The OP stated that the wire got "warm, not hot". I was only stating a rule of thumb that if you can leave your hand on it then it is likely no more than 50C. I know of no common wire that is rated for less than 75C and a lot of wire is commonly rated for a much higher temp. With any circuit that can run at max for a while - like an alternator, or a battery charger, the wires will get warm to the touch and warm under those circumstances is not a problem. Is the heat lost energy? Sure, but at some levels it is unavoidable.
