✅ How to Fix — Step by Step

  • Step 1:Load test battery
  • Step 2:Test alternator output
  • Step 3:Clean battery terminals
  • Step 4:Check charging circuit resistance
💡 Pro Tip: Load test the battery and check charging voltage at idle and at 2000 RPM before replacing any modules — an inexpensive battery or alternator issue is a far more common cause than a wiring fault.
