Looking at the picture again....one spring tang is sitting very high above the center pin, and quite likely fouling on fork?
If you look at spring in relaxed state in the service sheet here

you will get an idea how much tension there should be, and how the fork must be free to rock around the centering pin to operate the ratchet pawls

One working red spot ammeter ? I decided to leave dial face as it is, as I intend to leave some age on the bike, and use it.

Hmm.....seems like that spring is very weak/streched, as they are quite difficult to get on usually, and have tendency to try and "twist off" the centre boss as you assemble them.
I would fit a new one....but, it doesn't really explain why you are missing second gear, as its purpose is simply to return pedal to centre :-\
Time for an expert, or at least somebody who has more experience of this box to comment?? ......mine went together with no problem, apart from what I have explained.

I dont understand how the centering spring can be slack on pin :-\
You have got the  centering spring ends "overlapped" on the pin I presume?....can be it of a swine to get right, while keeping the center loop on the short center boss. ???
I held centering mechanism in vice, pulled the spring into overlap position on peg with a pair of grips, and then assembled into outer case, holding in place using a bolt and washer in the internal thread in shaft, which I presume is for this purpose.
