The E-Z-GO 36-Volt 4-Gauge Battery Cable Set on your cart is vital. These necessary wires are the thing that gets the voltage up to where it needs to be to make your buggy run. Let's jump down this rabbit hole for a minute to ensure the proper function of your vehicle. Getting this cabling incorrect is a prevalent mistake that causes costly repairs. Ones that are easily avoided.Your golf cart batteries are wired in series. That means that they are daisy-chained from the positive of one post to the negative of the next. The main positive cable is wired to your solenoid, and the main negative is wired to the controller. At those two points, you are not reading an individual battery but the entire 36-volt battery pack. When a single cable fails, depending on where it is in the pack, it can cause the overall voltage reading to drop. When this happens, you are looking at a loss of anywhere from one battery to the entire pack. Call Buggies Unlimited and get a set today so you can stay on the road longer.
