Genesis strobe issue

I am a monolight noob so bear with me. I just took delivery on a Calumet Genesis 200 strobe. I shoot with a Canon 5D. Everything on the strobe seems to work perfectly except I can only make it fire with the test button. Hooked it up to the 5D with the sync cord but no dice. Put the 580 EX on the 5D, flash on manual, flash fired at photocell, tried all 4 photocell settings, still no go. Tried to fire it with the ST-E2 infrared unit. Nothing. Any help or ideas appreciated.

OK. Strange. Left the house for a couple of hours. Once I returned, I decided to try it again. Now it triggers with the flash via the photocell and also the sync cord. I can't imagine what I did differently. Works beautifully now. Checked under the couch for photo-knomes but found none but they're really sneaky.

Hi, Clif - Good to hear its resolved, but I didn't have any suggestions for you. Sounded like bad electronics so I'd definitely make note of it should it happen again. I just had a problem with one of mine and Calumet support was great at responding and replacing the part for me.

Considering that this was your first attempt ever with a monolight a chance of a user error is 99.999999999999999%
I would not worry much.

Thanks for the input. The problem seems to be recurring so likely it is a bad part and/or connection. I talked to Calumet support and they suggested exchanging it for a higher quality unit but I'll just take another unit of the same model which they said they would glady do. When it works, which is 99% of the time, the light is beautiful.
