Re: no voltage across PWM pins on roboRIO

If there is an issue with the voltage rails providing power to the robot, the roboRIO should be reporting it via the power LED and on the DS power tab. Look of the short within the robot wiring, look at the base of the roboRIO pins, and if it persists when nothing is plugged in, the short may be within the case.

The power tab should go red whenever something interesting related to power has happened. Clicking on it will tell you some info about which type of power issue you have.

Since we are most likely talking about some debris inside of the roboRIO causing a short. Let me throw in a friendly reminder not to sprinkle your electronics with metal shavings or small pieces of wire. Get in the habit of covering electronics and or using a vacuum whoever you are drilling/filing/sawing or otherwise turning large pieces of aluminum into smaller ones.

If you believe that your roboRIO may have this issue, let the mentor/coach know, or if at an event, get a CSA to assist. NI support is there for issues like this, so get in contact with them.
