How close should the ignition coil be to the flywheel?
010-inches or between . 010 and . 014-inches. Rotate the flywheel so that the flywheel magnets line up directly with the magnetic coil and filler gauge tool.
What happens if the gap between the magnet and Magneto is too small?
In the diagram on the right, we can see a magneto ignition coil and a flywheel. The air gap between the coil and the magnet on the flywheel is vital if we are to produce a good quality HT spark. If the air gap is too small, the flywheel can physically contact and damage the laminated iron core of the ignition coil.
How do you know 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.
When do you Know Your ignition coil is working?
If your ignition coil is working properly, when your friend cranks the engine, you should see a bright blue spark jump across the spark plug gap. This spark will be clearly visible in the daylight. If you don’t see a blue spark, your ignition coil is probably malfunctioning and needs replacement. Orange sparks are a bad sign.
How do you fix a bad ignition coil?
Remove the spark plug, preferably by using a spark plug socket. Clean it using a soft cloth, especially if there are carbon deposits. Attach the wire back to the spark plug. Keep the threaded portion of the spark plug very close to a metal part. Note that you should not hold the spark plug in hand.
How do you test a Harley ignition coil?
Things you will need to perform the test – SAE wrench set and an Ohmmeter. Turn off your bike and wait until the engine becomes cool enough to touch. With your hands, disconnect the plug wires off the coil. You need to use an SAE wrench to unscrew the small connections.
How do you reattach a spark plug to an ignition coil?
Attach the spark plug back to the spark plug wire. Now, carefully reattach the spark plug to its wire. You should be left with a spark plug that’s connected to the distributor but not seated in its “hole.” Handle the spark plug with insulated pliers to avoid the possibility of electric shock.

How do you remove the ignition coil from a car?
Remove the spark plug wire from the spark plug. Loosen the mounting bolts that hold the ignition coil to the engine frame. This will usually mean unscrewing small bolts or screws, or sometimes a pair of set screws. Remove the ignition coil from the bracket or mounting block holding it in place.
How do you test an ignition coil on a lawn mower?
If the ignition coil has a ground wire, also loosen and remove this at the point it attaches to the lawnmower chassis. Touch the red lead on the ohm meter to the spark plug connection and touch the black lead to the armature on the ignition coil. Lay the ignition coil on a work surface. Set the dial on an ohm meter or multi-meter to 20k ohms.
How do you test an ignition coil with an ohm meter?
Set the dial on an ohm meter or multi-meter to 20k ohms. Insert the positive lead on the ohm meter into the end socket or the metal hoop on the spark plug wire. Put the negative lead of the tester onto the metal armature portion of the ignition coil.
