Repair...Off-Board charger
 

Anyone know where I can get my Seg. off-board charger repaired?

You did not say what the problem with your charger is but you might want to know that there is a current recall for the chargers. http://www.segway.com/support/recall-information

Charger repair ?
 

I'll take another shot at answering your question. I suggest that the best way to handle this is to talk with your local segway dealer who will probably need to send it in to the mother ship, Segway Inc. It looks like your nearest dealer is
