Narrative:

About 30 minutes after takeoff we got a right generator warning with right gen cont light. The captain ordered that I continue flying and talk to ATC and then started the APU and took the QRH. He read the name of the checklist and about that time; when the APU took over the associated bus; we had an auto pilot disconnect. I switched to hand flying and connected to another autopilot. After that distraction--which caused the captain to look up and then go back to the QRH--he went to the other checklist on that page--the one for generator drive disconnect--and started doing the items from that list. The moment he disconnected the generator drive he realized the mistake; but the generator was already disconnected. We continued with one [engine driven] generator and [the APU generator]. Our destination weather was clear. [We] landed with 13;600 pounds of fuel. The right gen light was on all the time until it was disconnected; so we definitely had a generator problem.there is one very important lesson to learn from this experience: always match the EICAS annunciation with the title of the checklist in the QRH to avoid unnecessary mistakes like this one.

Original NASA ASRS Text

Title: Following accessing the appropriate QRH in response to an EICAS R GEN warning and an illuminated R GEN CONT light; the Captain of a B767-300ER was distracted by a momentary autopilot disconnect and then performed the wrong QRH procedure found on the same page; the generator disconnect checklist. After realizing the error they elected to continue to destination operating with the left engine driven generator and the APU generator.
