Re: RoboRIO Red Power LED

The battery voltage was good so we swapped in a different roboRIO and it worked fine. The original roboRIO continues to show a red power LED with nothing else connected other than main power.

The places we expected to see 5V were:

- The 5V pin on the SPI connector
- The 5V pins on the analog input connector
- The 5V pins on the DIO connector
- The 5V/3.3V jumper next to the RSL jumper (inside the case)

All of these places showed somewhere around 30 or 40 mV instead of 5V.
