Re: Making sync cord for Nikon flash on Canon camera

Hi there! I am trying the same process with the same tutorial connecting an SB28 Nikon speedlight to a Canon Rebel Xti!
Last night when I first tested the modified cable, it would fire when the camera fired (plus it would randomly fire once or twice in a row without firing the camera). I hadn't setup any of the settings on the speedlight, so I'm not sure what it was set on.  
Going back to the project this morning, I am running into the flash not firing at all when I press the shutter button. The camera will fire the little on camera flash in the same mode, so it can't be the camera mode (Set in manual 200 iso in a dark room).

My brother is helping me and we tested the wires to make sure the connection is there. All appears to be OK.

I have the flash set up in the standy-by, manual mode (but have also cycled through other modes).

I've also tried:

✓ Changing to new batteries in the flash
✓ "Hard" resetting the flash
✓ Turning the flash and camera on in different orders

Other notes:
✓ The flash will successfully flash when I press the red test/flash button on the SB28 speedlight but ONLY if it isn't attached to the modified cord.
✓ When it is attached to the cord (even if the cord isn't attached to the camera) the flash will not fire when I press the test button
✓ If I connected the flash to the cable while the flash is ON, none of the buttons on the flash will work, including the power button
✓ If the camera is on and the flash is on and I connect the cord to the flash, the light flashes as soon as the connection is made
