    thank
    's guy's i am checking them out ,i have a 105amp now thinking about a 130amp they say they charge 75amp at idle 200 at 1200 rpm .i don't suppose that it will cook the battery?under normal driving with out the plow .i like the idea they have of putting their 4 gauge fuse kit for the charging wire upgrade .

    A big alternator will not "cook" your battery. I installed the NAPA 155 amp kit in my truck. Made a big difference. You definitely want the larger charging cables, both positive and ground.

    I paid $220 for my 300amp from them (db electric)....figure in a little more for the HD battery cables and such and you'll be right around your $250 and have a kick ass system (so long as the rest of the electrical system is in good order!).

    If you're buying online DB Electric is tough to beat as their stuff is top notch. But, if you'd rather buy local head over to your local NAPA and pick up p/n 1N4807HO. It's a 100% new 200 AMP high output alternator with a full warranty that will bolt right on your 6.0 with no mods. They're around $250 (and no core needed) and you're getting a full 200 AMPS. They even come with a proof of performance tag in the box and are fully dyno tested. The last one I got actually put out a full 220 AMP at highway RPM's and 120 at idle. More than enough to power most anything. I have about 7 or 8 of them out there now and after a year (including a full plowing season) have nothing to say but good things about them. Very good bang for your buck. :nod:

    And yes like MCW mentioned make sure the rest of the system is up to snuff. All the alternator in the wold does little good if the rest of the system can't handle the amperage efficiently.

    Correct, increase all cables. 2 gage is good. It;s just the right size for the job but not too bulky. Use at least a 4 gage on the charge wire, bypassing the terminal block and heading right to tthe driver side battery.

    1 gage is BIGGER than 2 gage.

    No it's fine, but 2 gage is plenty for battery to engine connections.

    2000MCM is pretty beefy stuff. Going to wire my LEDs in my tailgate with it. I don't want them to have any voltage drop.........
