I have removed a stepper motor from a DVD drive which looks like the following: http://forums.parallax.com/attachment.php?attachmentid=102789&d=1373845076
As seen, there are 4 pins in a rectangular arrangement and the problem is that I currently do not have access to a multimeter therefore, cannot check for continuity within the coils to determine which pairs related to which coil.
Within the shown arrangement, is there a "rule of thumb" or an educated guess for determining which pair of pins relate to each coil? I know that in a linear setup where 4 pins are all one beneath another, the "rule of thumb" is that the top two pins are for one coil and the bottom two for the other, is there a similar rule for these???
Also, would I damage anything if I accidentally connected this up wrong? I mean if I connected the coil backwards or mismatched wires between the two coils?
