Hey man;
I'm assuming you mean at the clip where it attaches to the board. If so there isn't a lot you can do to fix it safely. You can try solder (I wouldn't if you haven't had a lot of experience), but the safer choice is to try to get one off Scotti. He may have a used one lying around for a decent price. If it's at the battery end your in luck. Just strip off the rubber seal, solder the wire back on and cover the end back up with black electrical tape. My advice - call Scotti. Luck to ya man.
