Old Western Cable Plow Electric motor ???

    I have a 89 blazer with the old cable style hydraulics on it, last year I put a new electric motor, new cables, new pump and new wires on it. Last winter I also put a new interstate workhorse battery in. Now for some reason when I run the plow motor I can see the needle on the battery gauge drop.

    I tested the charging system, it's putting out 14.2 volts, I load tested the battery and after 15 seconds it hits the weak area on the load tester, then returns to 12.5 volts. When I hook it to the battery charger after that it only takes a couple minutes on any charger to say it's fully charged.

    I have the battery setup on a trickle charger when it's not plowing snow, since it's only being used around the farm.

    Could there be something wrong with the electric motor on the plow that's causing the heavy drain?

    Those motors do pull juice..Have you check the grounds on the truck. Or you might have to put a higher amp alt?
