I was working with a Panavised Arri SR3 (24v) and whenever I would turn the camera power on, my lcd on my battery would show empty within a few seconds? I tried both of my cables that were made by Fred (which have worked properly on other cameras) and it would happen every time. Pannavision said that they did not change any of the power input/connections on the SR3, so what gives?
Any ideas? Has this happened to any of you before?
Luckily I was able to fly with the onboard Arri battery, which actually ads a positive amount of weight to the light camera, so that there wasn't any down time/stress.

P.S. when the shoot is over I will be taking my rig to Panavision and try to have them isolate the problem. I wanted to know if this has happened to anyone else.

That looks like a short-circuit!, very serious of course.

It could have something to do with the way the video-assist is grounded to the camera. This is because the video always works on 12 volts, so if they have made the "0" volts or ground on the wrong side of the battery, this could make the problem

I've seen something similar once with a arri 3, where, the moment the video was connected to the power (all coming from 1 battery) the camera began to run wild!
A different setup of course, but for sure something needs to be rewired in the camera!

The same thing happened to me last year with a SR3 from Panavision Hollywood. It turned out that the camera had a big problem. We couldn't make it work with any battery. Luckily we had two bodies for the episode. It turned out to be one of the accessory plugs on the New York side of the camera. It was putting voltage into the chassis of the camera. The only bad thing that didn't happen was smoke. We couldn't figure it out under the gun.

I doubt that it's your rig.
