Cyclone 40 Design Rev A Board Mod

Looking at the top of the board with the PTO coil nearest you, note the positions of R7 and C18.

The left end of R7 (just below U1) must be grounded by adding a short jumper between it and the nearest ground, which is the left side of C18, directly beneath R2.

Do this on the bottom of the board with a piece of resistor lead, being careful to avoid contact with the pads of R27 and R2.
