Alternator condensers are seen mainly in older automobiles. Modern car radios are designed largely with a built-in shield against alternator-generated static. When a condenser is used, one of the leads connects to the alternator and one connects to ground. When a difference in voltage exists between the leads, a field is generated. Excess energy stores in the insulator, shielding the radio from the interference that would otherwise be discharged.
