might be of some help.
You may not be able to trip the shutter with the Synchronar and have the shutter fire the flash bulb. Take a spent bulb and wire a flashlight bulb into its socket to use as a test bulb or connect the leads of an analog volt meter to the flash bulb socket's contacts to test the configuration. Digital volt meters do not respond quick enough to use.
The light bulb will light briefly or the volt meter will show a brief pulse when power is applied to the flash socket.
An electronic flash connected to the shutter flash sync with the sync set to M; aperture wide open; point shutter and flash at a white wall. While looking at the rear of the lens trip the shutter- the light from the flash will be falling off and the shutter blades will be visible in the lens opening.
