Mercedes Sprinter Positive Battery Cable Harness – OEM | NCV3 | #9064409813 (2010–2013)

A corroded, damaged, or undersized positive battery cable on a NCV3 Sprinter causes high-resistance voltage drop between the battery and starter and charging system — producing slow cranking, erratic charging voltage, and voltage-sensitive fault codes that can't be resolved until the cable is replaced. This is the OEM positive battery cable harness for NCV3 Sprinters, a direct replacement that restores a full-gauge, low-resistance power path from the battery to the starter, alternator, and main electrical distribution.

What This Part Does

The positive battery cable harness is the high-current electrical assembly that routes power from the battery positive terminal to the starter motor, alternator B+ terminal, fuse box, and jump-start terminal. It carries the full cranking current the starter motor draws on each start — typically 300–600 amps on a cold diesel start — as well as the continuous charging current the alternator produces during operation. The cable must maintain minimal resistance across its full length and at every connection point to ensure adequate voltage reaches the starter for reliable cranking and proper voltage is maintained throughout the charging circuit. When the cable jacket cracks and moisture enters, terminals corrode, or internal strands break from repeated flexing, resistance increases and the current-carrying capacity drops.

Common Symptoms of a Failing Battery Cable

• Slow or sluggish cranking despite a fully charged battery
• Voltage drop between the battery and starter confirmed by a voltage drop test
• Erratic charging voltage or battery warning light
• Electrical systems behaving abnormally after starting — indicating high-resistance charging circuit
• Visible corrosion, cracking, or physical damage to the cable body or terminals

When to Replace

Replace when voltage drop testing confirms excessive resistance in the positive cable circuit, or when physical damage or corrosion is found at the cable body or terminals. Always inspect and replace the negative cable and chassis ground straps at the same time.

NCV3 Specific — VIN Verification Required
