Anyone has a working power-up for a yamaha XT125 dash ?

see pictures ;What max voltage is written on the capacitor? If 16V then you can powerup at the capacitor.

capa have 35V, so its 12V, also 5V stabilisation inside

GND , permanent 12V, i have.... but it needs 1 or 2 extra 12V supply !

better i ask here, before destroy something !

If this board is from your panel it is already burnt.

no, it will not work
All dashes need minimum 2 or 3 times 12V to light up, not "just" 12V !

yes i know, but i was ask which pinS need 12V

12V USUALLY GOTO THE BACK sides of the diodes mate, then beep out for the ground

nope....some circuits have "the back side" of diode(s) to the ground, just to protect against an inverse power-supply !
