As I said- lesson from experience- don't count on emergency roadside or
campside assistance to rescue you if your slide won't move. They might
not be familiar with schwintek operation.
Or your board may be toast or you might have a bad/inoperable motor.
The video below will help if your board is getting an error or high current
from a motor but the board and motors are still able to run.
Here is a Lippert video showing how to override the board and force it
to run the motors when you push the slide extend/retract button.
If the board is toast but the motors are still good I've been told by the
warranty guy at my rig's factory it's possible to power the motors with a
battery from a portable drill or your trailer battery. Of course you need to know
which wires going to the motor you need to put the voltage on.
I don't know that.
My plan is to override the board IF it will run the motors.
If the board won't/can't run the motors then I plan to disengage the motor
from the drive shaft and push the slide either in or out as needed.
There are several videos showing how to take out the screw and then
lift up on the motor which disconnects it from the drive shaft.
The motor acts as a slide brake so you have to do this or you can't push
the slide.
As shown in the video you need to measure and cut a couple of prop sticks
and keep them in your rig. That way you can hold the slide in with
the motors disengaged. You don't want the slide to slide out on your way
home or to the dealer.
