Additionally, I'm always getting connectivity across the V+ and M+ terminals.

This sounds like a symptom of the following:

I encourage all teams to inspect their wiring often and regularly! I even mess up sometimes when hooking up lots of Jaguars... Always double check!
Metal shaving can also be the culprit, like others have stated. Never drill, cut, file, or modify metal while the electronics are on the robot or unprotected. Be sure to clean the robot before driving it because metal shavings like to release themselves into electronics as soon as the robot starts moving.
