Very odd Spike behavior

While doing a functionality check and debug we ran into an issue that has all of our students and mentors stumped.

We trigger a relay output in code, the state light turns green on the DSC, and the spike momentarily blips "forward", but then the state light on the spike just goes off. Not orange, not green, not red, just off, and there's no output from the spike.

The problem doesn't seem to follow any specific DSC output (tried 2), pwm cables (tried 2), or code. It sort of seems to follow spikes, namely old ones work (sometimes, but we only have 1) and new ones never work (tried 3).

Clear as mud I'm sure.

Anyone run into this type of issue before? Any advice on where to look next? We're really not used to debugging spike issues... they have always been dead-nuts-reliable for us in the past.
