Spare coil with a few loose outer windings: trim and resolder
A coil whose last few turns have come unwound outside the wrapper can still be used if its resistance and continuity are right. Cut off the loose turns (or rewind them tightly), scrape the enamel off the new end of the wire, and solder it back to the lug; losing a handful of turns out of more than a thousand makes no practical difference. Do not leave loose wire where it can rub on the pop bumper body and short.
