10076463Guidelines for Repairing or Replacing an Electrical Harness Use the guidelines in this bulletin to determine if a damaged electrical harness should be repaired or replaced. Refer to the wiring section in Group 54 of the applicable workshop manual for detailed wire repair instructions. Table 1 describes general guidelines for repairing or replacing a harness. There may be cases when more than one factor determines the course of action. For example, repairing a harness is recommended if shipping times for the replacement harness exceed one week. However, replacement may be the only option if damage to the harness is too extensive. NOTE: When a harness is repaired, the source of the damage must also be identified and repaired. Table 2 is a quick-reference for specific wire and terminal conditions. IMPORTANT: Damaged connectors and seals can be replaced without replacing the harness. A drag test should be performed to make sure that the terminal can retain proper tension to the mating terminal. Refer to "Terminal Drag Test" in this bulletin for instructions. Discolored wires or melted insulation should be replaced before any other repairs are performed on the harness.
