+ could short to a terminal, the frame, the starter solenoid, (future corbin metal seat pan?). There is packing tape now but if it needs taken care of anyway before I sell, have it serviced, or some white night yahoo tries to stick his head under my seat while I'm fixing something else. You have to squeeze the metal ecu box out over it to swap eproms. It's Italian and old, battery is ok but other things get looked at.
