When testing your string trimmer with the system tester, you'll need to watch for a spark in the test window. If a weak spark appears in the window, this means you'll need to replace the ignition coil. If you see a strong spark but the string trimmer still fails to start, you can ...
How do I test a spark plug with a multimeter? Connect your multimeter to the positive terminal or pin of yourcoil, and to the high output terminal that goes to the spark plug. Most ignition coils should have a secondary resistance falling somewhere between 6,000 to 10,000 ohms;however, ...
For this reason, a plug sparking in this way does not guarantee that it will be functional during normal running operation. Watch this video to learn how to test your spark plugs in just one minute: Don’t Miss These Things during a Spark Plug Diagnosis! You already know how to check ...

BYLINE: Ken CorkettI GET a lot of queries about very basic engine tests; last week a Mr S Norman asked me to explain the difference between a compression test and a cylinder leakage test.The answer is that they both give you a pretty good idea about the sealing properties in the ...
circuit. When current flows in the primary circuit, energy builds within the coil’s magnetic field. If the current is quickly removed, the magnetic field rapidly collapses and induces a high voltage in the secondary coil. The high voltage is delivered to a spark plug via a secondary circuit...
Perform a spark test. Disconnect the wire from the spark plug and insert a metal screw- driver into the boot of the spark plug, which is the area that holds the spark plug. Holding the plastic handle of the screwdriver, bring the metal area of the screwdriver close to a metal part of...

The electronic ignition control module is a solid state "On/Off" switch for the ignition system. The module receives a signal from a sensor inside the distributor. The signal is then used to fire the ignition coil creating the energy for the spark plugs.
