    Your batteries aren't keeping up with the plow, or the pump motor is drawing too much amps which no battery will keep up with.

    Have the batteries tested as well as an amp draw test on the plow motor itself.

    Check all the plow cable connections for corrosion and tightness as well. A poor connection adds extra resistance to the circuit, which adds to amp draw.

    The fact that it takes 15 hours before it does it isn't that bad though. Some with have the same symptoms in only a couple hours of plowing.

    And of course bad batteries will do that as well so be sure to have them checked. Be sure to post back and share your findings.
