I take a look and they were not backward. there are the schottky Diodes I used

I know it is for 3A but those were only for test, I got them from the school.

83

Those diode are OK
However I did just notice on your schematic that VCC is not connected to anything.
It should be connected to the same supply voltage that V+ on the MC33886 is connected to.

84

do u mean this VCC here

85

oh God, I just took a look, yes you are right, they are only connected with the Ground and not with Vcc

86

Check C6 to make sure it is not shorted or in backwards.

87

C6 is also not connected to VCC, when I do not use the wire then it´s not connecting, that´s the point

88

Yes but C6 is connected to the diodes, so make sure C6 is still good

89

okay so should I connect it to the Diodes from Vcc to C6 and than to the diodes

90

C6 really does not do anything but it can't hurt o have it connected to VCC

91

I will remove it when I do a new PCB, a correct one with every connection

93

by the way everything worked. I found the mistake 6 Weeks ago

94

Glad it worked!

I moved your topic to a more appropriate forum category @yt6161.

The Nano ESP32 category you chose is only used for discussions directly related to the Arduino Nano ESP32 board.

In the future, please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.

Thanks in advance for your cooperation.
