If you are looking to troubleshoot electrical issues with your 85 Club Car golf cart, having a wiring diagram can be a lifesaver. This article will take you through the various components of your Club Car’s electrical system and provide you with a detailed wiring diagram to help you diagnose and resolve any issues. So let’s get started!
The Battery
At the heart of your Club Car’s electrical system is its battery. In most cases, a 36-volt battery powers your golf cart. The battery pack is made up of six 6-volt batteries connected in series, providing a total of 36 volts. These batteries provide power to the motor, controller, and other electrical components of your golf cart.
It’s essential to maintain your battery pack regularly to keep your golf cart running smoothly. Proper maintenance includes checking the water level, cleaning the terminals, and charging the battery pack regularly.
How to Check the Water Level
Checking the water level in your battery pack is essential. Not doing so can cause irreversible damage to your batteries. To check the water level, you will need to follow these steps:
| Step | Description |
|---|---|
| Step 1 | Locate the battery pack under the seat of your golf cart. |
| Step 2 | Remove the vent caps from each battery. The vent caps are usually located on the top of the battery. |
| Step 3 | Check the water level in each battery. The water level should be about 1/2 inch to 3/4 inch above the plates. |
| Step 4 | If the water level is low, add distilled water until the level is between 1/2 inch to 3/4 inch above the plates. |
| Step 5 | Replace the vent caps on each battery. |
The Motor
The motor is the power source for your golf cart. It converts electrical energy from the battery into mechanical energy, which drives the wheels of your golf cart. In most cases, the motor in a 36-volt Club Car is a series-wound motor.
A series-wound motor has two sets of windings: one set is on the stator, and the other set is on the rotor. The stator windings are connected in series with the armature, and the rotor windings are connected in series with the field. When current flows through the motor, it creates a magnetic field that causes the rotor to turn, which drives the wheels of your golf cart.
How to Test the Motor
If you are experiencing issues with your golf cart’s motor, there are a few tests you can perform to diagnose the problem. These tests include:
| Test | Description |
|---|---|
| Motor Resistance Test | This test checks the resistance of the motor’s windings to determine if any are damaged or burnt out. |
| Motor Ground Test | This test checks for any ground connections that may be causing the motor to malfunction. |
| Motor Load Test | This test checks the motor’s ability to handle a load and determines if the motor is overheating under normal operating conditions. |
The Controller
The controller is the brain of your golf cart’s electrical system. It controls the current flow to the motor based on the driver’s commands. In most cases, a 36-volt Club Car will have a solid-state controller.
A solid-state controller uses electronic components to regulate the current flow to the motor. These components include transistors, diodes, and capacitors. The controller receives input from the accelerator pedal and sends output to the motor to control its speed and direction.
How to Test the Controller
If you are experiencing issues with your golf cart’s controller, there are a few tests you can perform to diagnose the problem. These tests include:
| Test | Description |
|---|---|
| Controller Input Test | This test checks the input to the controller to determine if it is receiving the correct signals from the accelerator pedal. |
| Controller Output Test | This test checks the output signals from the controller to determine if it is sending the correct signals to the motor. |
| Controller Resistance Test | This test checks the resistance of the controller to determine if any of the electronic components are faulty. |
