Cerbo GX Main Board Wiring diagram

Have a Cerbo GX that was connected with the +/_ reversed and popped the Varistor. Want to try and replace the varistor but need to know the spec of the varistor

Has anyone repaired a GX that was damaged with a revered polarity connection?
Also, Does anyone know where I could get the cerbo GX PC board Wiring diagram to see the spec of the Varistor.

I don’t believe any of that is public info.
Victron gear isn’t self-repairable.
There is a good chance you have cooked something else as well, and this isn’t typically covered by warranty.
