Default precedent shuts down at full throttle

OK here is the deal. I have a 2007 club car precedent PQ0730-785892 with new batteries and when you put the pedal all the way to the floor it shuts down.

here is the problems
throttle will go from 0% at rest, to 100% at about 3/4 throttle, to 0% past 3/4 throttle. when I put the hand held on the controller.

first issue I changed the controller, because the pre-charge resistor kept getting really hot. and it fixed that problem

next drive cart and runs great until full throttle. So I change the MCOR. same problem.

next change the speed sensor. Same problem

next change the pedal assembly. Same problem

next changed the controller again to a different one. Same problem.

checked all the wiring and verified voltage and ohms, everywhere it should be. Everything checks out okay.

Please please please can anybody help me.

Also forgot to mention throttle fault is always in fault code until pedal is 1/4 pressed and throttle percentage goes to 1% the goes back to fault after 100%

It does the erratic throttle like you describe.

You will need to modify the harness and add some resistors if you want to use that Controller.

Where does the harness need to be modified and what needs to be done?
