Hi everyone,
I’m currently near the end of an arduous Arri BL3 repair. I found and installed replacement belts—finally—only to discover that the camera has an electrical gremlin. The camera ticks over for about one frame before winding down and stopping. The camera is running off of a wall powered, 12V 10A power supply, so it’s got plenty of juice.
From what I understand, most DC motors function off of a “start” and “run” capacitor. This would lead me to believe that the camera is in need of a “run” capacitor to take it beyond an initial jolt of movement. Is this a misdiagnosis? Or if I’m correct has anyone dealt with this problem before and can point to the location of the electrical component in need of replacement?
Thanks so much, I’ll follow up with a short clip of the issue.
