Understanding the Ignition Coil
What is an Ignition Coil?
The ignition coil is a vital component in your Craftsman lawn mower’s ignition system. Its primary function is to transform low-voltage battery power into high-voltage electricity, which is necessary to ignite the fuel in the engine. Without a functioning ignition coil, your mower won’t start, making it essential to understand its operation and maintenance.
Signs of a Failing Ignition Coil
Recognizing the symptoms of a failing ignition coil can save you time and money. Common signs include:
- Difficulty starting the mower
- Intermittent engine performance
- Poor fuel efficiency
- Engine stalling during operation
- Backfiring or misfiring noises
If you notice any of these issues, it’s time to investigate the ignition coil.
How to Test an Ignition Coil
Tools Needed
Before testing your ignition coil, gather the following tools:
- Multimeter
- Screwdriver set
- Insulated gloves
Testing Steps
- Safety First: Ensure the mower is off and disconnect the spark plug wire.
- Access the Coil: Remove the engine cover to access the ignition coil.
- Check Resistance: Use the multimeter to measure the resistance across the coil terminals. Refer to your mower’s manual for the appropriate resistance values.
- Inspect for Damage: Look for any signs of wear or corrosion, which can indicate a faulty coil.
- Reassemble: If the coil passes the test, reassemble your mower. If not, it may need to be replaced.
How to Replace an Ignition Coil
Step-by-Step Guide
Replacing an ignition coil might seem daunting, but following these steps can simplify the process.
- Gather Tools: You’ll need a wrench set, multimeter, and new ignition coil.
- Safety Precautions: Ensure the mower is off and remove the spark plug wire.
- Remove the Old Coil: Unscrew the ignition coil from its position, taking care to note the wiring connections.
- Install the New Coil: Position the new ignition coil and secure it with screws. Reconnect any wires.
- Final Checks: Replace the spark plug wire and reattach any covers.
Tips for Successful Replacement
- Always refer to your mower’s manual for specific instructions related to your model.
- Double-check all connections to ensure they are secure.
