Have 4 Canon A-1. Same issue. use a new battery (6v) When set to Bulb. Press the release button first curtain moved mirror up. Loss the button no second curtain moving(releasing) . short the mg3. the second curtain can be moved(releasing). and when I press the battery checking button can be moved(releasing). and switch the double exposure switch can be moved(releasing). and remove the battery out(power off). Those actions mean lower battery volt or power off I think.
I doubt the release button(SW) has a problem. But when using a low volt battery (5.3v). above issue disappear. so it looks not the release SW issues.
How to fix it?
