Electronic Vernier Control EVR001 - Navistar Mack Engine Throttle Controller

This hard to find part includes the resistor pack for Mack and Navistar engine throttle control.

The EVR001 vernier control is hand operated for precise, variable engine speed adjustment on electronically controlled stationary engines, or from a remote operating position on mobile equipment. It uses a linear potentiometer to translate mechanical position to an electrical signal in order to control the engine from a remote location.
