Is the same without back attached? I know you can not fire without back and film in it in single exposure mode - but just to rule out back problem. Did you test with body only, nothing attached (no back, lens, finder even focusing screen? I tested it just now and with nothing attached to the body
shutter lock OFF (9 o'clock position while looking from the front of the camera) , multiple exposure in OFF vertical position - i can not fire shutter (which is normal bc no hack with film in it was attached) but can fully depress it
Shutter lock OFF, multiple exposure in ON horizontal position - i can fire shutter
Have you tried using a cable release to rule out a problem with the shutter button? That would at least take one thing off the list of possibilities.
I had a problem with the multiple exposure lever a few years ago that gave me fits during an event, but it was one of those "suddenly started working again" things and never happened again. What I think I remember doing is something you've probably already tried. Wind on with the multiple lever forward, but don't shoot. Flip the lever back and then shoot. Then wind on normally and see if it works.
I have tried the cable release and the situation is the same.
I will try your suggestion with "playing" with the multiple exposure release though as I haven't tried that yet.
Thank you for your suggestions.
If after everything you find you need to send it for repair, Frank Marshman at Camera Wiz has a great reputation. Jimmy Koh at Koh's Camera was the guy I went to, but he has retired from Bronica repair. I have not used Frank but his reputation is very good, and Jimmy recommends him.
Yes, there is a interlock pin at the lower right side of the film back that protrudes from the magazine into the body, and it is what allows the shutter to be released when the magazine has been advanced to a new frame (unless the multiexposure lever is actuated on the body).

With a battery in the body, there should be a red wink from the red led at the lower right of the viewfinder (below the flash ready indicator), which happens when the shutter closes. Failure of the LED to blink normally indicates a dead battery. However, I once had purchased a used back whose interlock pin intruded into the body too far, causing the mirror to not rise all the way, thereby preventing the shutter from firing -- so although the mirror went up the shutter never fired and the red LED never blinked, and the magazine could be advanced to the next frame as if the shutter had properly fired! I had to send the magazine in to Bronica service to have the interlock pin adjusted (the body worked fine with my backs that I had purchased new).
