FAQS on spark lead tester

Q: What is a spark lead tester used for?

A: A spark lead tester checks ignition system integrity by detecting voltage leaks or weak sparks in spark plug wires. It ensures optimal engine performance and diagnoses misfires efficiently.

Q: How does the PST 100 spark tester differ from standard testers?

A: The PST 100 spark tester offers adjustable gap settings for precise spark intensity measurement. Its rugged design and LED indicators make it ideal for automotive and marine diagnostics.

Q: Can an outboard motor spark tester work on other engines?

A: Yes, most outboard motor spark testers are compatible with small engines like lawnmowers or motorcycles. Ensure voltage ranges match your engine's specifications before use.

Q: Is it safe to test spark plugs without a dedicated spark tester?

A: Manual testing risks electric shock or ignition coil damage. A spark lead tester provides insulated, controlled testing for accurate and safe diagnostics.

Q: Why does my spark tester show inconsistent results?

A: Inconsistent readings may stem from faulty connections, worn electrodes, or moisture interference. Clean components and verify secure wiring before retesting.
