## NHTSA's summary

A failed or insufficient grounding system can lead to wiring and component failures, reduced efficiency, anddowntime. To help avoid these risks, it is essential to ensure system integrity by following repair instructionsand properly torquing all connection points. Proper grounding and bonding complete the electrical circuit andprovides a safe way for excess electricity to dissipate.
