How to Fix a Golf Cart That Won’t Accelerate
The best way to fix a golf that won’t accelerate is to readjust the battery cable, check all connections and replace the solenoid.
When your golf cart does not accelerate, the one thing you need to keep in mind is that while it is an automobile, it is not a regular vehicle like your car. Therefore, the methods you use to get your car started are not the ones you can use to get your golf cart moving.
There are two types of speed controllers – a drive control system and a precision drive system. While new-age golf carts feature a precision drive system, older models consist of a drive control system. These are the devices that are responsible for regulating the speed or the acceleration of the golf cart.
When the speed controller malfunctions or does not work properly, the cart will move but with several breaks in between. The golf cart will not be able to move at a steady or constant speed and that is one of the first warning signs of a problem with the speed controller of the vehicle.
Here are a few things you can do to fix the issues associated with your speed controller.
Flip the switch
The speed controllers in most golf carts feature a maintenance switch that one needs to flip before fixing any issue connected with it. Even if you have bought the golf cart recently, you should not have any trouble locating the switch. The switch can be found under the seat of the vehicle. A quick look at the manual will help you trace it easily. You will have to flip the switch and set it to tow-maintenance mode.
Readjust the battery cable
You will find a black-colored wire closer to the battery. This is the negative battery cable. You need to get it unplugged before starting your work to repair the speed controller. Once it has been disconnected, you should get the cover of the speed controller removed and the negative cable reconnected with the battery.
Check the connections
Check the wires carefully and see if all of them are connected properly. At times, something as trivial as loose wiring can cause the speed controller to malfunction. You have to ensure that all the wires are plugged in properly and tightly.
You will also need to check the condition of the wires carefully. If you observe wear and tear or corrosion in any of the wires, get it replaced quickly. You can get a fair idea about the voltage of the battery by colligating the negative and positive ends of the battery.
Get the solenoid tested
A solenoid is a switch that enables the flow of power from the battery to the different parts of the vehicle. If you encounter a problem with the solenoid of your golf cart, then you must know that it could be because of a faulty speed controller. To check the condition of your vehicle’s solenoid, you will be required to take a reading of the voltage and check if it is the same as the reading from the battery.
Power output of the speed controller
The last step involves taking a reading of the power output of the speed controller. For this, you will be required to link the positive probe to the B+ terminal and the negative probe to the M terminal. If the reading indicates that there is no voltage, the only option would be to get the speed controller replaced. If there is an issue with the motor, you might have to check whether the directional switch is functioning properly or not.
How to slow down a golf cart?
If you wish to have control over the speed of your golf cart, you have to ensure that the speed controller is in good condition. Apart from ensuring that the vehicle runs fast, the speed controller also helps in slowing it down.
When a golf cart slows down intermittently, the reason behind it is usually a weak battery.
A weak battery will not last for a long time even if it’s charged to its full capacity. When the battery becomes too weak, you have to replace it. However, there are a few things you can do before getting the batteries replaced.
Batteries usually go weak when lead sulfate accumulates on the surface of the battery plates. Most of the lead-acid batteries do not outlive their shelf life as lead sulfate crystals form on them. A vehicle not being used for several days at a stretch could also lead to weak batteries.
Sulfate build-up usually occurs on deep cycle batteries as they are used for a very long period before being charged. An excessive amount of heat also contributes to sulfate build up.
This problem can be solved by Battery Life Saver or BLS electronic desulfator. It helps in getting rid of the large number of lead sulfate crystals that build up on the surface by dissolving them.
The BLS transmits a particular electrical wave across the battery. It is directed towards the lead sulfate crystals, converting them back into sulfuric acid and lead. This activity undertaken by the BLS helps the battery to be restored to its normal condition and enables the battery to draw the electric charge.
An important thing to remember is that the batteries that you use for your car should never be used in your golf cart.
Why EZGO gas golf cart won’t accelerate?
The EZGO gas golf cart is known to be one of the most sturdy and durable golf carts out there. If it does not accelerate at some point in time, there is a possibility of some damage to its solenoid. The solenoid can be defined as the primary or the most basic electrical switch present in the EZGO gas golf cart. Its main function is to enable the flow of electricity from the battery into the motor.
When you press the gas pedal and hear a sound that resembles a tap, you must know that the solenoid has been activated. The golf cart will not function if the transfer of electric current is disrupted.
Current gets disrupted when the solenoid gets worn out or damaged. When you press the pedal, the solenoid gets activated and compounded into a metallic contact plate. With time, the pressure exerted during this process leads to the formation of small electric arcs on the surface of the plates. The resistance created by these arcs creates an obstruction for the current flowing through the solenoid.
This problem can be avoided by checking the contact plate regularly and getting it replaced whenever you see any signs of wear and tear on it. If you use your EZGO gas golf cart very frequently, you will be required to replace the contact plate sooner than later.
Why EZGO PDS won’t accelerate?
EZGO PDS was launched in the market around two decades back. Since then, this model has seen a steady ascent in its popularity and many structural improvements in its design.
You can identify a PDS model by taking a closer look at the black-colored plastic cover that surrounds the solenoid and the controller.
If you see some diagnostic codes mentioned on the cover, you know that it is indeed a PDS system. EZGO PDS models are also known to feature a programmable controller and a motor.
Why EZGO RXV won’t accelerate?
If you understand the importance of a motherboard on a computer, you can compare that to the role a speed controller plays in the functioning of a golf cart. Even if there is a minor issue with the speed controller, it might result in your EZGO RXV not moving forward.
When you find your EZGO RXV not accelerating, you can try a particular technique that might prove to be helpful. Pull up the brake pedal using your foot. Once you do this, the brake should release and the cart will start accelerating once again.
The speed controller works towards regulating the speed of the golf cart. There are instances when the speed controller fails but the vehicle will still start and move ahead. But, as it runs a few miles, it will start malfunctioning.
In such a situation, even when you try pressing the gas pedal with a lot of force, it will not move ahead. If it does move ahead the speed of acceleration will be uneven or patchy.
There are several reasons behind a speed controller malfunction. The most common reason being degradation because of infrequent use or aging.
The speed control and the solenoid work in tandem. Therefore, if you are planning to replace the speed controller, it would be advisable to replace the solenoid too. Even if the solenoid looks fine, you should get it replaced while getting a new speed controller.
Why Club Car DS won’t accelerate?
When your Club Car DS does not accelerate, it could mean that there is a problem with the spark plug. Get the spark plug removed and check it thoroughly. If it is oily or emits a foul smell, you need to clean it thoroughly or, if possible, get it replaced.
If the plug seems to be fine, then connect the threads of the spark plug to the metallic part of the engine and turn around the engine a few times. If you see a spark near the electrode, it is a good sign. If you do not see a spark, it means the coil is not in good condition.
Why Club Car Precedent won’t accelerate?
A problem with the fuel pump could be the reason behind your Club Car Precedent not accelerating. Carts that run on gasoline have fuel pumps with three hoses attached to them. Apart from gasoline-in and gasoline-out, there is a third hose that is hooked to the crankcase vacuum.
A diaphragm is present inside the fuel pump that is drawn inside and outside the device with the help of the crankcase pressure. This crankcase pressure is a result of the piston moving upward and downward.
You must check these hoses regularly to ensure that there are no leaks or cracks in them. If you have spare tubing at your disposal, you can get these hoses replaced anytime in case of a leak or a crack.
Why Yamaha G1 golf cart won’t accelerate?
Your Yamaha G1 golf cart may start up easily and you hear the solenoid making a click sound when you press the pedal. Despite this, if the vehicle suffers from acceleration problems, you could try pushing and releasing the pedal several times.
You should examine the air filters and see if they are working properly. You must also check the belt tension and figure out if the machine needs a new belt. The cart will also not move if it is not getting the right amount of voltage.
Why Yamaha G2 golf cart won’t accelerate?
There are several reasons why your Yamaha G2 golf cart may not be accelerating. You need to check a couple of things while trying to fix this issue. Check if the fuel flow is working properly. You can do so by pulling out the fuel line from the carburetor.
If the carburetor has not been cleaned for a while, clean it thoroughly. Find out if the throttle cable is able to open the throttle completely.
One also needs to have a good look at the air cleaner box to find out whether it has been sealed properly and tightly. A blockage in any of the parts that are responsible for air intake, such as filter, intake hose, or airbox could also lead to a problem in acceleration.
Why Yamaha G16 golf cart won’t accelerate?
The mass airflow sensor, which is also referred to as the meter, is a device that is located close to the inlet air cleaner. The airflow sensor serves the function of measuring the air mass that is getting into the system of the vehicle.
An airflow sensor that is clogged will send inaccurate data or information to the engine ECU for arriving at the calculation of the airflow mixture. One of the most common signs of an airflow meter of a Yamaha G16 golf cart malfunctioning is the vehicle not accelerating or moving forward.
Why Yamaha G29 golf cart won’t accelerate?
An oxygen sensor is a component that monitors the operation of the exhaust emissions of the golf cart. This device helps the cart in calculating the air-fuel ratio of the golf cart’s engine.
A golf cart must have a good amount of fuel at any given point in time so that the combustion cylinders can burn as much fuel as required for it to move smoothly and have proper acceleration.
The oxygen sensor communicates the information about the fuel consumption to the engine. Therefore, if the oxygen sensor is damaged, the engine of the Yamaha G29 golf cart will be oblivious to any information about the air-fuel mixture. This will, invariably, cause acceleration problems.
