How does a coil work on a riding lawn mower?
When you start your lawn mower or small engine, you turn the flywheel and its magnets pass the coil (or armature). This creates a spark. Once the engine is running, the flywheel keeps rotating, the magnets keep passing the coil and the spark plug keep firing based on a specific timing.
What are the symptoms of a bad coil on a riding lawn mower?
One of the symptoms of a bad lawn mower ignition coil appears when you are mowing the lawn and the mower gets hot and literally shuts off. The mower must cool down over a period of time and will start and run for awhile until it gets hot again, at which time it will shut off again.
Can you drive with ignition coil?
It is possible to drive with a faulty Coil On Plug (COP), but not advisable. Driving with a faulty waste spark ignition system won’t be possible. Driving with a faulty coil pack can damage other components of the engine. You’ll also learn how to diagnose and replace your faulty coil.
What causes no spark on lawn mower?
Ignition Module Failure When it does fail, it is usually due to heat caused from improper wiring of the ground wire to battery voltage. If the engine does not produce spark, other areas of the ignition system should be checked before focusing on the ignition module as source of failure (see above).
How can you tell if an ignition coil is bad?
If your car is experiencing any of the problems listed below, you may have a faulty ignition coil on your hands:
- Engine misfires.
- Rough idle.
- A decrease in car power, especially in acceleration.
- Poor fuel economy.
- Difficulty starting the engine.
- Check engine light is on.
- Exhaust backfiring.
- Increased hydrocarbon emissions.
How do you check for a bad ignition coil?
Use a spark tester to check the ignition coil.
- Plug the tester into the coil.
- Attach the ground wire.
- Plug in the coil connector.
- Adjust the spark gap to the correct measurement.
- Start the engine.
- If there’s spark, great, it works! If there’s no spark, it’s a bad coil.
How do I fix no spark?
First, Confirm Your Engine Has No Spark:
- Disable the fuel system by removing the fuel pump fuse or relay.
- Insert a spark plug tester into the plug boot and ground it on a piece of metal on the engine.
- Finally, Have someone crank the engine and watch for spark.
What does the ignition coil do on a lawn mower?
The starter coil – more commonly referred to as the ignition coil – in a lawn mower is an essential component because it is responsible for transferring voltage from the battery to the spark plug, which results in the spark that starts the mower.
How do you test a lawn mower ignition coil?
Plug the free end of the tester into the original spark plug boot. Push it in firmly to make sure there is a solid connection. Start the mower when it is cold, and look through the window of the tester. Observe that there is a normal spark that allows the mower to run.
Where is the solenoid on your Craftsman riding mower?
Look along the mower’s frame or back of the engine compartment to locate the solenoid. On most models, the solenoid is a cylindrical or square palm-sized black device bolted to the mower frame near the engine or bolted on at the back of the engine compartment near the battery.
How does a lawn mower ignition coil work?
Lawn mowers with magnetic coils have a capacitor discharge, a type of electronic ignition that consists of a magnetic flywheel and stator coil. When the magnetic flywheel passes the ignition coil, the magnets trigger the coil to produce a charge that is sent to the spark plug at just the right time,…
