Everything else checked out at the time - we had 12V going to the spikes, victors, jaguars, and everywhere else we had a breaker. The cRio was getting its 24V, and the camera output showed 5V. The other LED's were on. The problem was completely confined to the 12V output for the radio and the associated LED.

From what i know about the PDB, the breaker terminals are (more or less) straight connections to the battery, while the 12V output for the radio is regulated to remain at 12 V (it tracks to the battery above 12V, however it won't drop below until your battery gets really, really low).
