SEAL-LIP TYPE 5D1962 - Caterpillar

Engine: G3612 (S/N: 1YG)Introduction
This special instruction was written in order to give detailed instructions for the installation of the Caterpillar Ignition System. The following procedures should be read and understood before working on the engine.The CIS has been designed in order to operate in conjunction with the Caterpillar Timing Control Module on natural gas engines. The system was designed in order to replace the Altronic III magneto and the Altronic Interface Box. The new features that have been included are the advanced spark energy control, the primary diagnostics, the spark diagnostics, the self-diagnostics, the pickup diagnostics and the serial communications. The function of the Caterpillar Timing Control Module and the Spark Ignition Controller remains unchanged. No reprogramming of the system is required. The ignition system consists of two main parts: an engine mounted Ignition System and an optional customer interface control module. The ignition system consists of a Ignition Module, and a Hall effect sensor.Reference: For additional information, refer to the Special Instruction, REHS0190, "System Operation Testing And Adjusting For The Caterpillar Ignition System (CIS)" and to the wiring diagram (Vee Engines).
