Maybe you also have dodgy capacitor.
Try swapping the connections on the big blue capacitors. So swap the black and purple wires from the right side cap to the left side and put the ones that were on the left onto the right.
You may already know that these caps are polarized - black wire must go to negative and purple wire to positive (which is marked on the top of the cap).
Try testing the voltages again(DC) once the wires are swapped and let us know result.
Just switched the wires over on the big blue capacitors and still getting similar 0.03 readings on the purple and black legs of the Bridge Rectifier. What's happening there?
Cheers!
Adam.
