@p5ychojoe13 use a sharp box cutter (razor blade etc.) then gently cut a lengthwise slot into the out insulation only. You can now either pull the inside wires out of the insulation or cut the insulation away. Inspect the wires for any obvious broken strands. Use a multimeter the check each wire for continuity. If you have a broken wire, you can cut the broken part out and reconnect the wire via soldering and some heat shrink tubing.
