None of us can come close to causeing Power Pole fork truck connectors to EVER FAIL.
I rebuilt fork truck power leads very often & my final test was to put the truck against the wall and and floor it for 1 second.
Then I ran the truck up & down a steep hill to really heat up any loose connections or blow out other bad ones.
Never failed a test.
You CAN NOT damage fork truck pins & springs in them.
