The 7815 appears to be installed backwards. If so, it's likely been damaged.

So the problem is likely on the Output driver board? On the middle row of pins at 1 end the pin connects to an ic (U4) and at the other end the pin connects to a diode

There was a problem with the regulator. There may be no other problem.

It connects between the secondary ground and the heatsink (when the board is screwed down). There shouldn't be any voltage (AC or DC) on either end of it.
