Robert, the counter is automatically reset when you open the back.No amount of rewinding film will rewind counter.Counter should not advance when back open,the counter gear is disengaged.The counter wheel is returned by a spring similar to a watch main spring,that is tensioned on assembly.It is unusual for the A series counter to jamb completely. In the main the ones I have seen failed because the spring fractured,hence it will count but not zero. Now for the bad news,your problems may only just be starting.I have seen two instances where pieces of the broken spring completely destroyed the Delrin shutter gears.I am pretty sure that the spring was broken by the winder,when you operated it without film in camera.All the A series winders depend on the film reaching the last exposure to stall the winder motor,thus telling you to rewind film.If you operate without film you can wind the counter well over 38 exposures.How much will depend on how much tension was prewound onto the spring on assembly.Just like an over-wound watch spring,the spring breaks or pulls free.The very fact that you wound on through to 0 and the counter still works is another indicator of a spring problem.I sujjest that you should find out if you have any bits of spring loose inside camera.Winding by hand you might feel it start to jamb up,using the power winder will certainly wreck the camera. I have never seen any reference in Canon literature to REWINDING back to S.Winding On to S is important before using power winders,as trying to gain extra frames means that there is not enough film on take-up spool and the inertia imparted by the winder can cause the film to jamb. Sorry for bad news but it is easy,or not very costly,to remove top and just check that spring is not broken.If that is case then just continue using as is. Glenn |
