Main function: 1. Check battery 2. Power function test 3. Check the starting capacity of the battery 4. Battery overload display Wiring method: Connect the red wire clip to the positive (+) pole of the battery and the black wire clip to the negative (-) pole of the battery.6 LED lights: Alternator Status Check: First Light (Red): Fault Second Light (Green): Good Third Light (Green): Complete Battery Status Check: First Light (Yellow): Middle Second Light (Red): Low Third Light (Green): OK Different LED display to show battery status: Display 1: All LEDs are off; test results: no charging voltage, discharged battery Display 2: “ON” LED flashing, other LED off; test results: charging voltage 4.6-11.2v, with the engine barely turned on, turn off all electrical equipment and charge the battery immediately. Display 3: ON LED on, faint flickering; Test results: charging voltage 11.2-11.6V, battery weakly charged, charged immediately.Display 4: Low LED on, middle LED flashing; Test results: charging voltage 11.6-12.2V, battery medium charged, better to be charged sooner. Display 5: Middle LED on; Test results: charging voltage 12.2 V, battery medium charged, better charged. Display 6: “Middle” LED on, “Full” LED flickering; Test results: Charging voltage 12.2-13.1 V, battery medium charged, better charged. Display 7: Full LED on, Good LED flickering; Test results: charging voltage 13.1-14V, good battery, full charge. Display 8: “Good” LED on; Test results: charging voltage 14V, good battery, full charge. Display 9: Good LED on, Fault LED flashing; Test results: charging voltage 14-16V, battery may be damaged, check motor and tester.Display 10: “Fault” LED on; Test results: charging voltage above 16V, defective battery.
