Stick, I know it's not the switch or the overload breaker. Both tested and in working order. I'm getting 110 to the controller circuit board, but only getting 30VAC at motor (with brushes removed). I got a feeling it's the circuit board, but not 100%. I found one at an after market parts website for 80 bucks. I'm tempted to try. The saw cost me around 200-250 at Lowes, around 5 or 6 years ago. So I know that's almost half the price of the saw. But I really REALLY like this saw! And Hitachi doesn't make scroll saws any longer.
