I plug my strobe into the hot shoe - or the PC terminal - and yet the flash doesn't flash. I went to B&H and bought new cables and it still won't work. (Of course, the cables have nothing to do with hooking it directly up to the PC terminal). I called Canon and they were, as usual, useless.

Am I doing something wrong? Shouldn't it simply flash which I click the camera?

The Hensels work fine when I test them but not when hooked up to the camera.

And to make matters worse, they don't flash when attached to my 10D either!

HELP!!!!
