2008 keystone Montana slide out issues

[Yruss101us]

Okay so I have a 2008 Montana with four slides it has the one button slide control with the four knob manifold on my hydraulic pump system above the tank the hydraulic pump clicks and turns inside but does not work I'm baffled I've tried using a drill to turn it manually but still does not move my slides any suggestions? Thanks in advance

Welcome to the forum

Are all the knobs fully open?

If you are trying to use the cordless drill to turn the hyd pump and driver it to move the hydraulic slides NOTHING WILL EVER move if you don't manually open the ONE SINGLE HYDAC valve using an allen wrench on the end of that valve and opening it first.

The Hydac valve for the slide outs ( there is only one ) is NC ( normally closed ) via spring pressure

It opens electrically when you operate the slides using the switch.. SInce you aren't using the switch and trying to use the drill there is no 12 volts going to the coil on that Hydac valve to electrically open and allow fluid to flow.

If the motor doesn't run normally using the switch there is a simple TS step to perform to determine if the motor and dual polarity solenoid are good or bad..

This PDF will tell you how to check both...

Yes I've opened the screws on the manifold and then I've also tried one individually by their self each time all that's happening is the motor itself is spinning but when I try to use the switch there's a clicking sound from the solenoid unfortunately we're out camping so I don't have all the tools I need so I'm not able to check the actual voltage going to the solenoid but I am getting some sort of power because it arcs when I touch a ground wire to the positive
