Question about Volvo S40
Seems to me like a voltage meter would be a good place to start, to see just how much current is running through that wire. Check it in several key positions--off, on, starting, running. That should tell you a lot. It could be that power is being supplied at a time when it is not required. In which case, your ignition switch might be involved in the issue. Or a poor contact is making the wire act like an element instead of a conductor.

Most likely...seems like you have a handle on it. There may be wiring diagrams available, for example Chiltons manuals...To my knowledge there exists no "internal" wiring diagrams for alternators of any make.

Removing the two smaller wires stops the exciter current to the alt which stops it charging.
Usually if a wire is getting hot its because:
A: Current overload..
B: Corrosion in wire restricting current.
C: Corroded terminal.

Are you consider yourself a handy person?
Swap the coil and see is the misfire going to follow to another bank of cylinder.
You has total of 3 coil in your engine.
Do a detail record map and switch the two coils.
A replacement aftermarket coil is oil $46 w/one year warranty and $55 will get you a life time warrent coil.
Do the swap and see what happen.
A leaky/failing injector can also cause the same problem.
Do a Chevron Techron fuel injector clean ran and highway ran.

Car not starting or turning over indicates towards multiple possibilities.
It can be issue with battery or weak battery. But if battery checks out ok, then
it can be starter issue or faulty alternator or problem with low fuel pressure
or no spark at spark plugs due to dirty spark plugs or faulty
ignition coil or injectors getting cracked or dirty and needs to be cleaned.
To confirm the problem, the basic troubleshooting is required.
