    During storms it seems like the battery cant keep up with the plow and the strobes. It happens on all the dump trucks (3 04 v10's) and not on the single wheel 5.4 trucks. What gives, problem still happens with new batteries, been happening since new. Is the solution to wire up 2 batteries? Where are you guys placing a 2nd battery?

    Is there a larger Alternator available? What the difference in the Battery's and Charging systems on your V8 trucks?

    Make sure all the electrical connections are good and clean. Especially the grounds.

    Did the truck get ordered with the plow prep package? The plow prep alternator has a higher amp rating. Check the one that is installed. I have seen some alternators charge at idle but drop out around 1100-2400 RPM's. So do check that as well.

    I bought mine from here http://www.dbelectrical.com/

    I got the 220Amp alt, and have no complaints. I bought my starter there too

    how old are your batteries?

    i got the 220 for my powerstroke also, and i just got a new high torque starter in the mail have not had time to put it on yet, i had also ordered some other stuff from them. seems to be good so far, fast shipping. http://www.db-starter-alternator.com/

    and as for your problem you need 2 batteries and upgrade your alternator to a larger one, espcially if your dumps are electric ove hydalic, that sucks some power.

    We change out the battery's every 2 years, and the trucks have the plow prep package. Think we can get away with just changing out the alternator to a high amp one? Is anyone else having this issue with the v10?

    same kind of thing

    I have the 2010 F350 V10 ext cab with the plow prep provisions and i find when i am using it for a while the lights start dimming really bad and the plow starts moving a little slower and I only have about 3500KM on it. I have'nt had it checked out but if I do I will let you know.

    A good automotive component rebuild shop can build up your stock alternator for about $1.50 an AMP. So it will fit in the same place.
    Use the search function on the Gray Line At the Top.
    Search: Charging, low power, duel batteries.
    It's an issue that's beat to death many times here. You will have hours of reading come up.
    It's a very common problem, most here has faced it at one time or another.

    look up american armature they sell their own design high output alternators for emergency vehicles,hopped up stock alternators never last,not designed for the added heat of higher output.

    You definitely should be running at least two batteries. You can probably put the second battery in the engine compartment.

    Well i believe for ford you can put dual alternators? (I think?) If not there is many ways this problem can be fixed. Like what makes you think the battery's not keeping up, what is it doing?
