Do a pull test on all wiring connections. That means where a wire goes into a Weidmuller or Wago connector, where a wire goes into a crimp lug, where a wire goes into an Anderson connector and where the wires go into the plug for the RoboRio power. If wire slips out, re-do the connection.

Check all screw/lug connections such as the battery cables on the battery and on your main breaker. The wire and lug should not be able to rotate relative to the battery or breaker. Tighten the screws if they move.

Use a flashlight and examine closely where the wires go into the small Weidmuller connectors (i.e. RoboRio power on your PDP). Look for stray strands on any wire that is not in the connector. These stray strands can touch adjacent wires which is always the opposite polarity on the PDP, VRM and PCM. If necessary, cut off the "crinkly" stripped ends, strip to the length shown in the Users Manual for the PDP, VRM and PCM, twist the exposed strands so they lay neatly together then re-insert the wire in the Wiedmuller connector carefully and ensuring that ALL the strands go in.
