There are seven recessed gold contacts on the bottom of the F3. Six are recessed about 0.5 mm, and the seventh is recessed about 2 mm. Is it supposed to be like that? The pin on the DCS winder has ample travel to make connection, but perhaps the "deep" contact is indicative of a problem with the camera. I thought I'd ask here before I dismantled the camera to check it out (I'm a bit of a klutz).
Thanks

Motor Drive contacts on F3/DCS?
Pete
If I'm holding the camera with the bottom facing up and the back of the camera facing me the contact at about 7:30 on a clock is recessed farther. I confirmed that on two F3 HP's. One with a digital back. The other with a film back, which it probably always had.
I guess that's good news?
I think you said the DSU had an intermittant display. I'm guessing that if the battery is totally dead, the power supply gets loaded so bad that the results are unpredictable on the entire DSU. If that's true, I'm not sure, then you may want to not have a dead battery in the unit.
The battery is the same as a hellapina of a lot of video cameras, as is the battery charger. I picked up three batteries recently on eBay for $0.99.
Good luck with the rig.

Keep your mirror up!
Thanks for checking. That's exactly how mine is, but it looked broken.If I'm holding the camera with the bottom facing up and the back of the camera facing me the contact at about 7:30 on a clock is recessed farther.
It was intermittent, but I fixed it by making sure the flexible PC was firmly inserted into the display connector. I got new batteries right away.I think you said the DSU had an intermittant display.

I can still take a shot once in a blue moon, but only immediately after I've switched on. I assume it's a thermal problem, but nothing seems to get too hot. I've checked all the DC to DC converters, but they seem OK.
Thanks for your help.
Pete

Fore more info on the seven contact points, you can take a look at the info on the excellent Photography in Malaysia website:
