A working ignition coil will give a reading of between 2.5 – 5 k ohms. Set the positive lead of the multi-meter in position where the spark plug would usually insert – ensure it has made good contact.

How many ohms should a Briggs Stratton coil have?

A working ignition coil will give a reading of between 2.5 – 5 k ohms. Set the positive lead of the multi-meter in position where the spark plug would usually insert – ensure it has made good contact.

How do I test a magneto coil with a multimeter?

Pull the rubber casing off the spark plug. Set the multimeter into the ohms function, or just use an ohmmeter. Manually set the dial or button on the meter to the 40 k range. Do not use auto ranging, as it is unreliable with a magneto.

How do I know if my Briggs and Stratton coils are bad?

Replace the original wire with the in-line spark tester, and attempt to start the motor. Watch for the same intensity of a spark that you saw when the mower was cold, If there is little or no spark, the ignition coil is bad and needs replacement.

What is the coil gap on Briggs and Stratton?

Common armature gap ranges are .006 – .010″ and .010 – .014″. Armatures are often packaged with a shim to assist in setting the gap. Index cards of the proper thickness also work well. Unhook the spark plug wire and secure it, removing any batteries, if equipped. Remove the old ignition coil (armature) mounting screws.

How do you test Briggs and Stratton coil?

You have to inspect Briggs and Stratton ignition coil symptoms like no spark when you crank the engine, poor spark, poor rotation power, and weird sound for a twin-cylinder motor, etc. Moreover, according to our guide, you can test the ignition coil with a multimeter and rule it out as a bad one indisputably.

What is the gap on Briggs Stratton?

Briggs & Stratton recommends that the air gap setting for the armature be set at 0.010-0.014 inches, or 0.25-0.36 mm; the spark plug gap should be set at 0.030 inches, or 0.76 mm. Valve clearance, with valve springs installed and piston 1/4-inch or 6 mm past top dead center, is intake valve set at 0.005-05007 inches, or 0.13 – 0.18 mm, and exhaust valve set at 0.009-0.011 inches, or 0.23-0.28 mm. Make sure that the engine is cold when you measure the valve clearance.
