<p>I know, old thread. My standard disclaimer, information never gets old.<br /> My New F-1, F1N, F-1 New was having this problem and it was driving me nuts. I found a tip on the Analog Photography Uses Group:</p>
<blockquote>
<p>Something else that helps if the magnet's sticky, is an abrasive to clean the contacts.<br />I use a small strip from one of our dollar bills*. Maybe around 2mm wide. put some alcohol on it,<br />put it between the contacts; hold the contacts together and withdraw the paper.</p>
</blockquote>
<p>I tried this and it works. To push the contacts together, you can use the winding lever to advance the mechanism, watching as you do this otherwise you can advance too far and the contacts will touch and move apart. I used some printer paper in lieu of the dollar bill but the effect is the same. Something between the contacts is preventing an electrical contact. I gingerly tried the "body slam" to confirm that something was wrong with the contacts before I found the method to clean the contacts. I'm not sure if I had oil or dirt, etc on my contacts but before I cleaned them the electronic shutter release wouldn't function on the "A" or "S" selector. Now both of them work.<br /> I've added some meta-tags to help search engines. Canon F-1, F1, F-1 New, F1N, New F-1, New F1, electromagnet, electromagnetic, magnetic, shutter, release, circuit, not working, broken, trip, close, click.</p>
