Power Shortage

    Ok so Ive been having problems for a while with my plow. Well they finally found a peice of metal near the pressure gauge and now it works perfectly..... but.....
    Now I seem to be having a power failuer. Last night during our latest snow storm I was out plowing for about 3 hours and then the plow became sluggish again. Now, however, everytime I moved the plow angle or height the headlights dimmed. After about 3-5 min after this sluggish motion the plow just lost all power and died.

    So I know its no longer a plow problem this only leaves the truck.

    Im trying to figure out is this a short problem, a battery problem, an alternator problem???
    Does anyone have any ideas or thoughts.

    Greatly Appreciated.......

    If you had been plowing for 3 hours before the problem occured.... sounds like the alternator isn't able to keep up with the heavy usage. I'd look into the output and maybe upgrade to a larger amp rated alt if there is one.

    Even if you have dual batteries, if the alt isn't able to keep up, it just takes a little longer to drain both batt. You sure the plow motor isn't drawing too many amps? I'm having a similar problem, but my HD alt. is producing 125 Amps at full load. My new Blizzard plow is drawing 140 Amps each time I move the joystick. The only remedy is a higher amp alt. They have a 165 amp unit available stock. There is also a company that makes a 200 amp unit.... but is like $300.00.

    THanks for the input. I hear ya.... I am trying to figure out whats the amps on my alternator. I was under the impression that these heavy duty diesels are supposed to have the 160 amp alternators with the dual batteries. Ill try to find out the amps on it. I dont mind buying a new alternator if thats really the problem. It beats shovelling lol.

    You can't run your strobes, rear lights, rotating lights, heater on high, radio and headlights all at the same time. You also have a dual electric salter too. I'm not sure if this is your problem but sometimis you have to choos what yuo need most. I don't run any extra power equipment unless it's needed. You also work in really small areas, which involves more blade movements, which takes more power. Shut everything off when in a safe place where it's not needed. I always turn strobes and flashers off when on the road because that is the best time for a recharge. JMO

    I don't know how old your plow is, but it sounds to me that your pump motor went bad. Check to see if you get power at the pump. If you do, check the amps it is pulling. i would bet your pump is pulling a ton of amps. 200-300 amps is normal under load. Anything over 300 means bad motor. I don't think you have a power supply problem at all.

    could this explain why it would work for 3 hours then have problems?

    I would definitely check the amps. Either the pump or motor is toast. The metal they found is a sign of something going wrong. The metal could be part of the pump and it was slowing eating itself up and then finally locked up. Either way, this would cause a huge amp draw. So check it before you send your wiring or pump motor into melt down.:rolleyes:
