1. Design Mistakes
The design phase is the crux of any electrical product outcome.
2. Manufacturing Mistakes
Wiring harnesses are machine-made. If the machine isn’t well maintained or the technician applies incorrect settings, wiring harness problems can result. Some of the most common manufacturing mistakes occur due to improper wire layout, poor connection to the harness chassis, or the complexity of the design.
3. Poor Quality Materials
When it comes to wiring harness problems, the old adage, you get what you pay for, couldn’t be truer. Budgets have a tendency to dictate purchasing decisions, and when they do, teams will often opt for cheap materials, such as copper alloy, instead of OEM-grade copper for critical components such as wiring and terminals.
