How to Test Kohler Ignition Coil
An ignition coil is a crucial component in the ignition system of an engine, responsible for converting low-voltage electricity from the battery into high-voltage electricity required to spark the fuel-air mixture. Kohler ignition coils are known for their durability and reliability, but like any mechanical component, they can fail over time. Testing a Kohler ignition coil is essential to ensure your engine’s performance and prevent potential breakdowns. In this article, we will guide you through the process of testing a Kohler ignition coil, helping you determine if it needs replacement or repair.
Materials Needed:
Before you begin testing the Kohler ignition coil, gather the following materials:
1. Multimeter: A digital multimeter is essential for measuring voltage and resistance.
2. Ignition coil socket: This tool is designed to safely connect to the ignition coil for testing purposes.
3. Socket set: A set of sockets will be needed to remove the ignition coil from the engine.
4. Replacement coil (if necessary): Have a spare ignition coil on hand in case the test reveals a faulty one.
Testing Procedure:
1. Disconnect the battery: Before starting the testing process, disconnect the battery to avoid any electrical shocks or damage to the multimeter.
2. Remove the ignition coil: Use the socket set to remove the ignition coil from the engine. Be sure to disconnect any wires or connectors connected to the coil.
3. Connect the multimeter: Attach the multimeter leads to the appropriate terminals on the ignition coil. Typically, the primary side of the coil is connected to the engine’s ground, while the secondary side is connected to the spark plug.
4. Test the primary winding resistance: Set the multimeter to the ohms (Ω) setting and measure the resistance between the primary terminals. A healthy Kohler ignition coil should have a resistance between 0.5 and 1.5 ohms. If the resistance is outside this range, the coil may be faulty.
5. Test the secondary winding resistance: Set the multimeter to the kilo-ohms (kΩ) setting and measure the resistance between the secondary terminals. A healthy Kohler ignition coil should have a resistance between 8,000 and 12,000 ohms. If the resistance is outside this range, the coil may be faulty.
6. Test the coil’s output voltage: Connect the ignition coil to the engine and reconnect the battery. Set the multimeter to the voltage (V) setting and touch the probes to the spark plug’s terminal. Crank the engine and observe the voltage reading. A healthy Kohler ignition coil should produce a voltage between 12,000 and 20,000 volts. If the voltage is below this range, the coil may be faulty.
7. Inspect the coil’s physical condition: Check the coil for any signs of damage, such as cracks, corrosion, or loose connections. A damaged coil may not function properly and should be replaced.
8. Reinstall the coil: If the coil passes all the tests, reinstall it into the engine. If the coil fails any of the tests, replace it with a new or rebuilt coil.
By following these steps, you can effectively test a Kohler ignition coil and determine its condition. Regular testing and maintenance of your ignition system will help ensure the smooth operation of your engine and prevent costly repairs.
