Engine: G399 (S/N: 49C1-UP)Introduction
This Special Instruction describes the installation of the following conversion arrangements for G399 Engines:
The 231-6569 Ignition Conversion Ar (Standard)
The 231-6572 Ignition Conversion Ar (Shielded) Note: The 231-6572 Ignition Conversion Ar (Shielded) meets requirements of the Canadian Standards Accociation (CSA) for hazardous environments.Both of the conversion arrangements include the 7C-0753 Magneto . The 7C-0753 Magneto replaces the former 7W-1479 Magneto that is no longer available.Note: If your engine is equipped with the two original 1W-3714 Magnetos , refer to Special Instruction, SEHS8478, "Installation Of 7W-1479 Magneto " in order to modify the engine for an ignition system that uses one magneto.The coils of the ignition transformers for the original magneto are not compatible with the 7C-0753 Magneto . For this reason, the conversion arrangements also include new ignition transformers and wiring.Do not perform any procedure in this Special Instruction until you read this information and you understand this information.Installation of the 231-6569 Ignition Conversion Ar (Standard)
