Hi guys,
I had a short circuit on my LisaM V2 and now in the GCS
the battery voltage is contantly 18.4V. Even if I only connect the AP
with the USB cable.
What happend?
Due to a crash the GND wire
of the spektrum receiver [UART1/5, left pin] got contact with the metal
arm. Additionally made the screw of the motor a contact with the coil
wire of the motor... The shielding of the spektrum GND-wire was gone...

How is the LisaM connected:
I use the following wiring but only with the primary spektrum receiver. (11.1V battery):

The
AP still works fine (flights are ok), but I get a constant 18.4 V
battery value in GCS (and messages) when it's connected to the battery
or to the USB.
Is the ADC maybe damaged? How can I test this / use a different ADC input?
Any idea?
Thanks in advance.
