FAQS on spark strength tester

What is a spark strength tester used for?

Q: What is a spark strength tester used for?
A: A spark strength tester measures the voltage and consistency of ignition sparks in engines, ensuring optimal performance for automotive or marine applications.

How does the PST 100 spark tester work?

Q: How does the PST 100 spark tester work?
A: The PST 100 spark tester simulates engine load to assess spark plug performance by displaying spark intensity and detecting weak or inconsistent ignition signals.

Can a spark tester check outboard motor ignition systems?

Q: Can a spark tester check outboard motor ignition systems?
A: Yes, specialized outboard motor spark testers diagnose marine engines by verifying spark plug health and ignition coil output under simulated operating conditions.

Why use a dedicated spark strength tester instead of a multimeter?

Q: Why use a dedicated spark strength tester instead of a multimeter?
A: Spark testers provide real-time spark visualization and load simulation, offering more accurate diagnostics for ignition systems than voltage-only multimeter readings.

How to maintain a spark strength tester?

Q: How to maintain a spark strength tester?
A: Regularly clean contact points, store in a dry environment, and replace worn cables or probes to ensure precise measurements and device longevity.
