What is the most prominent complaint people have about old cell phones? Not the old brick phones but maybe something a few models of the latest generation. The battery life seems to fall off to nothing. What this comes down to is age and a decrease in updates with age. Very similar in behavior is the motor on your caddie. However, you can keep it running like new when you replace parts like the 48-Volt Speed Sensor Retaining Ring when you start to have top-end issues. In brief, the magnet itself communicates the RPM of the motor to the controller. If the ring starts to get loose or go faulty, it can cause an inconsistent signal which locks you into low speed.This golf cart snap ring is not a hard part to replace. You are going to need a pair of snap ring or circle clip plyers to get this installed. Most people do not have this in their toolbox, but you can get it at the local hardware or auto parts store.
