    Hi guys I got my truck out for the first time and after about 4 hours from the up and down of the blade my truck killed and battery was almost drained all the way. I jumped it and it started right up. I turned all the lights off, radio, heat and it went smooth for the last hour. It has a new battery in it.

    Here is my question, will dual battery's fix this problem, better alternator, or both. I looked under the hood and where the 2nd battery is on my 97 F350 PSD is where the washer fluid is on this truck. Where would I put it? Move the washer tank?

    Thanks
    Patrick

    What size alternator is in the truck now? I think my 90F250 came with a 70 amp, which I upgraded to a 130. Lights still dim when moving plow, but that's it. Maybe your alt is just on it's last leg.

    I'm not sure what size it is. I just got the truck about 2 weeks ago. I was going to take it in this morning to the garage up town but he got backed up towing cars so he couldn't't get it done today. I am going back out tonight and I think that will be it for a while. I am going to toss a battery on the floor of the pass. side and a booster pack just in case it dies again and I need to jump it. I think on Friday I will just buy the biggest alternator I can get and see if I can find a place to mount a second battery.

    I had the same issue with my 96 F250 last year and I put in a new alternator (larger) and that fixed the problem. I still run one battery the only thing is that the lights dim a little when I move the plow.

    If you added another battery it would not fix the problem but it would take twice as long for the battery's to go dead. A bigger alternator is the answer but the best setup would be both a larger alternator and a second battery. Get a bigger alternator first then another battery if you find a place to mount it.

    Thanks guys I just got back in from last night and it worked OK. I was a little more attentive and used the amount of snow to lift the blade then hit the hydraulics. Worked out OK but I am going to get a new alt tomorrow and see if I can find a place to mount the second battery. It was the first time I used the truck so I found out a little to late and it had to be a big storm to. Oh well thats the way it goes. This is my first year back plowing after a 12 year break. I did it all during school until I was 21. When that truck died I remembered why I stopped in the first place. The guy I drove for had some really rough equipment and use to break down at least once a storm.

    Thanks again
    Pat

    if you have close to a 100,xxx miles or more the brushes are prolly shot in the alt and it is time for some new ones. Do you have a gas truck , i assume so, i would upgrade to the g3 alt that came on mustangs and taursus and waht not, they were 130 amp from the factory. It will also be cheaper on the wallet. I built my 200 amp for 40 bucks, new they are closer to 250 bucks or more.

    this is a list i picked up from the wrecking yard when i was seraching for a 3g alt

    All of these Ford vehicles had the 130amp 3G

    (1994-95) Ford Mustang 5.0L
    (1994-00) Ford Mustang 3.8L
    (1994-97) Ford Thunderbird, Mercury Cougar 3.8L
    (1990-95) Ford Taurus, Mercury Sable 3.8L
    (1993-99) Ford Taurus, Mercury Sable 3.0L
    (1995-98) Ford Windstar 3.8L & 3.0L
    (1991-94) Lincoln Continental 3.8L
    (1992-97) Ford F Series Pickup
    (1992-96) Ford E Series Van

    there is a large case version and small case...IIRC the large case is close to 6" in diam. If you don't have a large case and go to put it on yours you will more than likely have to clearence the brcket slighty.

    I got a Powermaster High Amperage Black Heat-Transfer Alternator 349.00.
    It puts out 125 amp at idle and 200 amp max. I did some reading on a ford truck forum and a lot of guys are using these alternators and they seem to be the best out there for heavy draw without altering the mount or wiring harness. I will let you guys know how it works out should be here on Tuesday.
    If you want to look into them here is the link where I ordered it from.
