Issue with power distribution board

[Jon Stratis]

Hey all - we did our first power-on test of the competition robot today. After fixing some wrong wiring for a spike (I think someone on mechanical did it when they moved it) that was popping a breaker, everything seemed to work except the radio.

We pretty quickly figured out it wasn't getting any power. The 12V light on the PDB is NOT lit, and the Wago connector next to it where the leads from the radio plug into does not get power. Powering everything off, pulling the Wago connector out, and powering on gives the same results - no 12V LED and no power to the two pins. So, a few questions:

1. Does anyone know what the internals of the PDB look like? Is it possible we shorted the wire and have a blown fuse in there somewhere?
2. Is this something likely to be user-fixable (we have a fair amount of skill, talent, and experience available, we just haven't been able to take it apart yet)?

If anyone has any ideas, please post them. Right now, the plan is to show up a little early for the meeting and swap it out with our PDB from last year (which was on our practice robot and working great), but i'd like to salvage this one if possible - otherwise we'll have to buy another one to have a replacement if needed later.
