Ok, here's an update:
1. Battery voltage with the car off is 12.6V
2. Battery voltage with the car running is 14.1V
3. If I remove only the B1 fuse with the car running, the gauge cluster goes dark and quiet
4. If I remove only the B10 fuse, the gauges stop working/twitching, all the indicator lights go out, and only the 3 lower screens remain lit with mileage, digital speedo, and clock, and the door chime works as well. No flashing indicator lights.
The flashing lights and twitching gauges seem to be related to the B1 fuse circuit. Thoughts?
Thanks!
