    Gotta Ford f150 for light plowing. While I was plowing the battery voltage went down had to jump it after I jumped it acted crazy. Kept cutting off when I put it in gear. when it was in park it idled low then cut off again even when I had my foot on the gas
    As I drove I had to keep restarting the truck Its not the altenator I just put a new one in. Installed a new battery still the same thing happened. Can not be the pump motor I was not using the plow the second time.
    Can this be the gas filter? Any ideas? I am thinking it has something to do with the fuel line but I can not be sure. Any experts who can give me osme advice?

    My suggestion would be: 1st - make sure you're battery connections are clean and tight. Make sure the alternator connections are tight.

    Then - take the alternator back to where you got it and have it tested. I wondered why you would say it wasn't the alternator. Then when you said you'd just got a new one, I suspected you got a rebuilt. Sometimes they're just bad.

    What year truck? Does it have an external voltage regulator? If it does I would have the voltage regulator and the alternator tested.....Last alternator I replaced, Autozone had every alternator in stock that fit my truck test bad... I always have them test it before I leave.......

    For a really Fast and Simple " Test " , Very carefully Hold a ScrewDriver against the Back of the Alternator at the Bearing. After You Feel the Difference Between a Good , Bad , and only 1/2 Charging ( one bad diode ) in the Magnetic Field ( Pull ) You will have Your answer while .
    But if not sure , try it on a Good Alternator First.
    Who cares what the Amps are ,if they are not all there , replace. Yes I do have ALL the Testers in My Hobby Shop.
    The Last one I got at a Consumer Auto Parts Store on a Sun. For a customers Pick Up. I got two bad ones from My Local store , there tester Didn't work ? ,or they didn't know how to operate it. They didn't have any more and I had to Go 15 mi. to another store, The Manager, a really cocky female informed Me that this was the last one I was getting from them as I was obviously doing something wrong.
    So I made Her Reluctilantly Put it on " There Tester " ,
    Guess What , I took My CASH Refund and Waited till Mon. , and bought a " Real " Rebuilt Alt.

    I must say thanks for all the advice! I am dying to try that trick out! LOL Bad Altenator! That is tooo funny! LOL I bought it from THE ZONE purposely because Pep Boys is KNOWN for bad altinators..That is their M-O
    I asked the Zone if I can have a baigger altinator they told me one size was made for my truck though I knew that was bogus I have a 1991 but that trick is really niftY with the altinator. I know you can test out a pump doing that but didnt know about the alternator!
    You guys! WOW your the best!

    There was a post here last week about a company that sells Beefed Alt's for Fords and others no core required , and prices were not that bad.
