I have a problem with my z24 engine.

My question is this since the idle circuit needs 12 volts consistently to run right.
If a wire insulation shows a big fat lump, does that mean that the copper wiring inside it is broke/snapped and is cutting off the 12 volts from reaching whatever it needs to reach?

Potentially, why don't you strip the insulation off and have a look what's going on under there? Or measure wire resistance with a multimeter

that's exactly what i was thinking.
Sorry, I'm just trying to learn about how car engines work.

Here's a scamatic, try making sure all the wires are in good shape, they have a tendency stretch and rot. From my experience the problem may be from the carborator itself. Try searching on 720 world or other Nissan forums.
