Angle grinder wiring ?

[sardine]

This Metabo grinder is different from it's wiring diagram , it has 3 wires to the capacitor and 2 white wires coming from the second stator winding, one has continuity with the stator one has no continuity with anything, white wires have male and female terminals , there is no spare negative terminal on the switch . How does it work if the negative isn't going back to the switch like usual ?

Why didn't you ask directly to me?
There should be 2 wires Wich have continuity to each other
Those two go in and out of the stator
One goes to the brush holder and one to the switch
Capacitor is connected in parallel between the wires Wich enters into the stator windings
The one which has no continuity should go to the capacitor as grounding to the stator core
Need more detailed pictures to give you the ok to connect this way
