Yes that is normal behaviour for floating ADC pins


Thank you,
From this I assume it's the volt sense on the Tesla inverter side.
I just didn't want to put it in another SDU without checking.
The 1.5v check did confirm this but I wanted to ask.
second hand part with no history is no fun ...

SDU board gets a voltage signal on pin 1 of the 24-pin gate drive connector. Whats the voltage on pin 1 with HV on?


Hi, first sorry if this is in the wrong area but it relates to the UDC.
I have 1.71v on my UDC with the logic V7 board connected to the inverter and 120v DC supply, with the logic ...
