Connect your digital multimeters positive pin to the positive terminal to obtain the secondary circuit reading. Step 3: Remove any bolts holding down the old part before carefully lifting it out from its mounting location with both hands (or with help if needed). The reading should be between 0-0.5 ohms; if it is higher than this value then the coil needs replacing. Additionally, it may be helpful to refer to the vehicles service manual for specific instructions regarding testing procedures and specifications. Then, disconnect the ignitioncoil wire and secure away from spark plug. Find all Engine Safety Warnings. But if the resistance dramatically exceeds the standard range, then you have to replace the coil too! You are using an out of date browser. Solid-state systems: the more modern option, these systems use a tiny transistor in the coil or armature to close the electrical circuit that travels through the spark plug lead to the spark plug(s), Breaker point systems: used on engines made before 1980, these systems use a mechanical switch instead of a transistor to close the electrical circuit used to produce a spark. If they appear to be in good condition, then move on to checking the spark plugs themselves. Ignition coils are an essential component of any vehicles electrical system. Maybe you are staring at an ignition module problem, spark plug issue, faulty connector or lead, a defective fuel injector, or the cylinder is experiencing mechanical internal engine issues. In summary, while both coils are essential components in any vehicles ignition system, they serve different functions: The primary coil creates an initial low-voltage spark that is then amplified by the secondary coil into a much higher voltage capable of igniting fuel-air mixtures efficiently during engine operation.

Step 5: Reinstall spark plug wires onto their respective terminals on top of the new ignition coil according to the manufacturers specifications found in the service manual/instructions included with the purchase of replacement part(s). If the engine comes with two cylinders, if one coil is damaged, you can replace the one which is damaged. Dont worry if the plug generates a plug. Step 1. You only need to pass a current along the wire and check for resistance using an ohmmeter. I'm planning on replacing the coil with a tecumseh 30560a, but to add a twist, I bought a generic points replacement kit (transisitor ignition module) as my condensor was bad, I thought what the heck. Once the engine is running, the flywheel keeps rotating, the magnets keep passing the coil and the spark plug keep firing based on a specific timing. Coil came with new spark plug wire ? Step 3 Measure the resistance on the circuit you've just created. Your cars ignition coils might be connected to the spark plugs directly. If you do not have repair manual contact your local dealer for the correct specification. Next, attach your multimeter to the high output terminal connecting to the sparkplug. Or you used bad old wire ? If you are using a multimeter, you can set its dial to a 20-K scale. In most older vehicles with a single coil and distributor, the simplest test is often to replace the coil with a known-good or new ignition coil, as well as inspecting the coil for signs of damage or oil buildup, which could indicate that the coil case has been damaged. Well, dont worry! It will help you prevent spark plug damage, besides saving time. Coil boots are made of rubber or silicone and are designed to insulate the voltage to ensure it reaches the spark plug. When working with automotive electrical systems always make sure all power sources have been disconnected before attempting any repairs & always wear protective gear such as gloves & safety glasses while handling any live circuits/wires so as not to get shocked by accidental contact with live current. Another advantage of using a spark plug tester is that your combustion chamber will not be exposed to debris and other risky objects. However, a reasonable range is between 6000 and 10,000ohms. At last, you will have to compare the specifications with your results. While holding the shim, turn the flywheel until the magnets are directly adjacent to the armature, Loosen the tight screw so the magnets pull the ignition armature against the flywheel and shim. One of the things I was wondering was coil gap. I am here to help you with your car questions. Simply removing the wiring connectors and coil wire and loosening or removing the bracket will allow the coil to slide out and the new one to slide back in.
