I have a brand new hydraulic pump for a dump truck... when I connect the positive wire and the negative wire to the motor the pump spins without any pressing of the buttons on the remote... is it possible this brand new pump has a bad solenoid allowing the current to flow unrestricted...I have tried every which way to wire this thing...the manual is of little help

I think you might give us a little more info...Like what make and model pump that your working with. 
More likely that the person in China throwing these together at a rate of knots has just wired it wrong, or the contacts in the switch are stuck. There's not a lot in them, so if you have some basic skills, you should be able to sort it, with the help of NIW or others. Thinking about it, there will be basic circuits of them on the net if these are what you are talking about.
