Battery indicator shows empty immediately when powering on Arri SR3 camera despite properly functioning cables
22 years old. Gear and prices may have changed since.
What the thread found
- A camera that drains the battery indicator immediately upon power-on despite working cables may have a short circuit or grounding problem
- Video assist systems operating at 12 volts can cause excessive power drain if the ground reference is incorrectly connected relative to the battery polarity
- An accessory plug on the camera chassis can create an internal short if it accidentally connects voltage to the camera frame instead of through proper circuit paths
- When multiple external power cables work correctly on other cameras but fail on one specific camera body, the fault likely lies in that camera's internal wiring or components rather than in the cables themselves
Depends on
- The original poster did not complete their investigation at Panavision
- Discussion involves anecdotal reports from different camera bodies and configurations rather than systematic testing
- The exact cause was not definitively identified in this thread
