The second set of 24v wires feeds the solenoid breakout (properly).

I'd suggest a systematic step-by-step isolation of the problem.
If it's repeatable in a timely manner.

Example given:

1. pull all the power breakers
2. pull the camera and radio power
3. pull the 24v connector

• Turn the system on, see if the 24v power light goes out
• if not:

1. Add in the power breakers

• Turn the system on, see if the 24v power light goes out
• if yes, further isolate the offending breaker
• if not:

1. Add the camera and radio

• Turn the system on, see if the 24v power light goes out
• if yes, further isolate which power causes the problem
• if not:

1. pull the two remaining cRIO modules
2. pull the solenoid power separately from the Breakout
3. Add the 24v power back for just the cRIO chassis

• Turn the system on, see if the 24v power light goes out
• if yes, probably remove the cRIO and do an internal cleaning, per NI directions. Retest.
• if still yes, pull the second set of 24v wires from the connector and retest.
• Check the module pins as well
• if not:

1. Add the Digital module

• Turn the system on, see if the 24v power light goes out
• if yes, test in the alternate digital module slot, as well to see if the problem follows the module.
• if not:

1. Add the unpowered solenoid module

• Turn the system on, see if the 24v power light goes out
• if yes, test in the alternate digital module slot, as well to see if the problem follows the module.
• if not:

1. Add the 24v solenoid Breakout power

• Turn the system on, see if the 24v power light goes out
• if not: (the gremlins have won)
