I've updated the Pro8mm battery diagram to identify the mysterious component, that's a thermal sensor which kicks in at 55 degrees C. Since the original component has no markings, I've found an equivalent component (KDS 9700 55°C) Here's an article on using sensors on battery packs: http://www.semitec-usa.com/application/battery1.html The Pro8mm version only places the thermal sensor on the 3.6V supply. I'm not sure why it's not on the whole battery. If anyone knows why then I'd be interested to learn.

I just had a reply from Pro8mm and they have confirmed that my diagram is correct for the Pro8mm Classic camera. But if this is no value to Beaulieu 4008 users then please ignore it.

Agreed. As long as we use the pin numbering on the DIN plug and socket then there's no confusion. I meant they are reversed then looking at the "front" of the socket and plug. I've emailed Pro8mm for their pin configuration to see if it agrees with my diagram and if it differs from your findings. Steve says he used the R16 manual. So presumably the 4008 never had such a connector.

Hi Jean-Louis Two points: 1. The original photo at the start of this thread shows a 3 pin DIN socket. My wiring diagram shows a 3 pin DIN plug, so you would expect the pins to be reversed. However, maybe you've alread taken that into account. Which Beaulieu 4008 ZM model had one of these 3 pin DIN sockets fitted to the body? 2. Pro8mm of Hollywood modified my own Classic camera (an old 4008 ZM) and fitted this 3 pin DIN plug (or so I believed). The wiriing diagram I show is the correct one for this modification. I know this because I disassembeld the battery pack once it started to leak and traced all the wiring myself. So treat my diagram as correct for the Pro8mm Classic model (as it says on the diagram). I would be intrerested to contact Pro8mm to confirm this pin configuration, as I can't see why they should have reversed the pins for not good reason. When you say "Steve is right" then (to repeat my earlier question) which model of Beaulieu camera was fitted with this 3 pin DIN socket? I'm keen on getting the Beaulieu socket properly diagrammed too as there are no good diagrams on the web and the information above is totally confusing. thanks Eddy

sorry, I can't post my picture on this forum. Please find it here: http://neathfilmmakers.org/images/Pro8mmClassicBatteryPack.png In the diagram I have shown a brown component that connects two yellow wires. I haven't yet identified the component but I believe you can ignore it and just have a single yellow wire (effectively bypassing the component).

I have a Pro8mm Classic camera, which is a converted Beaulieu 4008 ZM II with a modified DIN 3pin socket fitted, powered by a battery pack. After investigating the wiring and construction of the pack I have devised the attached diagram. Hopefully this might help those who want to modify their own cameras or just want infor on how Pro8mm upgrade the cameras.
