Learn how to test a Briggs and Stratton ignition coil to determine whether or not it needs replacing.
Set the multimeter to the 20 k ohms setting. A working ignition coil will give a reading of between 2.5 – 5 k ohms.
Set the positive lead of the multimeter in position where the spark plug would usually insert – ensure it has made good contact. Place the negative lead onto the metal body of the ignition coil – again ensuring it makes proper contact.
Look for the reading on the multimeter. A reading of 2.5-5.0 kohms indicates the ignition coil is in working order. No reading indicates a broken circuit, a higher reading will cause either a weak or non exsistant spark.
