Troubleshooting a Briggs and Stratton magneto is not as difficult as you might think. You simply need to follow the steps in this article. First of all, you should check the air gap between the magnetic coil and the flywheel. Then, you should check the connections between the coil unit and the engine block, spark plug, and coil. If none of these troubleshooting steps work, you should contact your manufacturer or dealer.
Checking the air gap between the magnetic coil and the flywheel
To check the air gap between the magnetic coil and the engine flywheel, remove the spark plug and oil filler tube, then unscrew the oil-filler tube bolt. Using a non-magnetic feeler gauge tool, position the gauge between the coil and flywheel. The magnets on the flywheel are attracted to the coil, and the tool must rotate to dislodge them.
The primary coil should have a resistance of one ohm, and the secondary coil should have a resistance of about.020. To check the resistance, connect a meter probe to the spark lead. If the resistance reading is greater than one ohm, the coil has a fault.
A faulty magneto can lead to an engine being unable to start. To troubleshoot a Briggs and Stratton engine, check the air gap between the magnetic coil and the flywheel. If the air gap is too small, you need to replace the magneto or the engine. If the spark plug is not firing, you can fix the ignition coil or the flywheel.
If the problem persists, adjust the air gap between the magnetic coil and the engine flywheel. Usually, this is the first step in diagnosing the problem. The air gap between the magnetic coil and the flywheel can cause the magneto to malfunction, so adjust the gap accordingly. Then, reattach the ignition armature.
Checking the connection between the chassis of the coil unit and the engine block
The connection between the chassis of the magneto coil-unit and the engine block should be clean and free of debris. The magneto coil should not be grounded inside, and should be bended over the armature. The ignition switch should be disconnected from the car while checking the magneto coil resistance. Checking the connection between the chassis of the magneto coil unit and the engine block can reveal a problem with the points. If the points are not working properly, you may need to replace the coil.
If the spark plug is not connected, check the wiring by connecting the meter probes to the ends of the ignition coil. The primary coil should be grounded, while the secondary coil should be connected to the spark lead. If the meter reads higher than 2.5 kiloohms, check for any loose connections. If the meter reads lower than that, you need to replace the coil.
Checking the spark plug
If you are having trouble starting your Briggs and Stratton engine, you may be wondering how to check the spark plug on this engine. If you’ve got this problem, you’ll need to remove the spark plug and clean it. Here are some tips that will help you check the spark plug and know when it needs to be replaced. – If the spark plug has a gap, make sure it’s not too tight.
– Make sure the spark plug is grounded properly. If there is no spark, the coil chip is faulty. To test it, disconnect the kill wire and pull the spark plug. It will fire properly if it fires when it is in the air. But, if you don’t get a spark, it’s possible that the coil is not strong enough to fire the spark plug under full compression.
– If the spark plug is not sparking, try to pull the engine out by a rope and disconnect the ignition. Once you have removed the spark plug, place the new one in the engine compartment. Be sure to route the spark plug wire in the same way as you removed the old one. After this, tighten the magneto screws. If the gap is too large, you should replace the spark plug. If this doesn’t solve the problem, you may need to replace the ignition coil.
Before you start checking the spark plug on a Briggs & Stratton magneto, make sure the engine is off. This prevents electrical shocks, which can be very unpleasant. If the spark plug doesn’t appear in the tester, then you’ll need to replace the ignition module. Fortunately, Briggs & Stratton engines use the 802574 model of magneto.
Checking the coil
Checking the coil is an important part of briggs and stratton magnetometer troubleshooting. A Briggs & Stratton magneto’s ignition coil should have an ohm value of between two and nine ohms. If you can’t see a reading between these values, then the ignition coil is probably faulty. The best way to determine if the coil is damaged or shorted is to check the resistance between the two pieces of metal with a multimeter.
To check the coil, you can rotate the flywheel and line up the space with the magnet marks on the flywheel. You can also insert a filler gauge and make sure it’s the proper distance. You should consult your Briggs and Stratton user manual to determine the proper distance between the coil and the flywheel. Afterward, you’ll know whether the coil is damaged or not.
Checking the coil is the first step in magneto troubleshooting. The magneto has exposed copper windings that connect to the spark plug. You’ll need a multimeter with an ohms function, which is on the higher end of the scale. An ohmmeter with an ohms range of 40 k is ideal, as auto ranging with magnetos is unreliable. The readings you see should be between three and fifteen k, a reading higher than this is a sign of a poor connection.
To test the ignition coil, first disconnect the flywheel brake and remove the ignition coil. If no spark is seen on the tester, then you must check the wires to find the problem. If you cannot find the problem, you should contact a Briggs & Stratton dealer to replace the ignition module. It’s an electronic module and usually fails due to heat generated by the wiring system.
Checking the stop switch
If your 16 horsepower Briggs and Stratton engine won’t fire, it’s likely that your ignition armature coil is not working correctly. Most ignition armature coils are beyond repair, but if you’re not able to get it started, it’s possible that the air gap between the flywheel and coil is incorrect. Another cause of low spark may be a buildup of dirt and debris on the flywheel magnets or a rusty ignition armature coil leg. In such cases, cleaning the ignition components should fix the problem.
