Re: RoboRIO Red Power LED
The red LED is in agreement with what you're seeing (5V output is low). 5V goes to a lot of places, including the MXP. Have you checked each of these places to ensure you don't have a short?
One more thing to try is removing the cover and moving the power selector jumper from 5V to 3.3V to see if the condition clears. If it does, then the 5V supply itself is probably the problem. If it does not clear, then you have a short somewhere among the 5V outputs.
