Tester Confirms Electrical Connection

Why won't that lamp light? Why does that train always stall right there? Why won't my R/C car run? Our circuit tester makes these questions easy to answer.

Place one probe on each side of your connection point.  If the red probe lights up, you know you have a good connection.  If it doesn't, you need to fix it.  Fast and easy to use.  Perfect for testing electrical continuity of model railroad track.  Overall length: 24 inches.
