duplicate post in technique

Well i just got 2 420 ex's and when i mount them (one at a time) 1 of them flashes a red light on the 50 and the other one does'nt. They are mounted on a rebel xti with a 15-85 and 75-300 and there is no change when the focal length is changed. Did i get a bad unit (ebay) or am i doing something wrong. When the unit is off the camera it still flashes the 50, but if i select slave it goes to 24 and the other stays not flashing anything. Batteries have been changed.

The problem has been solved sorry
