Are you talking about the gimmick cap wire? This is a wire which connects to the primary winding terminal and wraps around the secondary winding with no actual connection at the opposite end. It serves a a very small coupling cap which increases sensitivity at the high end of the band.

If the actual primary or secondary winding wire is severed where it connects to its terminal, then you can try splicing it with a small piece of similar wire. This should not be a problem as long as you make a reliable solder connection and keep the wire length short.
