Kenworth Trucks W900B Jump Post Location & Safe Protocol

📍 Step 1: Terminal Location

Battery & Remote Jump Posts

Left-side under-cab step battery box or frame-rail remote jump studs.

⚠️ Step 2: ECU & Fuse Safety

IBS & Fusible Link Protection

Kenworth T680, T880, and W900 tractors running PACCAR MX-13 or Cummins X15/ISX15 engines have a Low Voltage Disconnect (LVD) that trips at 11.5V, requiring sustained high-amperage boosting to equalize all 4 Group 31 batteries before cranking.

⚡ Step 3: Charging Check

Alternator Voltage Test

Post-boost verification of 185A–320A Delco Remy 36SI / 40SI Brushless output (13.8V–14.8V on 12V; 27.6V–28.4V on 24V commercial).
