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.......................................................
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
It sounds like you have not wired it up correctly. I hope you have damaged anything in either the flash or the camera.
You need to connect the center pin on the flash hotshoe to the center pin of the camera hotshoe, and the ground connection of the flash hotshoe to the ground connection of the camera hotshoe.
Test fire the flash by jumping a wire from the center pin to the ground contact.
