Narrative:
We were departing white plains on our takeoff roll when we got a (generator) light, we aborted takeoff. By the time we started the abort it went out. We ran some checks and when it checked out ok we decided to depart. We departed with no problems. About 15 mins into the flight we got the generator light again and the generator dropped off line. We then ran the checklist as we started back to white plains. We also advised ATC we needed to dump fuel so we could make our landing weight. ATC okayed us to dump fuel so we did then landed at white plains with no problems. We called our office and advised the president of the company and other personnel.
