EMCP3 Caterpillar

The original "Electronic Modular Control Panel 3" (EMCP 3) design utilized existing hardware. The Early Introduction Packages, shown in Illustrations 1 and 2, are still in use today. The latest EMCP 3, shown in Illustrations 3 and 4 uses the Global Design Package. Both versions of the EMCP 3 have some components, such as the "Start Aid Switch", that are optional. Some of the components, such as the speed potentiometer, are only found on certain engines. The information for the components can be found in the sections that contain the illustration for that specific component.
