Can I test it by removing it and applying +-12VDC?

Thanks,

You need a special stepper motor driver tool. I haven't actually tried it out, but I do have the driver tool and three spare motors, if you're interested I could sell you the tool or some spare motors. Also have a spare valvetronic module.
