Default MCOR or Solenoid?

I have a 2003, 48v, club car. I have replaced all six batteries with new batteries, less than a month ago. I have tested all batteries individually and also done a load test. Batteries are good. All wires are tight and clean. I have a rocker F/R switch on the cart. Here lies the problem I am having. I have charged the car for no less then 8 hours, in tow mode. I put the key in and turn to on position, put the car in reverse, buzzer sounds but, car moves very, very slow. I put the car in forward and same thing, car moves very, very slow, even slower than when it is in reverse, even with the accelerator fully depressed. Any suggestions, can it be the MCOR or Solenod, or both or neither. Please help.

Sounds like a speed sensor problem. I assume your cart is an IQ, if so see the first Sticky and see if your car passes that test.

I have done the speed sensor test on the golf cart, and it passed. I did however notice that when I press down on the accelerator pedal, I hear no clicking at all. Prior to the car running extremely slow, I could hear clicking. Any other suggestions?

Make sure that the rod going into the MCOR is not to loose.

The only way to really test it is with a programmer.It is your speed switch,it took the place of the V-glide switch on the older club cars. It is bolted to the frame on the pass. side of the cart.

Ok, I check and the rod going to the MCOR is not loose. Any other suggestions, like I said I don't hear the clicking noise like I used to when I press on the accelerator when the car is on.
