    The heavy one supplies current to the battery. The thin one is used by
    the alternator's built-in regulator to sense battery voltage. This is
    to compensate for the voltage drop in the current carrying cable.

    A term often used to describe this technique is "remote sensing".

    No, I don't think they are the same. The green wire grounds the
    housing of the appliance (for safety), in case there is a short in the
    circuit. Will the appliance work if you connect the green wire in
    place of the white wire, no. The green wire is connected to the
    appliance housing in case of an electrical short. The white wire is
    the common (ground) return. Do not connect the green wire to the white
    wire! Listen to the advice already given. These guys know their stuff.

    The main problem in applying Darwin's theory to humans, is that animals
    rarely sell their houses. Some barter, or steal them, but they are usually
    "as-is", and the new owner lives with the consequences as their actions have
    produced. Our situation relies on laws to protect ourselves from each
    others' stupidity, and although not a perfect system, still allow for
    someone to sue you for everything you have if your wiring causes injury, or
    death to another.

    Luckily, you have benefitted from the free advice of several learned people
    here. I hope you have learnt more than just basic power circuit safety...

    Of course the proper, NEC-approved way to convert 2-prong outlets to
    3-prong without installing a proper ground is to use GFCI outlets.

    The NEC also happens to allow the ground and neutral to be tied
    together in some special circumstances. For example if the circuit
    only supplies a single appliance like a dryer or stove (some 3-wire
    corded dryers connect them internally).
