How do you test a distributor Ignitor?

If you want to check the ignitor, disconnect ir from the coil and put a test light at the coil wires. Crank the engine, you should have a blining light if the ignitor works.

How do I test my ignition control module?

Connect the ground lead from the 12-volt test light to the negative terminal on the ignition coil. Have your partner crank the engine over several times. Your test light should flicker on and off. If so, your module is working properly and no further testing is necessary.

How do you check a spark without a spark tester?

An alternative method to check if a spark plug is firing is to remove the spark plug from the engine. Plug the spark plug on your ignition coil. Ground the threaded part of the spark plug to the engine block. Crank the engine and see if you are noticing any spark at the spark plug tip.

Should I see a spark on a spark plug?

If no visible spark or glow is present, then you can be sure that no spark is occurring at the all-important tip of the spark plug. Does this mean the plug is bad? Not necessarily. The spark plug could be bad, yes, but lack of spark can also be caused by a fault somewhere else in the ignition system.

What happens if your spark plugs are not gapped right?

Spark plugs that are not gapped properly will cause the engine to either skip firing, or ignite too soon in the compression stroke. Properly gapped spark plugs also remove heat from the cylinder ignition chamber. The heat range of a spark plug is defined as its ability dissipate heat from the tip.”

What will happen if the gap is too wide?

The customer may experience loss of power, misfires, spark plug fouling, increased plug wear, or poor gas mileage. Too small of a gap may give too weak of a spark to complete the combustion process within the engine; too wide of a gap can lead to the spark plug not firing correctly, causing misfires at high speeds.
