"One-Man Testing" for Male and Female 7-Way Round Pin Tractor Trailer Plugs

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.

  • Troubleshoot tractor trailer circuits
  • One person can now test all the lighting
  • Allows bypassing of troubled circuitry while on the road
  • Eliminates guesswork
  • Packaged with an extra jumper connector
  • “Winged” grip for easy removal from electrical connector

 Emergency Bypass Feature

The 7 Round Pin circuit tester can also be used to bypass shorted circuits using the supplied jumper.  

The instructions below better explain this feature:

  • Plug the unit into the cable end and identify the faulty circuit.
  • Unplug the unit and unscrew the pin next to the unlit LED (except for the auxilliary circuit).
  • Install the flat brass jumper over the center pin and bend the tail down into the hole left by the removed pin.
  • Plug the cable with the 7 Round Pin Tractor Trailer Light Circuit Tester attached, into the trailer and you are on your way.
