Distributorless ignition adapter for diagnostic oscilloscopes
First Claim
1. A distributorless ignition adapter for diagnostic oscilloscopes, comprising:
- an interface box;
an oscilloscope connection cord having a first end connected to the interface box and a second end terminating in an oscilloscope plug;
several inductive pick ups 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;
the number of inductive pick ups corresponding in one to one relation with the number of ignition coils for a particular model of engine having a coil on plug ignition system; and
each of the several inductive pick ups is sufficiently flexible to wrap around an ignition coil.

Abstract
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.

4. A distributorless ignition adapter for diagnostic oscilloscopes, comprising:
-
an interface box having a plurality of receiving jacks;
an oscilloscope connection cord having a first end connected to the interface box and a second end terminating in an oscilloscope plug;
several inductive pick ups coupled with the interface box and adapted to sense passage of electrical current through ignition coils, sensed data relating to properties of the electrical current being transmitted to an oscilloscope via the interface box and the oscilloscope connection cord, each of the inductive pick ups being sufficiently flexible to wrap around an ignition coil, thereby enabling the inductive pick ups to be adapted to different sizes of ignition coil, each of the several inductive pick ups having a lead wire terminating in a pick up plug which is adapted to mate with one of the plurality of receiving jacks of the interface box, such that each of the several inductive pick ups is detachably secured to the interface box and a service technician is able to alter the number of inductive pick ups to correspond in one to one relation with the number of ignition coils for a particular model of engine having a coil on plug ignition system.
