Claim Rejected. Corrosion on Electrical Component

A burnt or melted connector at a specific pin is a strong indicator of excessive current (Amps) flowing through that point. In electrical systems: • Current (Amps) flowing through a connection creates heat • The heat generated follows the principle of Joule heating • More current = exponentially more heat (since heat ∝ current²) So if a connector is melted: That pin has been carrying more current than it was designed for

Why the fuel pump causes this A fuel pump is essentially a small electric motor. Under normal conditions, it draws a steady, designed current. However, if something goes wrong internally: • Worn bearings • Seizing or tight rotation • Internal friction (armature issues, contamination, wear) Then: 1. The motor struggles to turn 2. Resistance to motion increases 3. The motor compensates by drawing higher current 4. That excessive current flows through the connector 5. The weakest point (often a pin/terminal) overheats 6. Result: burnt plastic + melted connector ________________________________________ Key point (simple explanation) You can explain it like this: “The connector didn’t cause the damage — it shows the damage. The fuel pump motor started failing internally, which made it draw too much current. That excessive current overheated the connector pin, causing it to burn and melt.” ________________________________________ Important technical clarification To push the point further (if needed): • A bad connection alone can cause heat, but typically: o It shows localized arcing or corrosion o Not sustained heavy melting unless current is already high • In your case: o A clean burn/melt at the pin strongly supports overcurrent, not just a loose connection

Bottom line ✔ Melted connector = symptom ✔ Root cause = overcurrent draw ✔ Overcurrent source = failing electric fuel pump motor Electrical component?
