I think there are supposed to be limit switches to prevent all this, but they don't seem to work on mine.
You could also burn out the fuse and/or strip gears by accidentally reversing direction of the jack without allowing it to stop in between.
Took "Daisy" to the dealer today, and the jack is now operable again. Problem- the timing was off, and the jack would not stop. It would continue to run and the gears would strip and blow the fuse. The dealer had to take the parts from another AS since they don't keep these parts in stock(ie-limit switch, gear jack fiber). They reasured us that these jacks are very good and seldom come in for repairs.
The whole dealerships' staff including the owner, gm, service gm, sales personal, were all talking to us. We were out in 1 hour. Everyone was making sure things went okay. Good bunch of folks at Marty's USRV at Berkley,MA.
