No, I said switch the stepper driver boards (the small PCB boards). Just take one from X, Y or Z (top right in the image above) and switch it out with the Ext (bottom right). Then if the extruder works, but not the X,Y or Z axis you took the driver board from, you know it is the stepper driver that was bad. These stepper boards are cheap (and easy) to replace.

On the Ultimaker Original board, you should be able to easily switch out two "stepper drivers" to check whether those are working (similar to how you checked the motor itself by putting it on another connector).
The stepper drivers are the small PCB boards on the right, directly next to the terminals for the steppers:
Note that the one for the extruder has a different orientation than the ones for the axes. This is correct; don't connect them in a different orientation.

Thanks ahoeben, in fack we tried switching the driver, but it seems the second extruder is not enabled for the Ultimaker Original, so we need to compile and reload Marlin with a new configuration.
Any chance you or somebody else knows the pin numbers for the second extruder on this board? I've been trying to find info but no luck.
