Either wire will do just fine. But if you want to conform to the standard, com (aka, negative, ground, return, ...) is your black lead.

Yes, that com stands for common wire and the black is attached to that.. If, however, sometime you have a brown wire in your "mess", then the brown wire would be considered the COMMON wire

Black is always the common or negative connection on a testor and red is the positive.
If it is a multimeter, be sure you select the proper setting for AC or DC voltage

black -- "com" is "common" or ground for DC circuits.
Just do a search on "DC circuit common" and you'll find lots of sites.
