My 1999 EZGO golf cart got pretty wet in a recent tropical storm. Now it goes full speed only in reverse. In forward it only engages a a point just past the click with the microswitch. If you put the accelerator to the floor nothing happens. In forward it has one speed only if you can hold the pedal to the exact spot where it engages. Suggestions. I have cleaned terminals, spade connections, f&R cam.
