Grounding Practices
Properly ground the electrical systems for the generator, the engine, and the control systems. Proper grounding is necessary for optimum performance and reliability. Improper grounding will result in uncontrolled electrical circuit paths and in unreliable electrical circuit paths.Uncontrolled electrical circuit paths can result in damage to main bearings, to the surface of crankshaft journals, and to aluminum components. Uncontrolled electrical circuit paths can also cause electrical activity that may degrade the performance of the engine electronics.A block and traction alternator must be fitted with ground straps connecting those components to the locomotive frame.The ground strap for the alternator must be of a size that is adequate for carrying the full charging current of the alternator.
