The integrated motorcycle starter generator control unit test instrument as described in claim 2, wherein the amplification and filtering circuit and the battery discharge test circuit are respectively connected to a battery test connection port, and the negative battery and positive battery of the motorcycle lead-acid battery are respectively clamped and connected to the negative battery clamp and positive battery clamp of the battery test special connection clamp wire, and the clamp connector provided for the battery test special connection clamp wire is connected to the battery test connection port, and the programmable microcontroller is used to control the battery test connection port. The processor is operated by the keyboard, and the motorcycle lead-acid battery test is selected. The motorcycle lead-acid battery relative battery discharge test circuit is started to discharge repeatedly for a short time, and after being processed by the amplification and filtering circuits, it returns to the multi-channel analog-to-digital converter to convert and collect digital signals, analyze and evaluate the quality of the collected signals, and present the evaluation results on the display screen. The motorcycle charging system voltage detection function is selected by the keyboard, and the motorcycle engine is started according to the prompts on the display screen. The locomotive power generation system operates, generating current to recharge the locomotive lead-acid battery, and then continuously measures the voltage of the negative and positive electrodes of the locomotive lead-acid battery, and displays the three sets of instantaneous voltages collected on the display screen: current, maximum and minimum. The display screen prompts that when the locomotive engine is running, the maximum and minimum values of the power generation recharge voltage should be within a reasonable range, indicating a normal locomotive power generation recharge circuit. The voltage range is automatically processed according to the program input into the programmable microprocessor. When the voltage of the motorcycle lead-acid battery is the voltage during normal operation, the display screen will change color to show it. If the voltage of the motorcycle lead-acid battery is higher than the voltage within the reasonable range, the display screen will change color to show the highest voltage value collected. If the voltage of the motorcycle lead-acid battery is lower than the voltage within the reasonable range, the display screen will change color to show the lowest voltage value collected. And through the keyboard operation, select the motorcycle startup detection function, and according to the screen display , prompting the start of the motorcycle engine. At this time, the negative and positive voltages of the motorcycle lead-acid battery will be continuously measured and collected at the moment of starting. The programmable microprocessor freezes the instantaneous minimum starting voltage and displays it on the display screen. The display prompts that the instantaneous minimum starting voltage should be within a reasonable range, which is a normal motorcycle starting circuit. The program input into the programmable microprocessor automatically processes the voltage range judgment, and the real-time voltage of the motorcycle lead-acid battery will be displayed on the display screen. If the voltage value is lower than the reasonable range, the display screen will change color to show the lowest voltage value collected from the motorcycle lead-acid battery. You can understand the status of the motorcycle starting system by simply watching the voltage color change on the display screen. In addition, through keyboard operation, select the motorcycle maximum load voltage detection function, and start the motorcycle engine according to the screen prompts on the display screen to operate the motorcycle power generation system, generate current to recharge the motorcycle lead-acid battery, and then prompt to turn on all the electrical systems of the motorcycle to reach the maximum power load. The negative and positive voltages of the lead-acid battery of the motorcycle are continuously measured and displayed on the screen: the current, maximum and minimum voltages collected instantly; the screen prompts that when the motorcycle engine is running and under the maximum power load, the maximum and minimum values of the motorcycle generator recharge voltage should be within a reasonable range, indicating a normal motorcycle generator recharge circuit; the program input into the programmable microprocessor automatically processes the voltage range judgment, and the voltage of the lead-acid battery of the motorcycle is the voltage during normal operation. If the voltage of the motorcycle lead-acid battery is higher than the reasonable range, the display screen will change color to display the highest voltage value collected from the motorcycle lead-acid battery. If the voltage of the motorcycle lead-acid battery is lower than the reasonable range, the display screen will change color to display the lowest voltage value collected from the motorcycle lead-acid battery. You only need to watch the color change of the voltage on the display screen to understand the maximum power load status of the motorcycle generator recharging the motorcycle lead-acid battery system.
