Main function: 1. Check the battery 2. Power function test 3. Check the battery starting capacity 4. Battery overcharge display Wiring method: Connect the red wire clip to the positive (+) battery pole and the black wire clip to the negative (-) battery pole. 6 LED lights: Checking the condition of the alternator: First traffic light (red): Default Second Light (Green): Good Third Light (Green): Full Battery Status Check: First Light (Yellow): Middle Second Light (Red): Low Third traffic light (green): OK Different LED display to show battery status: Display 1: all LEDs off; test results: no charging voltage, battery discharged Display 2: "ON" LED flashing, other LED off; test results: charging voltage 4.6-11.2v, with the engine barely on, turn off all electrical equipment and charge the battery immediately. Display 3: "ON" LED on, "low" flickering; test results: charging voltage 11.2-11.6V, battery weakly charged, charged immediately. Display 4: “Low” LED on, “middle” LED flashing; Testing results: Charging voltage 11.6-12.2V, battery medium charged, better to be charged sooner. Display 5: “Middle” LED on; Test results: 12.2V charging voltage, battery medium, better charged. Display 6: "Middle" LED lit, "Full" LED flickering; Test results: Charging voltage 12.2-13.1V, battery medium charged, best 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: 14V charging voltage, good bat
