How does a golf cart motor work?
If you pressed the pedal, the golf cart would jackrabbit jump to full throttle. Control of the old-style DC motor was accomplished by resistance, usually stepping through three to five different speeds. This was controlled by solenoids redirecting the voltage through different resistance tap points.
How many volt battery does a golf cart have?
You’ll find that most vehicles in this category run with 24 to 36 Volt battery packs. If your golf cart is meant to carry multiple passengers, or over rocky and hilly terrain, you’ll need a more powerful drive train. These vehicles will have motors with 5 to 10 horsepower, and controllers that can deliver 300 to 600 AMPS.
What does a resistor do on a golf cart?
Prevents arcing across your solenoid terminals and keeps your electrical system safe.
What does the Diode do on a golf cart solenoid?
A diode is a protection device across the contactor coil (solenoid relay) and in general, is a one way gate for electricity. The contactor coil is an electromagnetic device in your electric vehicle which controls the flow of power to your electronic speed controller.
How do you test a 48 volt golf cart controller?
To test a club car precedent controller, connect a voltmeter between the negative terminal of your cart's battery and the M terminal on the controller. Then push the pedal down and look for a clicking noise from the solenoid. Your batteries should read as full.
What causes an electric golf cart to lose power?
If the coach goes without charge for a long time, the battery may lack the minimum voltage required to restart. Batteries also lose their efficiency with age. Golf Carts will run for approximately five years before the battery needs to be replaced or the charger will need replacement.
Why is there a resistor on a solenoid?
This resistor, typically seen across the two big posts of the solenoid, pre-charges the filter capacitors in the electronic speed controller. This pre-charge minimizes the voltage across the solenoid to reduce arcing on the contacts as they close.

How do I know if my speed controller is bad on my golf cart?
When your golf cart's speed controller isn't operating correctly, your cart will show it by running erratically or failing to drive at one constant speed. If your cart starts showing these symptoms, the first thing you should look at is your speed controller.
What does a potentiometer do on a golf cart?
It sends an electrical signal to the speed controller from the accelerator pedal, indicating the pedal's position. When it is working properly, the potentiometer allows your golf cart to accelerate smoothly. Find your potentiometer and inspect it for any cracks, broken parts, or disconnected wires.
Why is my golf cart not holding a charge?
If you find that your golf cart won't go very far on a full charge, then you probably need new batteries. Test them to make sure that the power on them is low; if indeed it is, then you need new batteries.
How do I reset my electric golf cart motor?
First, you'll want to reset your motor. It should have a small reset button (Usually it will be red) located near the main battery supply. Hit the reset button and then put the cover back on the motor. The next step would be to recharge your cart and try turning it on again. If it starts up then you're in luck!
Why does my electric golf cart hesitate when I accelerate?
In most cases, the hesitation problem occurs due to bad batteries. If you have bought new batteries for your EZGO RXV, make sure to fully charge them before the first use. Batteries should then be charged after every use. To keep the batteries in check, get a Digital MultiMeter to measure the individual voltage.
How fast does a golf cart go?
A normal club car in good condition is expected to move at a speed ranging from 12 to 15 mph. When your car runs at a speed slower than 8 or 7 mph, you should know that it has a problem that needs to be addressed. Using weak batteries over a prolonged period can result in long-term issues to the engine of your golf cart.
Why do golf cart solenoids get damaged?
These parts can get damaged easily because of various factors like high temperature in the engine. It is imperative to check the pack voltage that is present at the two posts surrounding the solenoid.
Why does my club car get hot?
The solenoid resistor on a Club Car golf cart can get hot because of a faulty speed sensor, faulty solenoid or by using batteries that are too old. Using Old batteries. Faulty speed sensor. Congested Muffler. Faulty speed sensor.
Why is my golf cart muffler so congested?
The congestion, apart from making the muffler malfunction, creates several long-term issues. To correct this problem, remove the muffler and heat the inside.
Why does my golf cart make a stuttering sound?
They are mostly found in golf carts that operate on AC motors. If the speed sensor malfunctions, the cart can slow down substantially. When the speed sensor makes a stuttering sound, you know that there is a problem with it. The speed sensor can also malfunction when the magnet inside the golf cart is damaged.
Why is my golf cart not starting?
A bad solenoid could be one of the possible reasons behind a golf cart not starting. If the cart happens to be gas-powered, the engine will not start. If it is powered by electricity, the cart will not move.
How to check battery health on a cart?
The first thing you could do while checking the health of the battery is to turn around the connector a couple of times. After that, try to start the engine again.
How much horsepower does a golf cart need?
These vehicles will have motors with 5 to 10 horsepower, and controllers that can deliver 300 to 600 AMPS.

What does a battery controller do?
With the controller you are able to control your acceleration and deceleration, as well as the speed at which your vehicle moves.
Why is a speed controller important?
The Importance of the Speed Controller. The main objective for the speed controller is, as the name implies, to control the vehicle speed. Let’s say you try to operate that old DC motor without a controller. Any time you apply throttle, the full battery current and voltage is sent to the motor.
What is the function of a speed controller?
In addition to controlling the vehicles speed, there are a few other functions that speed controllers can offer, regardless of the motor you are using. Battery Current Limiter: This protects the battery from excessive discharge. This also pulls back the battery current as it depletes, which prevents cell damage.
Do AC motors require a sensor?
Device Support on SPF ( Speed of Position Feedback): AC motors can require a sensor in order for the controller to operate smoothly and efficiently.
Can you run a golf cart without a speed controller?
If your golf cart is running an AC or Brushless DC motor , you won’t be going anywhere without a speed controller. In these specific types of motors, electrical signals fire back and forth which reverse in direction at different times. This must stay consistent, and has to be timed precisely with the motors rotation.
What does a golf cart controller do?
What does a golf cart controller do? As you can tell by this article, plenty! From being able to modify your golf cart speed, to managing all of the electrical components in perfect harmony, the controller really is the “heart” of your golf cart.
What happens if you push the pedal on a golf cart?

What is club car power drive?
Club Car’s Power Drive is a Series Motor System, on the market from 1990 and up. On the golf carts built in the years 1990 – 1994, the controller used a 0 to 5K potentiometer (36 Volt). In the years 1995 and up, they used 5K to 0 potentiometers (48 Volt).
How many volts does a battery need?
Battery voltage will range from 24 volts to 96 volts, flooded acid, or lithium-ion. Tire size will factor into the torque required for your purposes, and increasing the horsepower can mean you need to get a higher amperage controller, solenoids, switches, and cables.
How to control speed?
The speed controller can offer the following functions: 1 A controlled ramp up to speed if the full throttle is applied suddenly. From a standing start, AKA locked armature, a motor can initially take up to 20 times its normal operating current. This must not last more than a second or two to avoid damage to the system. 2 Protection from ground faults caused by accidental shorts. 3 Safely reversing the motor by taking the motor to a stop, then reversing polarity. 4 An overheating protection thermal shutoff to protect the controller from damage. 5 Battery voltage monitoring to prevent the complete drain of the charge. 6 Overcurrent limiting to protect the motor and electrical components from damage.
