I got the screwdriver and popped off the cover and removed the motor. Here's what it looks like.

Thank you, I really appreciate your help! Im still in the process of acquiring the right screw driver to gain access to the motor but Ill post pics as soon as I can. In the mean time here's a pic of the inside of the camera. I'm very new to this but I'm trying to get it to work with a D tap battery.

Thanks

So I've recently acquired an Arri 16BL for an upcoming short film I'm directing but am really not that knowledgeable or experienced in this format so I was hoping to get some help. I've been doing some research on how I'm gonna power this thing but there doesn't seem to be a lot of resources for this camera. I was planning on using a v mount battery and connecting it that way but have run into a problem. I've looked thru the original manual but am slightly concerned because the back of my Arri (where the battery port is supposed to be) is missing. I'm assuming the previous owner changed some things on it but again because I'm very new to this I'm at a standstill as to what to do. 

If anyone has any suggestions on how I should power this that would be greatly appreciated!

Thanks
