Thanks zero999, I will start looking in that direction for something had a feeling I had a decimal point in the wrong place
Yeah there are a few things dead on this board, diodes, caps, possibly the 3phase driver, 15v and 9v regulator .
Don't get me wrong I don't think it was all broke originally but I have been slowly killing it with every test and bodge. It has went bang at least 3 times now after testing.
But I am sure I can bring it back to life. Somehow....
Digging out the board from all this black potting compound has been a challenge in its self.
