So it doesn’t look like a pancake, but pancaked wires short-out just the same. The first step is to separate the wires. I just use my thumbnail and pull them apart. You can see how the separated wires look. The next step is to decide if you can still use the wire, or if it is too far gone. I will usually reuse the wire if less than about a quarter of the copper is damaged. If it is cut further than that, or if it really is pancaked, cut the damaged wire out.
