If your mercedes engine is equipped with an electronic ignition system, you may skip
this section because electronic ecm ignition systems have no distributor breaker points or condenser.


The ignition system, works by the opening and closing a switch in the ignition's primary
ecm circuit. This stops the primary current and develops secondary current in the ignition by induction. This induced secondary current is ultimately used to send a signal to the 1121534679 ecm to fire the spark plugs and to send out an injector pulse. While all components of the Mercedes auto computer system
are important and must be functioning properly for an efficiently running engine, the distributor breaker, or contact, points are perhaps the most vulnerable component in the engine computer system. The breaker points are located inside the distributor and are attached to the breaker plate by screws. Two wires are connected to the points. One is the ecm ground wire and the mercedes ecm is the ignitions primary other system. The breaker points are constructed of a low resistance metal, usually tungsten. Electrical current flows from the wire connection, through the movable arm of the points assembly, across the closed points to the stationary part of the assembly, and on to the ground to complete the ecm for the 1121534679 Mercedes
