Remove the kill wire from the ignition coil. It's the only wire that doesn't go to a plug. Remove one of the spark plugs. Reconnect the plug wire to the plug that has been removed. Make sure the threads of the plug are touching metal on the engine somewhere. Crank the engine. Should see spark.
If not, bad coil.
To troubleshoot a faulty lawn mower ignition coil, first check for loose or damaged connections. Next, test the coil with a multimeter to see if it is producing the correct amount of electrical resistance. If the coil is not functioning properly, it may need to be replaced.
To test a lawn mower coil, you can use a multimeter to check the resistance between the coil's terminals. If the resistance falls within the manufacturer's specified range, the coil is likely functioning properly.
what are you trying to measure and with what type of meter? generally we check the module with a spark tester. if there is no spark with the spark tester we check the kill wires and any safety switches that may cause a no spark issue and if all that still shows no spark then we replace the module.
check with meter to see resistance value (ohms)should read 3.4

To test a mower ignition coil, first, ensure the mower is off and disconnected from the power source. Use a multimeter to check the resistance across the primary and secondary terminals of the coil; typically, primary resistance should be between 0.5 to 2 ohms, while secondary resistance should range from 5,000 to 15,000 ohms. If the readings fall outside these ranges, the coil may be faulty. Additionally, you can perform a spark test by removing the spark plug, grounding it, and pulling the starter to see if a spark is produced.
with a kohler regulator tester
I have a similar problem with a kawasaki mower. it was running fine, emptied the catcher and wouldn't restart. Found plug fouled, no start with a new plug. removed coil, and with an ohm meter tested continuity of poles to each other, inconclusive. found a good coil from a different B&S mower and compared readings. Kawasaki had continuity with plug lead and center pole on pick-up, B&S did not. I assume the center pole is grounding out the plug lead, so I will replace the coil and see.
You cannot test it with a diagram. You will need a multimeter to test the coil. Click the link.
