    • Testers are fully protected from short circuits.
    • Testers detect open circuits, ground shorted circuits, cross shorts between circuits and reversed wiring.
    • Circuits such as turn signals using a flasher to simulate actual tractor-trailer connections.  In addition to testing circuits per acutal operation, the tester monitors excessive turn signal current and trips a breaker should the tester detect a partial short.  This is important because the flasher unit in the tractor can easily be damaged with excessive current in the turn signal circuits.  All testers include a master power switch to disconnect power.

    • All testers include easy to understand test instructions.
    • The testers all detect and display ABS brake signals from the tractor.
    • All testers are fully warranted for one year from defects in parts and workmanship.
