TECHNICAL CHECK
Fuse, Connector, Wiring and Ground Connections
Electrical faults can be caused by a loose connector or poor ground rather than an expensive module. Visual inspection and measurement should be used together.
What is reviewed?
- Correct fuse rating and fuse-holder condition
- Connector corrosion, looseness and heat marks
- Wire insulation damage or chafing
- Ground-point tightness and contact quality
- Safety of aftermarket wiring
Model-specific limit: A fault must not be hidden by installing a higher-rated fuse; the manufacturer-specified fuse rating is retained.
