Features and Benefits:

One person can now test all. The 7 Round Pin Tractor Trailer Circuit Tester does ‘one-man testing’ for male and female 7 round pin tractor trailer plugs and much more. It allows the jumping of current to a dead circuit for emergency situations so you can still drive the rig. It slides over the 12 volt supply pin so you can touch any of the other pins to power them up. Like if their clearance lights are out they can jump the circuit and make it work.
