The aircraft is still very new appearance. To measure the battery voltage is normal, only three electrodes of some dirty and surface has a slight concave. Three electrodes scrape dirt, failure is still power-on test machine. So after opening the lid motherboard pros and cons of cable outlet to stir up, took out the motherboard. Checked with a magnifying glass, but did not find signs of components Weld and damage. And then attach the battery to measure the three battery on the motherboard spring fillet voltage, discovered ② feet without voltage. This is obviously not normal, the general situation of ② The feet are the detection side of the battery voltage, the voltage should be between the battery positive or negative. So with the - branch table pen connected battery electrodes ②, another branch of the table T cell positive and negative. ② side, about equal to the voltage of the battery voltage and battery cathode ③ foot, so to determine the problem in the motherboard battery electrode spring (2) foot battery voltage detection feet.

This machine battery reed two fed shrink design. Without batteries, the whole pop-hand feel to the inside the top three spring stress to be small relative no-name models.
