Spark Checker Tool

Here's a handy tool to carry in your road going tool kit incase your car won't start. Place this "checker" inline with the spark plug, turn on the key and pull the starter cable on the solenoid to spin the starter (make sure it's in neutral first, of course) and this gizmo will tell you if you have spark by lighting up with each pulse from the distributor. No light=no spark! This is a handy tool you'll keep for life.
