Melex 412

Check batteries first! All tests (except pot output) depend upon testing with a good battery pack. Yours is a pretty simple machine. Lets get those batteries up and remove the resistor on the solenoid and tell me if it still passes current when it clicks.

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?

Thanks, TrollHole..it was the pot box...and I went to radio shack and bought a 10k potentiometer..Took the pot box apart & Found the 2 wires broken off.

have solder back on and it works!!!

Where do I fine wiring diagram for Melex 412 POT BOX with CURTIS SPEED COONTOL?

Use the diagram for the same year EZ-GO. ALL of the wiring is the same. Even the same controller.
