A very common failure is to strip too little insulation off the wires into the PD. As a result, a few teams have had Digital Sidecars that looked like they were wired properly but, in fact, weren't getting power.

If the 5V LED on the Sidecar is lit but faint and the 6V and 12V LEDs are off, you probably need to remove some more insulation from the wires in the PD and reinstall the cables.

You could also have the wires swapped at the Sidecar's power input.

Make sure all 3 of the Sidecar's power LEDs are on.
