Drilled into rear air wire ( No longer have drill ) from roof on 2010 Allegro 32ba and now have a short. would like to replace wire not sure how to get to it???
Just disconnect it at its origin and run another one. Or, since you know exactly where you damaged it, make an opening in the ceiling to repair that section and put some sort of access panel over it. If it's small enough you can use an adhesive backed, round, plastic plate that is used to cover dings in the wall made by door knobs.
