Entire Instrument Cluster Flashing - Gauges Spastic

[jdlmodelt]

If there is a voltage regulator resident on the cluster, it could drop out like you are seeing with the flashing when it is going bad or when it is not getting adequate voltage input. It does seem strange that your B1 voltage fluctuates as much as it does. The flashing could also be a voltage regulator dropping out to protect itself from a short somewhere. Troubleshooting can be a major pain! You said this all started after replacing the battery?

No, I replaced the battery going on a year ago with zero issues. This cropped up out of the blue during a Sunday drive.
