Why do I have set the time and voltage, but after installing the power line, the battery has insufficient power? Why does it run out of power again after replacing the battery ?

1. Check whether the red yellow black (ACC/B+/ ground wires of the fuse are connected to the fuse holder correctly. Please refer to the fuse instructions in the installation guide. Connecting the red wire ACC to the fuse that continues to supply power after the engine is turned off or connecting it with the yellow wire B+ will make it impossible to judge ON/OFF through ACC , and it will cause continuous power supply after the engine is turned off until the battery is exhausted and the power is cut off. This is an incorrect connection method. Please change the correct connection method immediately.

2. Please make sure that the vehicle is not often driven. If the vehicle is turned off for a long time, the vehicle's electronic devices will continue to consume power. If the vehicle is left idle for a long time, the battery may be low and the vehicle may not be able to start.
