ASK THE MECHANIC

Q: Why does my electric Club Car Precedent periodically "surge" when I have the accelerator fully depressed?

A: There could be a few reasons for this. One reason could be that one or more batteries can be low, the motor speed sensor is cracked or is dirty, or the Motor Controller Output Regulator or MCOR is going bad. These two mentioned parts are relatively easy to replace. The speed sensor is located on the back of the motor and is secured by two small bolts and attached to the main wiring harness that leads to the controller. The MCOR requires you to remove the side rocker panels in order to remove the floor mat. Once that is done, you can remove the pedal assembly by removing the bolts holding it down to the floor. Underneath, attached to that assembly, is the MCOR secured by several torx bolts. The MCOR is the typical culprit of this issue though.

Q: I saw a good deal on a cart that was underwater. Can I rebuild it?

A: Sure, you can rebuild it, but just know that all electrical components would need to be replaced. This can be an overwhelming task, however, certainly doable. You would most likely need to replace the wiring harness, motor, controller, solenoid, and any sensors or switches, like the tow run switch, and speed sensors as well. You might even need to replace the rear end and steering box too. Just keep in mind that this can be a good project but be wary as the part costs can add up quickly! Freshwater would be more ideal as saltwater will get into every crevice and start rusting and corroding quickly.

Q: One of my batteries exploded! How did that happen?

A: There can be several reasons why this can happen. Let me start by saying that batteries emit a flammable and combustible fume known as hydrogen gas. Hydrogen gas is a by-product of batteries that occurs during a chemical reaction involving the water and sulfuric acid solution and lead plates. Signs that your golf cart batteries are overproducing hydrogen gas include but may not be limited to odor, corrosion, swelling and leaking. These battery conditions are attributed to poor quality chargers, clogged vent tubes, bad battery cables, wet battery tops, overcharging, overheating, and poor ventilation. A small spark of any kind can ignite this gas and combust. That is why it's very important to check the quality of your connections and routinely check your batteries. Do not touch any cables while charging or shortly after charging as the gases are at the highest levels. Always wear eye protection while working with batteries and NEVER smoke around your battery pack!
