How to figure out the camera shutter wiring
===================================
See diagram:
Wire two diodes, only tie black ring side together,
Now use labels to mark (A) terminal, (B) terminal <-- (A) and (B) can be swapped interchangeably
and also mark ( C) terminal where two black rings joined together.
On the camera shutter control cable side, recording down the colors (e.g., it has the Red-Black-Grey color-coded wires)
Use a regular Nikon auto-focus lens (in AF setting), turn camera ON, set control to "M", 1-second exp time is good.
Use a pen and pencil to create and write down various permutations.
>>>>>>>>>>>> Procedure 1 <<<<<<<<<<<<<<<
Try Grey (as the "Common") wire first, connect that wire to terminal ( C).
- now try Red wire to connect to terminal (A), do you hear the lens attempting to focus on some object?
### If yes, Red is the "FOCUS" wire, and Black is the "Snap" wire
(to verify, tie Red to (A), then tie Black to (B) the camera should take a shot
### if no (disconnect Red wire, still leave Grey wire connected to terminal ( C)
- now try Black wire to connect to terminal (A), do you hear the lens attempting to focus on some object?
### If yes, Black is the "FOCUS" wire, and Red is the "Snap" wire
(to verify, tie Black to (B), then tie Red to (A) the camera should take a shot
### if no, Grey wire is not the "Common" wire
{Repeat the above steps in procedure 1, except this time, assume Red is the "Common" wire, then figure out Black wire and Grey wire's function)
If this procedure fails, this leads to the last chance:
{Repeat the above steps in procedure 1, except this time, assume Black is the "Common" wire, then figure out Red wire and Grey wire's function)
If this procedure fails, something is terribly wrong.
Clear Skies!
