    I have a 93 F250 with a 351W and stock alternator. I am planning on plowing for the first time this winter. I was wondering if the stock alternator is fine or if I should upgrade it and if so to what. Also I have a full size light bar that draws about 50-60 amps with all the lights on. I probably won't run all the lights on because of this but just wondering what you guys think.

    Use the search function on the gray line above the page. Search ' Charging" - "alternator upgrade" etc.
    There should be a few hours of reading there. You can buy bolt on replacement alternators that put out big time amps.You have to add a bigger gage wire to the batteries to handle the amps. Or you can have yours upgraded for about a dollar - fifty or so an amp at a rebuild shop. You still have to add a bigger gage wire to handle the amps.
