CONDENSER CONSTRUCTION:

The condenser is constructed of layers of aluminum foil, insulated from each other by layers of high dielectric insulating material. One layer of aluminum foil extends beyond the insulating material on one side, while the other layer of foil extends beyond the insulating material on the other side. The layers of aluminum foil and insulating material are then rolled into a tight cylinder and inserted into the condenser case. The layers of aluminum foil extending at one side will contact the bottom of the case and represents the ground terminal of the condenser. The other layer of foil will contact a disc which is connected to the insulated lead of the condenser.

Current does not flow through a good condenser. If it does, the layers of foil are touching or there is a hole in the insulating material. If either condition exists the condenser is defective and must be replaced.
