Disconnect the distributor cap end of the coil wire and attach to an ignition tester. Attach the ignition tester to a good ground, away from any fuel lines. A good spark tester can be made from an old spark plug gapped to 0.200". Crank the engine and observe the tester for spark. If a crisp blue spark is noticed, the ignition coil is working properly. If a pale yellow spark, or no spark, is noticed, the coil is more than likely bad.
A 1995 Geo Metro ignition coil is tested by measuring the resistance across the coil. If it exceeds the manufacturer's recommendation, it must be replaced.
You can test the ignition coil on a car by using a multimeter. A bad ignition coil can be the cause of a car not starting.
1999 Alero how do i test ignition coil pack
Coil? HEI ignition system?
You cannot test it with a diagram. You will need a multimeter to test the coil. Click the link.
test ignition coil,ignition module,pick-up coil,electronic spark control,and knock sensor
You test an ignition coil by checking the resistance with an ohm meter. The resistance values should be something like, Primary winding .3 to 1 ohms, Secondary winding 8,000 to 11,500 ohms.
let the engine running, lift off the ignition coil one by one after opening the screw...a tick sounds will be heard ... no tick sound and gasoline leak on the plug thread means the ignition coil is busted.
If you are not getting spark to any of the plugs could be coil rotor and/or cap HEI ignition?
Try the ignition control module. Had the same problem with mine $36 part fixed it. The ignition control module is in the distributor and so is the pickup coil, but the ignition coil is by the battery. There is a spark test that can be done. If it was already done and couldn't see a spark, then it could be the ignition coil it self , the ignition wire, or any possible electrical connections.
Use an ohmeter to test tesistance where the plug wires connect to the coil-it should read 12,000. now for the the primaray side where the signal wires connect to the coil should be 2-3 ohms.
Many autopart stores have a machine to test it. The machines use a universal adapter to hook into the ignition control module. The ignition control module is in the distributor. If you mean the part that contains the ignition coil, when mine went bad I probed it with an ohmeter and then asked the parts store if I could test the resistances in a new coil before I bought it. Since the resistances of certain terminals weren't even close, I knew I had a bad coil.
Test the wiring between the computer and the coil.
test for power before the coil, if you have power change the coil, if not trace the wires back and check for broken parts or bad connections.
If you have an Ohm meter you will want to measure the resistance (ohms) of the Primary and Secondary sides of the coil pack and compare your readings to the Specifications for the vehicle.
There is no ignition module in a '84 laser. They have a coil and distributor unless it has been modified. If you don't get a spark across the points in the distributor when you try to start the engine you probably need a new coil.
Remove it and test it. A good service manual for your car should tell you what to look for. If you don't have an ohm meter to test it, remove the coil and take it to a reputable auto parts retailer in your area.
first check your spark plug then test your ignition coil if these are good then it is probably the cdi but there is no way to test a cdi box.
First, see if the each coil is getting the required voltage from the ignition switch (probably 12V). If they are, you can check the resistance of the coil with a simple volt meter. Should read minimal resistance. If the meter reads OL then the coil windings are open (defective/bad).
If there is no spark either the coil or ignition module has probably failed. These components are part of the distributor assembly and are not sold separately.
hey are located inside the distributor and function as the trigger for the ignition system to produce spark. The pickup coil monitors the rotation
check your distributor ignition module and go test it...
