The Laser HT Lead Ignition Spark Tester is an automotive diagnostic tool that confirms spark presence quickly. Visible spark confirmation gives confidence when tracking misfires and ignition faults. Is the tester suitable for engines with recessed plugs?
⚡ At a Glance
- • Spark Detection: Detects spark by connecting inline between spark plug and HT lead, with bright, easy-to-see indication
- • Best for: Home mechanics and workshop technicians diagnosing ignition faults and misfires
- • Not ideal for: Engines with deep recessed spark plugs, where access prevents proper connection
Four inline HT lead testers connect between spark plug and HT lead to reveal spark activity. RoHS compliance confirms components meet restricted substance limits.
Visible spark confirmation – with inline connection between spark plug and HT lead
Connects between the spark plug and HT lead, allowing the ignition arc to be observed externally during cranking. User feedback highlights a bright, easy-to-see spark indication that shows when a lead is firing.
Quick visual confirmation of whether a lead is producing a spark, removing the need to remove plugs for an initial check. That speeds up diagnosis of misfires and intermittent ignition faults.
Multi-lead testing convenience – with four HT lead testers included
Supplied as a four-piece set of HT lead testers, suitable for checking multiple leads on multi-cylinder engines. Each tester plugs inline so different leads can be checked in turn.
Test up to four ignition leads without improvising, making it faster to isolate faulty leads across cylinders. Suitable for routine checks and fault-finding in a busy garage.
Regulatory compliance reassurance – with RoHS compliant components
RoHS compliance means the components conform to restrictions on hazardous substances used in electrical equipment. The label indicates materials meet recognised environmental and safety limits.
Reduced concern about hazardous materials in workshop tools, useful for workplaces that track compliance. Provides peace of mind when adding the tester to a professional toolset.
