摘要： A distributorless ignition adapter for diagnostic oscilloscopes which an interface box, an oscilloscope connection cord and several inductive pick ups. The oscilloscope connection cord has a first end connected to the interface box and a second end terminating in an oscilloscope plug. The several inductive pick ups are connected to the interface box, whereby passage of electrical current through ignition coils is sensed and data relating to properties of the electrical current is transmitted to an oscilloscope via the interface box and the oscilloscope connection cord. Preferably, each of the several inductive pick ups is sufficiently flexible to wrap around an ignition coil. This enables the inductive pick ups to be adapted to different sizes of ignition coil. Preferably, each of the several inductive pick ups is detachably secured to the interface box. This enables a technician to alter the number of inductive pick ups to correspond with the number of ignition coils for a particular model of engine.
