Constant DAP-1522 Resets

That configuration is not legal and will not pass inspection so I wouldn't put too much time into debugging it.

The relevant rule is <R38-B>

B. The radio power feed must be connected via the 5V converter (model # TBJ12DK025Z) to the marked 12 Vdc supply terminals located at the end of the PD Board (i.e. the terminals located between the indicator LEDs, and not the main WAGO connectors along the sides of the PD Board). No other electrical load can be connected to these terminals (please see the 2011 Robot Power Distribution Diagram posted online at www.usfirst.org/frc/kitofparts for wiring information).

As described in the rule you must use the 12V-5V provided in the Kit of Parts and you must wire it to the 12V supply terminals on the end of the PDB. If you have trouble with that configuration, that is what I would look to troubleshoot.
