  • A single pole charge cable only carries a positive (+) charge, while a dual pole cable has an internal ground allowing it to carry both a positive (+) and negative (-) charge to the liftgate batteries.
  • An insufficient ground can cause the current to seek out another ground source, such as the ground wire found in a 7-way cable. If the return power routes through the 7-way cable ground it will melt it and ruin the cable.
  • Undercharged liftgate batteries will cause the liftgate motor to power directly from the tractor, which can overload the charge cable resulting in damage from overheated wires.
