Default Ezgo Marathon Throttle problems

When I push the gas pedal down all the way the cart doesn't move, but if I push the pedal halfway it will drive but at half throttle and if I try to push the pedal any farther, it turns off. What could be the issue?

Pot box (throttle) defective or out of adjustment

How can I test if its broken? and can it be repaired or do I need to by a whole new pot box?

Unplug the small black and white wires from the controller and measure between them with an Ohmmeter.
Should be about Zero Ohms with pedal up and about 5,000 Ohms with pedal down.
Push pedal slowly and the Ohms should climb smoothly.

Might just need some adjustment.

I just tested it, it climbs smoothly as i push the pedal and with the pedal up its at zero ohms and with it all the way down it's it at 7000 ohms. Im sorry I have never worked on the pedal assembly so does that mean its out of adjustment or does it mean it needs to be replaced?

0-5k is the correct reading, 7000 is over range. Dial it back to 5500 max and it should run just fine.
Find the adjustment screw at the pivot point of the arm.
