At the Power Plant.

First of all, what do you mean by "second generator"? If you mean the generator in the Rocket hideout in Mahogany, then there is no second generator! All you have to do is kill all of the Electrode! Lance even tells you that!
he's on the gold bridge. if not then check the gym
You must get the generator part from the Cerulean Gym and give it back the Powerstation.
It is in the Cerulean Gym in the air thing on the left side. Hope i helped!¡
You get that part in the gym leaders building in the rubber tube.This is in Cerulean City
you have to solve the problem with the generator and get it from the team rocket member who is probably Russian
