Did I burn out my electronics?

I've finally gotten my prusa i3 from Makerfarm.com assembled and wired, but I think I broke it. Like a big dummy, I turned the large driven gear on the extruder by hand about 1/4 turn while it was hooked up to the RAMPS 1.4 electronics. Without any power supply, the screen lit up for a moment and I realized that I probably shouldn't do that. Now I can't get my extruder to turn unless I plug it in on another place (for instance, the x axis motor plug-in).

Did I just burn out my stepper driver? Is there a way to test with a multimeter?

Was your extruder motor controller working prior to using the stepper as a generator?

I have no idea. I had just hooked everything up except the power when I did that.

Here's the url to the exact type of stepper drivers that I'm using:

Problem solved: hot end wasn't heated up (oh god, I'm such a noob). Now everything works.

i was gonna say lol I do that all the time, it isnt a problem
