I've read many of the posts regarding this issue. My 2001 EZGO moves like a snail with fully charged batteries. I'm thinking that my problem is with the speed controller. Is there a way to check the controller to determine if this is the problem. There seems to be a couple of other components that would mimic the issue as well. What else can I check to possibly isolate the problem? The batteries are in good shape so I've eliminated them as the culprit. One other issue that has been going on for several years is when I switch from reverse to forward the cart will start and then stop momentarily. After releasing and depressing the accelerator pedal the cart performed just fine. This only happens occasionally. One last thing. Would a faulty speed controller cause my Powerwise charger not to work? The unit was working fine and out of the blue it quit. The charger unit has been rebuilt so I don't feel there is a problem with it. Thanks in advance for anyone who can give a little direction.
