FAQs
Can this be used on motorcycles?
Yes, it is compatible with most standard ignition systems, provided they do not use NGK type F HT caps.
Is the bulb easy to replace?
Yes, the test bulb is designed to be easily accessible and replaceable when necessary.
Does this tool work with coil-on-plug systems?
This tool is intended for systems with external HT leads. It may not work directly with coil-on-plug systems unless an extension lead is utilized.
How do I know if the tester is compatible with my vehicle?
Check your spark plug leads. If they are standard push-fit connectors and not NGK type F HT caps, the tester should function correctly.
What is the total length of the device?
The SIL080 features a 270mm lead for testing reach.
Troubleshooting
The tester light does not illuminate during cranking.
Verify the tool is securely connected to both the plug and the lead. If connections are solid, check the bulb for damage or looseness, or test on a known working cylinder.
The bulb appears dim or flickering.
This may indicate a weak ignition coil or high resistance in the HT lead. Inspect leads for wear or corrosion.

Setup, Compatibility & Care
Ensure the engine is completely turned off before installing or removing the tester to avoid accidental shocks. The tool is designed for standard automotive ignition systems but is strictly incompatible with NGK type F HT caps. After use, inspect the cable for any signs of insulation cracking or heat damage. Store the device in a cool, dry place to prevent moisture buildup in the spark gap components. If the indicator light fails to glow during a known good test, check the bulb connection or replace the bulb element.
