I charged the xhorse dolphin xp007 machine for a while night but it still shows level 1. Then shut down when power was cut off. Any solution?
Remove back side of the xp007 machine and remove handle.
You will see this yellow connector. Remove battery.
Test the battery output (24V) of the yellow connector with a multimeter to see if voltage is normal.
Then send the mainboard battery number and report the test result to us to check if need repair.
