Not quite right, the Crio when it sense battery is at 5.5 volts will inhibit all output. The power supplies will stop functioning at 4.5 volts.

Deploying code will not cause the power supply to malfunction. However, plugging into the Crio port can and often does disturb the power wiring. My first suggestion is to remove the Crio connector from the PD and turn the power on. If the 24 volt LED comes on, check the Crio power wiring for stray strands or mis-wiring.
