That would be a 5 solenoid cart. Make sure all the slide micro's are clicking in the speed box and resistor coils are not broken ot touching. more then likely its a bad solenoid or two. Put the cart on jack stands and press the go pedal, you should here the first one, master solenoid click and cart should run, solenoids 2,3, 4 and 5 are like gears low speed to high. So i would say one or more of those inbetween solenoids is bad.
