    I have a 8' mm1 with a insta-act system, 3 wire connection, 4 port module in the truck. since I bought the plow a few years ago it never worked correctly. it operates but VERY slowly, when I raise the plow it sounds like it wants to die, the motor and pump is very loud, motor gets really hot. I replaced the motor, took the pump off cleaned it as well as all the cartridges, put fresh fluid in and nothing. breathers fine everything else is fine, im lost. if any help would be appreciated as this is my spare plow and my main plow broke down a few times already.

    my other question is would the old powerpack system work with my 3 wire 4 port module setup?
