No spark on your Briggs & Stratton? Check the air gap between the magnetic coil and the flywheel, replace the ignition coil, and test the spark with a multimeter. If none of these steps solves the problem, you may have a defective ignition module. If the ignition module is the cause of no spark, your next step should be to contact a Briggs & Stratton dealer and get it replaced.
6.5 HP Briggs and Stratton engine won’t start
If your 6.5 HP Briggs and Strattoon engine won’t start in the rain, it may be because the fuel mixture is too rich. Check your engine’s manual and contact Briggs & Stratton for assistance. You might have a sheared key on the flywheel, a vapor lock, or a damaged magnet.
You can diagnose a hard-to-start Briggs & Stratton engine by checking the voltage at each battery terminal. The voltage should be 12 volts. If it isn’t, you may need to replace the battery or replace it. If the problem persists, contact a repair shop. Alternatively, you can perform a self-test with a voltmeter.
If your 6.5 HP Briggs and Stratston engine won’t start, you can check the ignition system. The spark plug is located on the right side of the engine. The ignition wire is thin and black. To inspect the ignition system, use a socket wrench. If the ignition wire is loose or not tight, contact a repair shop for help. If you can’t find the problem, a shop representative will be glad to assist you.
Checking the air gap between the magnetic coil and the flywheel
Before you start your engine and begin to diagnose the problem, you need to make sure that your air gap is in the correct range. The proper gap should be between 0.010 and 0.015 inches wide. Unless this gap is 0.020 inches or less, it is most likely too wide or too small. To check if this gap is right for your engine, turn the engine to the start position. If you don’t hear any spark, you may need to replace the magnetic coil.
The gap between the magnetic coil and the flywheel is a critical component. If it is too large, it can affect the flow of magnetic flux. To measure this gap, place a standard business card in between the E core and flywheel magnets. If the gap is too large, corrosion or oil can prevent the magnetic flux from reaching the HV coil. To remove these problems, sand and tighten the screw to the proper thickness.
Another cause of Briggs and Stratton no spark is a faulty electronic switch. The electronic switch in your engine is probably the cause of this problem. It is possible that you have a bad or outdated ignition switch, or you could just have a faulty ignition switch. If you follow these steps and find that the spark does not appear, the ign switch is most likely the problem.
You can also check the spark plugs. If they are dirty, cracked, or missing insulation, they are most likely the cause of no spark. A good method of testing a spark plug is to use a spare plug. However, it’s crucial to avoid using plugs from another vehicle because these plugs could damage the pistons.
The secondary coil should also be checked. Use a digital multimeter to measure the resistance of this component. It should be between 2.5 and five kiloohms. If this value is outside of these limits, you should replace the coil. Checking the air gap between the magnetic coil and the flywheel is the next step in troubleshooting a Briggs and stratton no spark problem.
Replacing the ignition coil
One of the first steps in Briggs and Stratton no spark troubleshooting is to check the ignition coil. There are two different types of Briggs and Stratton coils, which are easy to spot. You can also look for magnet marks on the flywheel to determine whether the coil is bad. After checking the ignition coil, insert the filler gauge and rotate the flywheel to make sure that the space between the flywheel and coil is aligned.
If the ignition coil is not getting power, you can clean it with sandpaper or files. If it does not produce spark, you can try replacing the ignition coil. Before doing this, check the engine’s stop switch for proper operation. If it works properly, plug the spark plug lead into the coil. Once the ignition is working, try starting the engine. Checking the ignition coil is a simple process, and will resolve most no spark issues in older Briggs and Stratton engines.
After checking the other suggestions, you should replace the ignition coil. If the spark returns after replacing the ignition coil, you will need to check the distributor and wiring. If the spark is restored after replacing the ignition coil, the problem may have been caused by a damaged spark plug or the ignition control module. Replacing the ignition coil is a simple fix for no spark, and it is the easiest step in troubleshooting your Briggs and stratton no spark problem.
Once you’ve checked the wiring and connectors, you can move on to the other components of the ignition system. A loose connector or faulty wiring could disrupt the circuit. Also, make sure the grounds are solid, as corrosion could lead to an inconsistent spark. Using the proper tools is vital when troubleshooting a no spark situation, so be sure to follow manufacturer’s instructions carefully.
You can find replacement coils for Briggs and Stratton engines ranging from two-half HP to sixteen-horsepower. Make sure that they have a two-legged core and are at least 0.1-inch larger than the old coil. You can find replacements in scrap yards for trashed push mowers. Just make sure to measure the dimensions carefully.
Testing the ignition coil with a multimeter
To test the ignition coil for Briggs and stratton no-spark problems, you must know how to connect the spark plug and kill wire. To do so, you should use a multimeter. Place the end of the multimeter’s probe on the kill wire terminal and the spark plug’s base. If the multimeter’s resistance reading falls outside of a certain range, the ignition coil is faulty.
Another way to test the ignition coil is to use an old spark plug and put it on a metal surface. Then crank the engine, and you should see a spark. If you do not see a spark, then the ignition coil is the problem. Next, you must connect the multimeter’s leads to the positive and negative terminals of the battery. If the multimeter shows a reading of ten thousand ohms or more, you need to replace the ignition coil.
The wiring and connectors should be inspected thoroughly. Check for corrosion and faulty connections. If any of them are loose, it may disrupt the circuit. Make sure both male and female wiring terminals are solid. You should also check the ground connections to make sure they are secure and grounded. Check the ground wire with a multimeter to confirm the ignition coil is the cause of Briggs and stratton no spark troubleshooting.
You can also check the ignition coil with a multimeter by removing the cardbord and turning the magneto. Once you’ve checked all these suggestions, you can replace the coil and see if it solves the no-spark problem. The last step to troubleshoot Briggs and stratton no spark is to check the ignition coil with a multimeter.
Before you can perform an ignition coil test, you should check the resistance of the ignition coil with a multimeter. You need to connect the positive and negative terminals to the multimeter. If the readings are within the limits, the ignition coil is probably the culprit. Inspect the ignition coil to check if the spark plug is actually igniting or not.
