Should a Broken Automotive Wiring Harness Be Repaired or Replaced?

[CamillaLee]

If it's a normal wiring harness with no issues, it can simply be reconnected if broken. However, if the break affects normal wiring functionality, replacement is necessary. A damaged engine wiring harness can cause inaccurate signals, leading to vehicle startup failure. Below is relevant information: 1. Causes of Damage: Proximity to heat radiation sources accelerates harness aging. High-temperature gas leaks in the vicinity expose the harness to temperatures beyond material tolerance. A relatively enclosed environment with minimal air convection relies mainly on radiation for heat dissipation, resulting in slow cooling. 2. Four Major Benefits of Harness Maintenance: Reduces circuit impedance, enhancing system circuit efficiency. Features flame-retardant properties, improving vehicle high-temperature resistance. Exceptional permeability effectively repairs circuit cracks.
