What is the FAW Large Current Line & Bonding Strap Assembly

  • The FAW Large Current Line & Bonding Strap Assembly forms the critical high-amperage circulatory system within FAW commercial trucks. This robust network manages massive electrical loads (200A+), ensuring reliable power delivery to vital systems while establishing secure grounding paths to prevent electrical noise and component damage. Engineered for extreme conditions, it integrates heavy-gauge cables, fusible protection, and vibration-resistant hardware to withstand engine heat, road shock, and corrosion.
  • High-Current Power Distribution & Protection
  • Wire Assembly-Connected Battery & Wire Assembly-Battery Positive To Power Master Switch: Creates the primary artery carrying unfused battery power to the master switch for centralized system control.
  • Wire Assembly-Power to Chassis Fusible Link Box: Routes protected power from the master switch to the fusible link box, where high-capacity fuses safeguard against catastrophic shorts.
  • Wire Assembly-Motor Connected with Power Master: Delivers switched high-current supply to critical motors (starters, winches, PTO systems) with minimal voltage drop.
  • Wire Harness Assy-Preheater Power Wire to Chassis Fusible Link Box: Supplies fused power to engine preheater circuits via corrosion-resistant terminals.
  • Engine Grounding & Vibration Security
  • Bonding Strap Assembly-Engine To Battery Negative: A braided copper or tinned-copper strap providing a low-resistance ground path between the engine block and battery negative. This prevents “ground loops” that disrupt sensitive electronics (ECU, sensors) and ensures stable voltage reference.
  • Outside The Sawtooth Lock Washer: Installed under terminal nuts on bonding straps and power lugs. Its internal teeth bite into metal surfaces, resisting loosening from engine vibration that could cause dangerous arcing or voltage fluctuations.
  • Industrial-Grade Cable Management
  • Cable Ties & Buckle Type Plastic Tie Band (x2): Heavy-duty nylon ties secure cable bundles along chassis rails. Reinforced Buckle Type Plastic Tie Bands handle thicker power cables, preventing abrasion against sharp edges and maintaining clearance from exhaust components.
