CONSIGNES DE SECURITE L’utilisation de cette lampe stroboscopique requiert de travailler sous le capot avec le moteur en marche. C’est une situation potentiellement dangereuse et l’utilisateur doit prendre toutes les précautions nécessaires pour éviter les risques d’accident. Les consignes de sécurité suivantes doivent être observées en toutes circonstances: •...
l’allumage et des repères de calage sur le moteur qui permettent d’évaluer le calage à l’aide d’une lampe • Ne pas oublier que la basse tension présente aux bornes des circuits basse tension de la bobine d’allumage stroboscopique, ainsi que des dispositifs permettant d’effectuer les réglages du calage nécessaires. et dans les rupteurs peut aussi être source d’électrocution.
mort haut), lorsque les repères de calage sont PMH (point mort haut) ou BTDC (avant le point mort haut). Cela Le repère de calage sur l’organe mobile du moteur semble donc être stationnaire dans la position exacte qui impliquerait que le flash de la lampe intervient avant d’avoir reçu le signal de la bougie d’allumage. Il existe est la sienne au moment de l’allumage de la bougie d’allumage du cylindre No.
LECTURE INSTABLE: Si le repère mobile allumé n’est pas stable, mais qu’il varie de manière incontrôlée, B. TEST DE L’AVANCE A DEPRESSION cela indique que la pince à induction ne détecte pas de signal stable en provenance de la bougie d’allumage. •...
Pour vérifier les autres cylindres (2 et 3 sur les moteurs à quatre cylindres), un marquage précis de la poulie à 180° est nécessaire. Une erreur régulière (de plus de 2 à 3 degrés) dans le calage de l’allumage entre les cylindres indique un mauvais réglage ou l’usure de la came de rupteur, l’usure ou la torsion de l’arbre de commande d’allumeur ou une erreur significative dans le réglage des points.

Gunson Advance Xenon Timing Light 1. SAFETY PRECAUTION Using this timing light necessarily involves working under the bonnet while the engine is running. This is a potentially hazardous situation, and the user should take every precaution to avoid any possibility of injury. The following guidance should always be followed: •...
Gunson Advance Xenon Timing Light • Never ever attempt to use automotive diagnostic equipment intended for 12v applications on domestic AC mains 240V supplies. • Make all electrical connections with power off, so as to avoid the possibility of electrical sparks, which can ignite fuel vapour or inflammable battery gas emissions.
Gunson Advance Xenon Timing Light Such ignition systems are designed so that if the user sets the "static" timing correctly, then the automatic advance mechanisms will take over and ensure that the ignition timing correctly adjusts to other driving conditions.
Gunson Advance Xenon Timing Light higher RPM, for which the car manufacturer has provided data in the handbook, but has not provided timing marks on the fan belt pulley. For these jobs a simple non-advance timing light is not adequate, and the user needs advance timing light.
Gunson Advance Xenon Timing Light A Xenon discharge lamp of very high energy output is provided, combined with a lens which gives a wide beam of brilliant white light, enabling the timing marks to be readily seen even under conditions of high ambient light. Should the lamp ever need replacing, spares can be obtained from The Tool Connection Ltd RED and BLACK clips for connecting to the car battery.
Gunson Advance Xenon Timing Light 6) With the engine of the car switched off, make the connections to the car: • Connect the RED lead to the battery positive terminal (+), • Connect the BLACK lead to the battery negative terminal (-), •...
Gunson Advance Xenon Timing Light until the timing mark on the eccentric shaft pulley is in line with the timing indicator pin. • Tighten the locking nuts and recheck the timing • Repeat the above stop for setting the trailing side distributor timing with the...
Gunson Advance Xenon Timing Light The solution to these problems is to paint a TDC mark onto the fan belt pulley or flywheel (using white paint or typing correction fluid), or on the casing of the engine, using a protractor scale as a guide, and use this TDC mark as a reference in further timing measurement.
Gunson Advance Xenon Timing Light NB: Some distributors are adjustable for vacuum advance (examine the area around the vacuum advance or retard operating rod). C. TESTING VACUUM RETARD This feature may be fitted for emission control, and only operates at idle and during deceleration.
Gunson Advance Xenon Timing Light 8.
