaw which is called a bench test, take your multimeter and remove the coil from your chainsaw to get easy access to its electrical terminals. Ignition coils are usually very simple to remove, often times only held in by one or two bolts. Refer to your service manual for the correct resistance readings applicable to your vehicle and model.

If the ignition coil on your chainsaw fails, it will prevent the saw from starting because it does not allow the spark plug to operate. Testing or checking an ignition coil can tell you a lot about the health of your ignition system. The normal, acceptable range for a standard 12-volt car is 1.5 to 1.7 Ohms. Using an ohmmeter, check the resistance between the side terminals of the coil. The terminals of the coil are going to be marked "negative" and "positive," and these are the two points where the resistance of primary winding can be measured. Step 2 Attach an automotive coil tester by placing the end of the tool with grooves over the sparkplug wire. Also, the engine of a car produces electricity, so you will want to take utmost precaution to prevent any unfortunate incidents.
