My wife is about to kill me. We have an '03 36V electric EZ-Go for her excursions around the property.
It's developed a "no climb" problem. With the throttle down, the cart goes about 1/4 speed on flats, and won't climb a 2% grade.
It's accompanied by a near-silent gentle vibration. Close listening discovers that the motor is running full-speed, but the wheels aren't.
I took off both rear hubs and inspected the splines. I've seen them go on EZ-Gos before. But they were fine, and that problem is usually accompanied by a fairly loud growling noise.
The motor input/diff-case is a unitized, sealed affair, and I cannot find any drawings for it -- electric cart, not gas; found the gas diagrams.
There _may_ be a belt inside the case, or a clutch to prevent overloads. This feels just like a slipping friction element. But I have to pull the whole rear axle assembly and both axles from the case to do that inspection -- ain't a small job. So I'm looking for hints first before I shoulder into that job.
On-line help is scant except for one site that is down right now.
Has anyone here seen this problem specifically on an electric EZ-Go?
