Battery Positive Cable 3703050LD291XZ for JAC N56 LD30H — OEM Positive Battery Assembly, Customs-Verified, IZUMI 3-Month Warranty

The Battery Positive Cable with OEM number 3703050LD291XZ is a direct-fit replacement for JAC N56 trucks (LD30H platform). This cable connects the positive battery terminal to the starter motor and main electrical distribution point, delivering high current for engine cranking and vehicle electrical loads.

The positive battery cable carries the heavy current required by the starter motor during cranking and supplies power to the vehicle's main electrical system. It must have sufficient wire gauge to minimize voltage drop under load. A corroded, loose, or damaged positive cable causes slow cranking, hard starting, dim lights, and potential electrical system failure.

• VerifiedCustoms Data Confirms Product Type: Export records for JAC LD30H N56 list 3703050LD291XZ as "POSITIVE BATTERY CABLE ASSEMBLY". This is the strongest available verification of the part's function.
• VerifiedPlatform Confirmed: Customs records specify LD30H N56 as the vehicle model.
• VerifiedChinese Parts Catalog Lists as Battery Cable: One Chinese source lists 3703050LD291XZ as "电瓶线(负极)" (battery cable) — note the negative designation conflicts with customs data.
• VerifiedBrand & Warranty: IZUMI aftermarket available; 3-month warranty offered.
• VerifiedPackaging & Lead Time: Neutral box, color box, or custom branded packaging; delivery 15–20 days after payment; small orders accepted.
• CautionProduct Name Conflict — Critical: IZUMI multi-language pages label this part as "Water Separator/Oil Assembly", which is clearly incorrect. Customs data and the product photo (battery clamp + eyelet terminal) confirm this is a battery cable. The IZUMI listing appears to have a product name error.
• CautionPositive vs. Negative Conflict: Customs data says "POSITIVE BATTERY CABLE ASSEMBLY", while one Chinese catalog lists it as "电瓶线(负极)". The product photo shows a standard battery terminal clamp suitable for either side, but the customs record is the more authoritative source. Confirm polarity with the seller before ordering.
• CautionTechnical Data Gap: Cable length, wire gauge (AWG/mm²), terminal hole diameter, and current rating are not disclosed. Measure the original cable if precise matching is critical.

• Slow engine cranking or clicking starter
• Dim headlights or interior lights, especially at idle
• Electrical accessories behaving erratically
• Visible corrosion, fraying, or broken strands at terminals
• Loose battery clamp or terminal connection
• Voltage drop across the cable (measured with a multimeter under load)

1. Disconnect the negative battery terminal first.
2. Disconnect the old positive cable from the battery positive terminal and the starter/electrical distribution point.
3. Inspect the terminals and connection points for corrosion or damage. Clean as necessary.
4. Compare the new cable's length, terminal size, and wire gauge against the original.
5. Install the new cable: connect the starter/electrical end first, then the battery positive terminal.
6. Apply dielectric grease to terminals to prevent corrosion.
7. Torque battery terminal clamp to OEM specification (confirm in manual).
8. Reconnect the negative battery terminal last.
9. Test: measure voltage drop across the cable under load (cranking) — should be minimal.

• Inspect battery terminals and cable connections at every oil change or battery service.
• Clean corrosion and apply protective grease as needed.
• Replace cable if insulation is cracked, terminals are corroded beyond cleaning, or voltage drop is excessive.
