We have already started shorting out the various outputs just to make sure.
That is good news that there is some protection in the individual modules, but that still won't protect that fuse from shorts at the PDB.

If there is a short between the wires that power the VRM or the PCM (not the loads connected to these modules), will the 20 amp fuse trip? This would be the same as just shorting the output of the 20 amp fused output on the PDB, so I'm assuming it would.

I have a fear of these hard to diagnose intermittents shorts after this season. We played with multiple teams (at least 4 that I saw) whose PWM outputs would drop out because of an intermittent connection between the DIO power pins, which caused the DSC's 5V supply to go out.
