clean and cut-away the plastic around the wire on the transformer,
then meter it to the other windings to see if it's open/short.
if it looks o.k. then solder a new cable to the stub and clean it again with isopropanol,
then cover it with lots of thick rubber HV sealant or HV epoxy.

dont use the original cable, the insulation is to old - ask a tv repair shop for a dead Lopt from a tv that's not too old to remove the cable from.
or salvage one from an old pc monitor from the side of the road.
