Review on Lisle 19380 Spark Tester by Genene Locson

Inductive; allows you to see the current from the coil through the wires to the connectors through a stronger or weaker flash. Check the coil wire and each connector wire without having to remove connectors or wires. You need other tools to get more specific results for specific parts. ; This tester is handy for the glove box or general tool box. Example: I found on my V8 that one wire/connector is weak and the other side has excessive crossover (current jumps through one wire's shield to adjacent wires) and added an extra wire clamp from the coil wire to the two connector wires, removing the spacers and tying the coil wire away from other wires, unplugging and cleaning the defective connector is all I need until the next planned build. for the tool box.
