4.4 controller D7

For the 4.4 controller, diode D7 is marked as "not fitted", but I mounted the diode. Does it have a disadvantage?

I would have to check my notes on that board, from memory it may be a reverse polarity protection diode. If you've fitted it and everything is working, then I would leave alone

It is a 5V Zener diode.

Ok, that was added to attempt to limit the voltage to prevent over voltage conditions. If everything is working, leave as it is.
