Not the right increments.
The Big yellow light will also flash incorrectly if wired incorrectly while connected to the proper RSL pins on the Digital Sidecar.


The big light m ust copy the special flash sequences of the tiny RSL on the Sidecar. There are special flashes for no code, Disabled, Autonomous, Teleop modes. If the flashes don't match exactly, then it's wired incorrectly.

I haven't seen Sidecars with only a bad RSL and nothing else broken before, but new things crop up for me all the time, so I keep an open mind about it.
It could be a ribbon cable bad connection, or a short inside the Sidecar from metal dust and debris.
You could try opening up the non-working Sidecars and cleaning them out.
