Problem:
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?
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.
