Help for surf 1.2 PI

[esimplex]

Hello, I installed the kit surfing 1.2 PI and it worked right away, then I accidentally reversed the supply of 12 volts and I burned the controller 7805.
Now I replaced him but warm and outgoing I +3.3 volts instead of +5 volts. Which components may cause this increase in current consumption and which are to be replaced?
Thank you

Try to check 7660 ic. Its better put a reverse protection diode.
