A friend of mine has a DeWalt 788 scroll saw. He said it quit working and determined that the control board was the issue. He tried to repair it himself. it did not work so he asked me to look at it. I need a diagram which shows the wiring connections on the board and where they come from (switch, pot, motor etc...). I have tried to find a wiring schematic on line but have had little success. I need help. Michael
