V- generation on oscilloscope DSO138

00:40:01

Troubleshooting the DSO138 from JYE Tech as I'm not getting a trace. Measuring V- gives a positive value instead if -8.1V. 

As I haven't worked with this style of circuit before (inductors a-plenty) I thought I'd try simulating it to get a better understanding. The pulse comes from a microcontroller and the voltage divider gives feedback, so I haven't been able to simulate what's going on fully.
