    Hi all, looking for some more help again . Have some snow coming tomorrow so today I went out
    and started the jeep to let it run and do my go through the process that I do . the jeep started fine
    and after letting it run for a bit I turned on the plow to go through the motions and it wouldn't move the
    relay motor was clicking but no movement. I turned the jeep off because I had to go get gas for my car and get some gas for the snow blower when I came home I sprayed the battery terminals and all my contacts with contact cleaner and went to start the jeep and it was dead . boosted it and it started turned on the plow pressed it to go up the jeep died and the battery was dead again . I know the battery is toast but my question is can there be enough juice in the battery to crank over the jeep but not enough juice to power the plow ? sorry for the long winded post but this is the first year I'm plowing for profit and I really don't want to let my customers down .
    Thanks Terry

    Take a look at the plow solenoid, then the power wires going to your plow.

    What dot the volt gauge say when you started it and when driving it to the station?

    Start with the battery, check the alt output then go from there

    don't spend money that you don't have to. Check the alternator and battery first. Don't throw parts at it.

    Should be good off the shelf; if it's down a little, it'll charge up. Check the dates in the battery though to get the newest one.

    When I started way back, we had to put the acid in the batteries, then charge them to sell them. If the battery is old your not wasting money. But you may have other problems. Use a volt meter and check the alternator voltage output.

    if the battery is more than 4 yrs old change it, if there is any side bulging, change it

    i usually use napa batteries, have had the best luck with them

    get a battery with high cca, cost more but worth it, expect to pay more

    The battery was definitely older than 4 years I'm thinking maybe 6 years old . Bought a new one from Costco and everything works again . Next question when I check the output on the alt should I assume anything over 12 volts its ok ?
    Thanks again everyone

    If you were testing this at idle, that's not that bad. Ideally you'd like to be 14.4_14.8

    New batteries generally come charged around 80%. This I know, because I've measured them with a good load tester and hydrometer. Best to buy batteries from a high turnover active store. I've seen batteries at a mom and pop service stations 4 years old. Not good, always check the "fresh" date.

    edit to say when batteries are sitting in the truck at zero or below, efficiency drops like a rock.
