A defective condenser such as will cause contact trouble will cause serious missing of the ignition. Therefore, any of these troubles are comparatively easy to locate and should be immediately remedied.
These contacts should be so adjusted that when the fiber block B is on top of one of the lobes of the cam, the contacts are opened the thickness of the gauge on the distributor wrench. Adjust contacts by turning contact screw C, and lock nut N. The contacts should be dressed with fine emery cloth so that they meet squarely across the entire face.
The rotor distributes the high tension current from the center of the distributor to the proper cylinder. Care must be taken to see that the distributor head is properly located, otherwise the rotor brush will not be in contact with the terminal at the time the spark occurs.
The distributor head and rotor should be lubricated as described under the heading “[Lubrication].” The amount of ignition current required for different speeds is described under the heading “[Motoring the Generator].”

STORAGE BATTERY
Construction, Operation and Care
The modern storage battery does not produce or generate electrical force. It was designed to carry an extra supply of current in storage to operate lighting and starting systems, and in most cases the current required for ignition is drawn from this supply.

A storage battery is also called an accumulator, as it accumulates and retains a charge of electrical current for future use.
