Revolutionary Tech Inside the PST-100 Spark Tester

Feel that frustration when diagnosing ignition problems? We created the PST-100 because standard testers leave mechanics blind. See exactly what happens inside combustion chambers.

Instant visual verification shows spark intensity and consistency. The high-resolution display reveals what multimeters miss. Know your spark plugs' true condition within seconds.

Why Pros Choose PST-100 Over Generic Spark Testers

Generic tools fail marine technicians daily. Corrosion eats cheap testers. Saltwater kills inferior products. Your outboard motor spark tester must survive harsh conditions.

The PST-100's aerospace-grade aluminum casing laughs at corrosion. Sealed connectors block moisture intrusion. See why 87% of marine technicians upgraded last year?

Remember that flooded engine last season? Our patented pressure chamber simulates real-world conditions. Don't trust diagnostics made in perfect lab environments.

Precision Solutions For Every Engine Type

Lawnmowers. Chainsaws. Generators. Marine engines. Each requires specific testing protocols. Your universal tester delivers inaccurate readings? That ends now.

Select engine profiles directly on the OLED display:

• 2-stroke mode adjusts for oil residue

• High-Compression mode tests performance under load

• Marine setting factors in humidity variables

Diagnose that stubborn outboard motor fast. The small engine inline spark tester attachment fits cramped spaces. No disassembly required.

Real-World Success Stories

Bay Area Marine Services slashed diagnostic time by 65%. How? Technicians spot weak coils before failures occur. Preventive maintenance became profitable.

"Our small engine inline spark tester pays for itself weekly," says lead technician Mike Rostov. "The pressure-simulation feature found issues our old tester missed completely."

Landscape company Greenscapes cut plug replacements by 40%. How accurate are their diagnostics? Their warranty claims dropped to zero. Equipment uptime increased by 22%.

FAQS on pst 100 spark tester

Q: What is a PST 100 spark tester used for?

A: The PST 100 spark tester is a tool designed to safely and accurately diagnose ignition system issues in small engines. It allows users to visually confirm the presence and strength of a spark without removing spark plugs. This helps identify misfires or weak sparks in lawnmowers, chainsaws, and similar equipment.

Q: How do I connect an inline spark tester to a small engine?

A: Simply disconnect the spark plug wire from the engine's spark plug. Attach the PST 100 tester's boot terminal to the plug wire, and clip its ground clamp to the engine's metal frame. Crank the engine to observe spark intensity through the tester's clear viewing window.

Q: Can the PST 100 be used on outboard motors?

A: Absolutely. This spark tester works on outboard motors by connecting between the ignition coil wire and spark plug. Its waterproof design handles marine environments, while the bright spark display helps diagnose ignition failures even on wet or exposed engines.

Q: Why choose this tool over a standard spark plug test?

A: Unlike risky methods like grounding plugs against metal, the PST 100 provides safe insulation from electrical shock. It shows actual spark voltage through its calibrated gap system, eliminating guesswork while protecting sensitive electronic ignition components from damage.

Q: Does this inline tester work with all ignition types?

A: Yes, the PST 100 is compatible with traditional points-style, electronic (CDI), and magneto ignition systems common in small engines and outboards. Its adjustable gap settings accommodate voltages ranging from 5kV to 40kV for precise diagnostics across different engine types.
