Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing electrical component may initially manifest as intermittent issues, such as flickering lights or temporary loss of function. If ignored, these problems can become permanent, leading to complete failure of a specific system or circuit. This can result in operational downtime and potential damage to related electrical systems if not addressed promptly.

Installation Tip

Always disconnect the battery before working on any electrical component to prevent short circuits and personal injury. Ensure all connections are clean and securely fastened to maintain proper electrical conductivity.

Service Note

Inspect the associated wiring harness, connectors, and fuses for any signs of damage, corrosion, or loose connections.
