Originally posted by Peter Marsland Presumably this solenoid is damaged beyond use. (Again, no option to post photo or manage attachments. I'll post the pic when I work out how to do it.) Is there any point in trying to solder to the metal plate on the same side where the pin has just disappeared, the bottom side in the photo?
I can't see details well enough but I guess one top pin broke off.
Although
THIS PHOTO shows a SLR
* and not a DSLR Japan-Solenoid, you can see the copper-wire of the coil connected to the side-pin!
If you measure the impedance of ca. 30ohms across that pin to the other, then you solder carefully your cable to this pin!
It is possible. Because I solder the
old fashioned way I can "drop" the hot melted solder very quick and precise onto a small spot.
*not recommended as explained in detail

Addition:
What kind of soldering-iron did you use?
If the plastic melted from this correct DSLR solenoid as you described it via PM there must have been too much heat.
Either wrong soldering-iron (worst = butan)
or having touched the pin for much to long time!
