Re: Melex 412
You can check the pot box by pulling the blue and black wires off the controller and putting a multimeter to it and check ohms. your looking for something around 0 K ohms when the pedal isn't pressed and around 5 at full power. Another way is to go to radio shack and buy a 5k potentiometer and hook two wires up to it and the controller in place of the black and blue wires. And press the pedal and turn the pot up and see if you move. The potentiometer is only $3 FROM RADIO SHACK. If it is the problem you will have to buy a new one. If your not good with soldering as it has quite a few resisters and such I would recommend getting a whole new pot box.
Also is your solenoid clicking when you press the pedal?
