Lisle 20610 Inline Spark Tester

Quickly diagnose difficulties with all ignition systems. Connect the tool amidst the spark plug and the plug wire. The tool is double-ended to offer a straight boot and a 90 boot on one tool. With the engine running, the tool flashes a mirror effigy of ignition spark.

Nice tool, works well
By Rob K
I used this to help diagnose a possible ignition problem on a friends car. It’s connections are easy to use in a variety of circumstances. Only complaint is that it’s hard to see if it’s in direct sunlight, but I can’t think of any way around that issue. Would recommend this product to everyone.

Effective; gets the job done
By Michael Fletcher
I didn’t believe it at first when three of my four cylinders showed no spark. However, became a believer when it proved true (rats had chewed thru the harness in which the wires to the coils were located). Much easier than pulling the plugs and testing directly; keeps the plug firing rather than building up unburned fuel in the cylinder. Great product

quickly found that I had an ignition problem
By loosenut
well made and the straight/angled boots worked great. If it only had a way to self test that the light is working it would rate a perfect 5 stars. If you have no spark you wonder if the device is working or not. Minor issue….buy it anyway, its simplicity is its strength.
