Hello and thank you for reading my post. I am starting the repair of an Excelvan Capacitor Meter M6013. The issue is that it works from the plug-in microusb but does not work from the batteries. It was working fine and all of a sudden it stopped working from the batteries. I plugged in the microusb cable and it works fine. Also, if I unplug the microusb cable with the batteries (brand new batteries, fully tested) it turns right off. I am going to open it up and see if the wires going from the batteries to the board have been broken. I will be posting pictures of the progress.

the best would be to identify the parts ... ive seen some m6013 teardown, but havent seen any dedicated parts for the battery
provide closer pictures of the components

I noticed the battery box wires are soldered with red wire as negative and black wire as positive going into the board. |O But it still gives Positive 3V going into the board as pictured.

I am guessing to start testing "Q6" on the board? Does anyone know what it is and how to test it?
