Finding dead or malfunctioning coils and plugs can be hard work. The GTC505 makes ignition troubleshooting quick, easy, and painless. It’ll help you, and the people depending on you, get moving again!
The GTC505 is the product of 20 years of work (by GTC) on ignition diagnostics.
This tool will tell you exactly what’s going on with any spark ignition system as soon as you put its sensor by your coil (or spark plug wire). Swapping coils and other components in and out until you figure out what’s wrong is slow, tedious, and wasteful. The GTC505 will take the guesswork out, so you can be confident that the problem will be solved on your first try.
