[Living a Fantasy]

I just bought a 2005 Yamaha Electric Cart which has new Trojan batteries. It goes maximum speed just under 20mph. My problem is that Yamaha has a braking system that slows it down when lifting my foot off the accelerator and/or going downhill. Was told that Yamaha has this built-in feature for their electric carts. The Yamaha Village's dealer tried to program it the best they could; but it hasn't helped much. They also said that disabling it may do harm to other components.

Has anyone on this forum experienced the above and what can you offer as suggestions so my Yamaha can run smooth and continuously?
