The EB-191 course is a logical continuation of the EB-190. However EB-191 can be approached independently. The EB-191 course does however require a basic understanding of AC, DC and semi-conductor circuits. EB-191 requires a separate engine simulator, which connects through a ribbon cable to the EB-191 board. The engine simulator includes a DC motor (simulating the engine) which drive a three phase AC generator, which simulates the alternator.

The unit also includes a printed circuit board containing the components used for the simulation of two different triggering methods of electronic ignition systems: inductive pick up coil and Hall effect switch.

The module contains experimental circuits with which the student performs a number of conceptual experiments at various levels of difficulty. Manual or computer driver faultfinding exercises and testing provide valuable experience in the training and diagnosis of faults. Students are required to do only a minimal amount of wiring so training time is maximised. The module also ensures that students use their time more efficiently. The boards comes also equipped with "black boxes" containing components used in the fault-finding and practice modes, components which should not be visually identified by the trainee.
