Franklin's lightning bells. Easy Question. Please Help!!!

Homework Statement


Assume (for this part only) that the metal bell on the left was not grounded but connected to an insulator. Describe the changes as compared to question 4.
So the franklin lighting bells experiment has a bell on the right attached to a lightning rod, a metal ball on the left of it and then on the left of the ball is another metal bell that is attached to a metal pole leading to the ground.
I know that when the bell on the right is struck by lightning the negative charges are transfered to the bell and then attracts the positive charges from the ball which transfers negative charges to the ball that then move to the bell on the right and transfers negative charges to the bell on the right and the electrons flow to the ground.
So now with an insulator around the pole for the bell that leads to the ground what would happen. I believe that the bell would not gain any electrons and the ball would stay negatively charged. just wanted to check though.
