    No, What fluid are you running in the plow?
    Change it all to MEYER BRAND FLUID ! not napa, not ATF fluid only meyer.
    Had the same problem and struggled for two years....lesson learned.

    Now could also be a few other things, but first is first....

    This is common for a truck with a smaller alt. Could be fluid, but keep in mind the plow is pulling close to 300 amps which is HUGE

    Clean every electrical connection, make sure the plow is wired directly to the battery. both the power and the GROUND.

    both batteries test just fine. its not like one battery is half dead. it has as many cca's as the other battery. thats why i tested it, too see if it needed replaced, which it doesnt.

    plow is wired directly to the battery.

    Some drop is normal and virtually unpreventable. What is more important is that it comes back quickly when you release the control function.

    To get the maximum benefit from multiple battery's tied together they should be not only the same exact brand and spec but just as important also as close as possible to the same age thus reducing one from fighting the other to stabilize charge voltage between them.

    It's also a wise idea to do an AMP draw test on the pump motor to check both it's health and the health of the related wiring and connections. Should be done as preventative maintenance before the start of the seasons every year.

    you are lucky to have one the few Meyer dealers left in your area (I`m south of Milwaukee), once Meyer demanded all it`s parts dealers stock Meyer plows the people who were the Meyer distributor in my area (Monroe Truck) kissed Meyer goodbye so all thats available is the generic blue fluid....but it`s still $8 a quart.
