Definitely think some new leader may help.

Today I dismantled the moving parts in the cassette and cleaned all the dirt from them and smoothed them as much as possible and applied some WD40 very sparingly. The film is now able to travel much more easily and the camera appears to function correctly except for an unpleasant sound.

I’m not able to identify the cause of the sound but I’ve been able to video the camera in operation and you can hear the sound……http://m.youtube.com/watch?feature=plcp&v=FFA0REyJw_I

I’ve had the camera running from a 12v Lead Acid battery with limited success.

It powers the camera and it runs well but the film in the cassette isn’t advancing as it should. The drive for the take up spool is based on friction and is partly free to rotate because it must gradually get slower as the spool increases in radius as it takes up film.

The mechanism doesn’t work well as there is too much friction required to drag the film round the cassette and take it up on the take-up reel. The mechanism can’t overcome the friction so it doesn’t take up the film.

Very grateful for all of the responses. I’ve attempted to run the camera with a length of film leader and using a small rechargeable 9v battery, didn’t want to be too heavy handed and inadvertently blow anything. The film advances slowly – the camera appears to function as it should but it’s underpowered so I need a better battery than the one I’m using.

Tried turning the transport sprocket upside down but it’s not possible. The transport sprocket in the film cassette contacts with 2 terminals inside the camera case as it turns. What effect will it have on the camera should the sprocket not turn as it should? Will the speed of the film vary much depending on the amount of film that has been taken up, is this sprocket part of that design or will it be to send information to the footage indicator that would be displayed in the cockpit?

Still trying to work out the wiring but the assistance of a copy of the manual will be welcome help.

Any suggestions on cost effective film to purchase when I’m up and running.

The wiring diagram is a great help! Thank you.

Have you been successful getting yours to run? I rather tentatively tried to get mine going with a small battery – it will advance a few seconds and the battery runs out of power! I’ll have to try something more heavy duty. Any idea what sort of current it will handle? I’ve got the 12v version.

Heating element intact on mine also. All in all the whole camera is a very clever piece of kit.

Thanks For the response Phil,

The other thread talks about the variants of camera and to which aircraft they are fitted. I’m after specific information about how the camera operates and how to check it for correct function – in particular the inputs to the camera to activate it. For example, the camera can operate at different speeds depending on the gun fitted to the aircraft, is the camera manually adjusted or is it governed by a control unit of sorts?

Any advice appreciated
