Just an FYI to anyone interested...we had this exact scenario happen today.
Radio went out, tracked it down to a blown fuse in the PDP, grabbed another one and happened again.
Disconnected the PCM from the PDP, and the radio from the VRM and powered up. Checked all relevant voltages and let it sit for a bit. Added the router and re-measured voltages and waited some.
Wired the PCM back in (without compressor), and measured and sit a while.

Added compressor back and checked and waited.
Then, as soon as the compressor was enabled the PDP fuse blew.

We are wiring in a spike, and it looks like we manually have to monitor the pressure switch in software now and enable and disable the compressor.

Not entirely sure why this happened now, but It seems like a bad idea to trust a game to that fusing arrangement.
