Automotive diagnostic tool for quick ignition checks, confirming spark at the end of the HT lead. Mechanics and classic-car owners gain confidence before cranking the engine with rapid visual verification. Is the Accuspark Spark Plug Tester a sensible addition to a home garage kit?
⚡ At a Glance
- • Fit and Compatibility: Inline connection that fits between HT lead and spark plug for straightforward hookup
- • Best for: Garage mechanics and classic-car owners who need a fast ignition check
- • Not ideal for: In-depth electronic diagnostics or ECU-level fault finding
Set of four testers supplied, designed to sit between spark plug and HT lead to confirm spark at the lead end. Established UK supplier with 35 years supporting classic cars ensures practical knowledge and availability.
Immediate Cylinder Indication - With inline visual indicators at the HT lead end
Each tester inserts between the HT lead and the spark plug, placing an indicator where the high-voltage spark should appear. Visual elements reveal whether spark reaches each plug without removing leads from coils.
Rapidly identify a misfiring or dead cylinder, cutting fault-finding time during routine checks and before road testing.
Simple, No-Fuss Operation - With a plug-in inline fit
Inline connection means no special tools or complex wiring are required; testers slot directly into the ignition lead route. The arrangement keeps connections straightforward and reversible for quick repeated checks.
Carry out ignition checks in minutes, making pre-start inspections and daily maintenance far less hassle in a busy garage.
Safer Coil Testing for Older Vehicles - Thanks to user-reported ECU protection
Users report that performing checks at the HT lead end reduces the need to disconnect coils directly, a practice sometimes linked to electronic control issues on sensitive systems. The design isolates the indicator at the plug end during testing.
Reduced risk when testing high-voltage coils makes the tool suitable for classic-car work where protecting electronics and ignition components matters.
