Speed controller failure can happen in many forms. The electronic speed controller in your golf cart or electric vehicle is the most complicated component in the vehicle and is often considered the brain of the electrical system. Although a book could be written on all of the various failures, for the purpose of this article, we’ll stick to simply performance degradation over time and use.
When E-Z-GO introduced its RXV model golf cart in 2008, it was a drastic departure from the “norm”, in the fact that it has no mechanical wheel brakes. Rather than use traditional wheel brakes, E-Z-GO elected to go with the inherent regenerative braking available with AC, coupled with a disk style motor brake pad located on the end of the motor. We recently had an RXV golf cart in our shop with serious problems to this brake disk, which nearly resulted in a serious accident for the driver.
We get a multitude of questions about how to gain more power from an electric golf cart. As with many questions of this nature, there are several means to an end. Below, we will discuss how to increase your torque to gain more power from an electric golf cart, as well as define some basic terminology to help understand these concepts.
A golf cart motor speed sensor is, in simplest terms, a device which detects or reads the rpm of the motor and transmits this information to the speed controller to control various motor functions. A golf cart motor speed sensor can be mechanical, electrical, or magnetic based. We’ll discuss several different types, how they operate, why they are needed and symptoms when they fail.
We get lots of questions regarding battery terminal repair on electric golf carts. Often, the need to repair the terminal is due to a melted post, or other scenario that does not allow the power wires to be secured to the terminal. Rather than replace an otherwise good battery, we’ve gotten creative over the years and have learn how to easily handle this battery terminal repair.
Golf cart rentals are a staple of any dealers business and a “necessary evil” if you will. From the outside looking in, this would seem a profitable business segment because you make money from the rental of the cart and get the vehicle back to do it again. However, not all is as is seems in this business. Within this discussion, we’ll outline some of the pros and cons of the business, headaches, and the potential for damaged vehicles.
Golf cart fuel pump problems can often be caused by a clogged up pump due to debris and other foreign objects. We did another tutorial last month regarding golf cart fuel pump problems, but we had a special case in the shop a few days ago and thought it might be worth a follow-up. Below, we’ll discuss this case and fuel pump in further detail.
We often receive questions about checking golf cart charger diodes. We have prepared a great tutorial to explain what a diode is, what it does, how to test it, and replacement procedures. These procedures are relatively simple, but a multi-meter with the capability of testing continuity will be need for testing.
