    This question is for anyone with a new Ford. I have a 2005 F-250 (Gas Engine with plow pkg which on ford seems to be just heavier springs), and I am getting a Fisher V-Plow installed on it next week. I am toying with having them install strobe lights in all 4 corners as well. How well does the factory battery/charging system hold up to all of these accessories? I have concerns with being at a low idle with lights, heater, and moving the plow. Can the factory system handle everything drawing on it at once? Any advice would be appreciated.:)

    Check your build tag for the truck it should state what amp alternator was installed. A 100 amp is at least is OK. Run the least amount of lights you can
    (example: no headlights in a lighted parking lot) No big 20 amp draw light bars.
    Watch your battery/amp gauge Battery should be at 12.5 --> 14.5, amp's on the + side. your headlights will start to dim after plowing a while and you hit the plow switches.
    Use the search function on the blue line above. Search: low power,lights dim,duel batteries,bigger alternator etc. for more info
    Expect to replace the OEM battery after the first year of plowing.

    i believe the truck will have a 130 amp alternator. you shouldnt have any problems with the alternator keeping up. if your truck doesnt have dual batteries, i would look into adding a second one. you dont have to but it would help.

    Just a thought also....I have an 04 and just last week (during the "big snow") I had a fuse blow. It powered my parking lights and interior dashboard lights.

    So, you may want to bring some extra 15 and 20 amp fuses with you, just in case. I think it blew due to the plow lights. I have Saber's and they draw power off the parking light system.

    Just my .02. You'll enjoy pushing with that truck. Have fun!!

    Thank You for the responses. It appears that it is rated at 130amps stock under ideal conditions. I'll take the advice of keeping off all the accessories that I don't need running.

    Thanks Again

    Check out the link in the pic forum.. Shows a dual battery setup for the gas superduty..relocates the canister to under the intake./I am ordering one this week. I run truck, plow, sander, LED's, reverse lights on one battery..truck has shut off when it runs too low.

    Keep in mind the alternator only puts out 1/3 of it's rated output below 2000RPM. / Keep an eye on the volt gage it should be 13.5 --> 14.5 \
    When it drops below that range your getting behind the 8 ball on battery reserve. If the truck starts to sputter when you run the pump let go of the switch/button. Computer's need a certain voltage to work,you drop below it and the engine quits. Nothing worse then the silent sound of winter in a truck that will not start.
