How do I know if my ignition lead is bad?
Usually faulty ignition cables will produce a few symptoms that can alert the driver of a potential issue.
- Decrease in power, acceleration, and fuel efficiency. One of the most common symptoms of an issue with the ignition cables is engine performance problems.
- Check Engine Light comes on.
- Visible wear or damage to cables.
What is a spark checker?
Product Overview. Use this ignition spark tester to check the condition of the ignition system at each cylinder. The spark tester connects between the spark plug and spark plug wire to troubleshoot dirty spark plug connections, defective points and bad cables or connections.
What is an ignition tester?
A handy tool to check ignition spark without removing the spark plug. The tool is specially calibrated to measure ignition voltage. Works on both standard and electronic ignition systems.
How do I know if my spark plug leads are bad?
Common signs of failing spark plug wires include a decrease in power, acceleration, and fuel efficiency. In addition, the engine light coming on or visible damange to the cables can be signs of a failing wire.
How many ohms should a spark plug have?
When spark plugs are new, the resistance value is between 500 and 3000 ohms. As the plug ages, values below 5000 ohms are acceptable. But once the plug’s resistance value exceeds 5000 ohms, the plug should be replaced. If a spark plug falls off a workbench or is dropped, it’s possible for the carbon resistor to break.

Can you test a spark plug with a multimeter?
An Ohm meter, which is part of a multimeter, can only check a spark plug for a short circuit or a breakdown of insulation resistance. A good spark plug should show an open circuit between the center electrode and the tip. Any resistance at all would mean the plug is bad.

Do I need a spark tester?
When testing a coil or secondary ignition component it is important to use a tester that will create this much voltage. Without it, a high tension leak or a weak coil can be overlooked. A bit repetitious, but you need to use the same diagnostic strategy each time you approach an ignition system problem.
Can I test a spark plug with a multimeter?
What kind of lead does a spark plug use?
Ignition Leads. Alternatively known as a high-tension (HT) lead or spark plug wire, an ignition lead plays a vital role in an engine’s fuel ignition system.
What kind of ignition lead do you need?
What type of ignition lead do you need? The majority of standard ignition leads for vehicles is 7mm in diameter but 5mm cable is used for mopeds and garden tools and 9mm cable is used for veteran cars. At The Green Spark Plug Company, we have a vast range of HT lead.
Do you put test lead between coil and spark plug?
Once the coil is disconnected from the spark plug and has its multi-plug refitted, place the extension lead between the spark plug and the coil. Ensure there is a positive ‘click’ into place at both ends. If for any reason there is not a secure fit then the test lead should not be used.
When to use HT extension leads for secondary ignition?
HT extension leads are designed to aid diagnostics on secondary ignition circuits by allowing an HT measurement to be made when there is no, or limited, access to any spark plug leads. The leads are specifically designed for use with the MI074 Secondary Ignition Pickup.
