The distributor is the nerve center of the mechanical ignition system that performs two specific functions. First, it induces the ignition coil to create a spark at a precise timing that is required. Second, it directs the spark to the proper cylinder. To do both jobs, the distributor greatly relies on the distributor rotor and the distributor cap. The rotor is the rotating arm located inside the cap, specifically on top of the distributor shaft. The ignition coil is connected to the rotor, which rotates inside the cap. The rotor spins past a series of contacts, particularly one contact per cylinder. As its metal tip passes each contact, a high voltage pulse is generated by the coil. This pulse arcs across the small gap between the rotor and the contact, and continue to travel down through the spark plug wire and to the spark plug at the correct cylinder.

During tune-up, one of the things that you usually replace is the distributor rotor. This is for the fact that it is constantly subjected to heat and the massive voltage from the ignition system that gradually takes toll on its life. It eventually wears out mainly because of the arcing. So if you see some early signs of wear, replace it at once before it cause serious complications.
