Engine News SEBD9316, 1 December 2002, "A New Ignition Transformer Group And A New Spark Plug Are Used". Disregard this article. Refer to the following article.

Description of Change: A new ignition transformer group and a new spark plug are used in the gas engine ignition on these engines. The new components will provide improved performance from the ignition system because of increased output voltage.

Adaptable To: The new 232-6350 Ignition Transformer Gp, 199-9011 Ignition Transformer Gp and the new 284-8313 Spark Plug (Multitorch) must be used together as replacements for the former 162-1419 Ignition Transformer Gp and the 146-2589 Spark Plug in the gas engine ignition on these engines. The former ignition transformer group is cancelled.

Note: The new 232-6350 Ignition Transformer Gp or the 199-9011 Ignition Transformer Gp can not be used with the 146-2589 Spark Plug. The former 162-1419 Ignition Transformer Gp can not be used with the new 284-8313 Spark Plug (Multitorch).

Note: All of the cylinders in an engine must use the new 232-6350 Ignition Transformer Gp or the 199-9011 Ignition Transformer Gp and the new 284-8313 Spark Plug (Multitorch) or all of the cylinder must use the former 162-1419 Ignition Transformer Gp and the 146-2589 Spark Plug. Do not mix the new components and the former components together in the same engine.
