How To Bench Test Ignition Coil Manual - If you are performing the bench test, refer to the service manual and remove the two windings (primary and secondary) that are inside your ignition coil. 3. Inspect for sparks (spark plug test). How to Test a Stihl Ignition Coil How to Test a Stihl Ignition Coil. Stihl makes several types of equipment that withstand high usage for professionals or homeowners who require extra power, dependability and longevity of their power tools.. Current ramp ignition components without the need of a current clamp or an oscilloscope. When a vehicle is not running or you want to bench test a component an oscilloscope is unable to be used for testing unless you can "run" the component. The EDEA tester is able to run your components and at the same time read, record and playback the amperage waveform for analysis..
The Ignition Coil is the unit that generates the sparks to be sent to the plugs. They are quite robust units and rarely cause trouble, but if consistent rough running presents itself, and all other diagnostic tests have revealed nothing, the coil should be suspect. The following test will determine whether or not it is working correctly.. How to test an ignition coil This testing procedure is valid for just about any automotive coil. Using an ohmmeter, check the resistance between the side terminals of the coil. Using an ohmmeter, check the resistance between the side terminals of the coil.. The ignition will likely work with any capacitance value between 0.05 and 0.6 microfarad. Too high or too low value may eventually transfer metal from one side of the contact points to the other side leaving a pit and a point. Capacity of spark coil capacitors ranges from 0.2 microfarad to 0.33 microfarad. Almost all automotive coils use a 0.25-0.29 microfarad capacitor..
18.01.2009 · This testing procedure is valid for most automotive coils. Using an ohmmeter, check the resistance between the side terminals of the coil. Do this with all of the wires to the coil disconnected.. At this point, conduct the spark test one more time; if no spark appears, you need a new coil. If you remove the coil and a spark appears, there is a wiring issue with the ignition coil. If you remove the coil and a spark appears, there is a wiring issue with the ignition coil.. Bench test is not the way to go, the on the engine test is the best. You unplug the kill wire and if you do not have spark, the coil is bad. You unplug the kill wire and if you do not have spark, the coil.
A digital multimeter is required for testing the resistance levels of the ignition 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..
