Grounding Practices
Proper grounding is necessary for optimum engine performance and reliability. Improper grounding will result in uncontrolled electrical circuit paths and in unreliable electrical circuit paths.Uncontrolled electrical circuit paths can cause electrical activity that may degrade the engine electronics and communications.For the starting motor, do not attach the battery negative terminal to the engine block.Use a ground strap in order to ground the case of all control panels to the engine block.Ground the engine block with a ground strap. Connect this ground strap to the ground plane.Use a separate ground strap in order to ground the battery negative terminal for the control system to the ground plane.Ensure that all grounds are secure and free of corrosion.
