FAQS on inductive spark tester
Q: What is an inductive spark tester used for?
A: An inductive spark tester checks ignition system functionality by detecting the electromagnetic field around a spark plug wire. It helps diagnose misfires without direct contact. This tool is ideal for testing small engines and automotive systems.
Q: Can a small engine inline spark tester work on motorcycles?
A: Yes, small engine inline spark testers are designed for compact engines like motorcycles, lawnmowers, and chainsaws. They connect between the spark plug and wire to visualize spark quality. Ensure compatibility with your engine’s voltage range.
Q: How do I use the PST 100 spark tester?
A: Attach the PST 100 spark tester to the spark plug boot and ground its clip to the engine. Crank the engine to observe the spark through the tester’s window. A bright blue spark indicates a healthy ignition system.
Q: What’s the difference between an inductive and inline spark tester?
A: Inductive testers clamp onto spark plug wires to detect electromagnetic signals, while inline testers connect directly between the plug and wire. Inline models provide visual spark confirmation, whereas inductive versions are non-intrusive.
Q: Can the PST 100 diagnose weak ignition coils?
A: Yes, the PST 100 spark tester identifies weak coils by revealing dim or inconsistent sparks. A weak or orange spark suggests faulty coils, wires, or plugs. Always compare results with manufacturer specifications for accuracy.
