Abstract

Cette invention concerne un système d'allumage avec indication de bon fonctionnement (HIIS), qui vérifie qu'un système d'allumage atteint un niveau établi de performance au niveau de l'éclateur (17) de l'allumeur, en détectant les variations du débit de courant du système au moyen d'une bobine de détection (68, 69, 70) située à la sortie de l'un des composants et potentiellement de plusieurs des composants. Ce système isole les défauts du système en identifiant le composant défaillant, réduisant ainsi les nécessités de dépannage, le matériel de test et l'utilisation de personnel et évitant la nécessité de fixer un dispositif de test qui pourrait masquer, falsifier, corriger temporairement ou modifier des caractéristiques du défaut.
