I recently bought a new Carberry (http://www.carberry.it/index.php) for Raspberry Pi B 2/3, together with its Carbian OS and installed it on a Raspberry Pi3/ModelB.
However, It shuts down few seconds after I connect the Carberry board to the 12V DC power supplier of the Lab Machine. My Carberry is not connected to an OBD port, it is only connected to the +12V red and GND black wires on Carberry connector pins 1 and 2 with the DC power supplier. No other pin is connected.
Did anyone here face the same problem and managed a solution to this problem ?
