No, it's just a wire, after all, but it's usually just thicker, to handle more current from an amp than a puny pickup on a guitar can swing- the cable itself is passive, unpowered, un-everything; but if it's a much heavier cable, or had a slightly oversize 9mm jack on the end, some careless git may have damaged the guitar's wiring by wrenching, pushing or pulling too hard on it when plugging it in or unplugging it. What kind of guitar is it, and did anyone look inside and see if a solder joint got broken yet? That's your first port of call.

Soldering isn't the highest skill in the world, and it's a necessary one for anyone in this line of work, so get to work learning a simple circuit. Check for dry joints and loose wires. There are plenty of schematics on the web to help you out.

Speaker cables are usually two conductor wire WITHOUT a braided shield.
Usually they are heavier gauge than guitar cables and line level cables.

You can use a shielded cable to hook up your speakers although they are usually way too thin of a gauge.
Some amps don't like the capacitance and electrical characteristics of braided wire.

An un-shielded cable like a proper speaker cable will not reject the RFI and other hum causing fields and thusly you will have LOT'S of hum.

It shouldn't hurt anything physically or electrically to use an un-shielded cable unless the speaker cables was plugged into the output of an amp.
Let's hope that wasn't the case!
If it was the case.... yes... your pickup probably got toasted.
