[En-Nut-Discussion] No voltage at ADC VCC

[Daniel]

Hello,

I'm using an Ehternut 1.3H.
I cannot measure the voltage supply at the ADC Connector(Port F) between 
VCC(Pin 1 or Pin 3) and GND(Pin 4). But I get my 5 volts if I measure 
between the resistors R13(between VCC and Pin 1/3) and R15(between GND 
and Pin 4).

Do I have a failure in the hardware? And if there is a failure, can I 
use the ADC inputs furthermore?

Best regards.
Daniel
