I came up with this to fix a RIELLO oil boiler control box again it turned out to be a electrolytic capacitor a few pennines ,new box was £80+.
Found a 7812 reg which I have now fitted and its giving me +11.82 volts, I connected it directly to the mains and the +5v and -12v are still good checked with scope nice and clean.
But the +12v is still low ?
