    if you're going to be in there replacing the alternator in the first place, it's not going to be that much additional work at all.

    Battery to chassis is super simple.
    Alternator to battery positive can be done while have everything apart to replace alternator.
    And chassis to engine will be about as easy as battery to chassis.

    All it requires is some wire and some ring terminals.
    I have a 2002 Galant. But i ahve to install inline fuses though rite? What exactly is Chassis to engine?

    So basically then neg term on the battery goes to the chassis,

    The alternator pos goes to battery pos

    Chassis to engine: your car will have a grounding point on the block. This is usually fairly small or a flat braided wire.

    As for the fuses, the only one of the big three that you might consider fusing is the alternator to the battery, and even then, it's only if you really want to. For competition, it's a must, but for the average every day Joe, not a necessity.

    As for the rating of the fuses for the rest of the stuff in the car like your computer and car audio stuff, total up your total current draw (amperage), and get a fuse close to that (a little over is ok, but nothing major - say your computer pulls 15 amps, a 20 amp fuse would be ok). There's also the thought of fusing the wire and not just the components, in which case you would use a fuse that would protect the wire from burning up....if you're interested in doing that, would need to find a chart that would describe all the different fuses needed for the different size wire....or just ask specifically and I or somoene else can answer.

    As for the size wire to use, specifically for your grounds, ALWAYS use the same size if not larger than what your power is. Remember, it's one continuous loop, if you go smaller on one area, you will create a bottle nexk.

    FWIW:

    The proper Gauge Wire based on current demand and length of run:


    The proper battery size based on total RMS wattage of system:

    sheesh - a 180 amp alternator is WAYYY more than enough on your system.

    if you can get a smaller one for less $$, I'd consider it....lol

    I think there over rating it.... there saying that you need 10 more amps just to add a 100w amp

    a 180 will definatly do it all on it's own, & you won't need any bandaids like a cap really.....
