simple to use and can be bought online or at your local hardware store. To test your string trimmer's ignition coil, connect the tester between the spark plug boot and the engine.
It eliminates the need for spark plug wires and improves performance, efficiency and durability. This advanced system is now standard on most modern vehicles for its superior reliability and energy efficiency. Coil-on-Plug (COP). Source: hummelink-modifications.nl How to test the ignition coil...
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, ...
Step 1 Clip the spark tester to a clean metal part of the engine. Disconnect the spark plug wire from the spark plug, and attach the wire to the spark tester. Attempt to start the engine, and watch the spark plug tester. If you do not see a spark as the engine spins, proceed to ...
The ignition coil serves as a high voltage transformer. It steps up the ignition system's primary voltage from 12 volts up to thousands of volts. The actual firing voltage needed to create a spark across a spark plug's electrode gap depends on the width of the gap, the electrical resistanc...
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...

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. The ignition module may be located ...
