Narrative:

Departed fll international. Was given a heading to intercept the fll 9 departure, thndr transition, 16000 ft. Captain was flying and called course alive. As the course indicator moved toward the center, I began to turn and intercept while climbing. I glanced over at the first officer's course indicator and his was not moving. I brought it to his attention. We now did not know which instrument was correct. Both vors were tuned to the same frequency. I asked the first officer to confirm our position with departure, but instead he asked them if the VOR was working. I then said, 'I need to know our position to determine which instrument is correct to keep from getting too far off course during the departure phase.' he went back on the radio just as the 1000 ft altitude warning went off, so he didn't hear or see it. I was distraction also for the same reasons. The so called out altitude. We were at 16500 ft when I pushed the aircraft over and back to 16000 ft -- our assigned altitude. The cause of this was the same as so many others. We allowed ourselves to be distraction by a problem and were not flying the aircraft. I've been involved in numerous abnormal and emergency sits and never allowed this to happen before, but all it takes is one time. Another lesson learned!
