The module has a sealed design to protect against non-uniform temperature gradients, humidity, corrosion and vibration.

Electronic design methodologies, technologies, and materials are selected to achieve minimal susceptibility to voltage spikes and glitches induced by environmental electromagnetic interference and severe duty environments.

The above module is shown in the stock position. Stock is all the way to the left (counter clockwise). Move the rotary switch to the Middle for the Low Position and to the far right for the High Position.

Agricultural Diesel Solutions is the best choice in aftermarket power modules for your tractor. They have listened to the needs of tractor owners, and have created a true solution to get the job done right with more power and less fuel. All electrical connections between circuit boards, switches, and wire harnesses are directly soldered. This eliminates potential corrosion-induced high-impedance connections, like opens, shorts, and partial or intermittent connections. Electronics are potted in a slow-cure epoxy compound. All selector switches which are not potted are of an inherently sealed design.
