1. Understanding the Electrical System

The electrical system of the 1987 EZ Go Golf Cart consists of a battery, solenoid, speed controller, motor and various wires that connect these components together. The battery supplies power to the system, the solenoid connects the battery to the speed controller, and the speed controller regulates the power sent to the motor.

It is important to note that the electrical system of the 1987 EZ Go Golf Cart is a 36-volt system. This means that there are three 12-volt batteries connected in series to provide the necessary power.

Understanding the electrical system is crucial for troubleshooting and repairing any issues that may arise. Without a good understanding of the system, it can be difficult to isolate the problem and fix it.

1.1 Battery

The battery is the heart of the electrical system. It provides power to the system and needs to be maintained properly to ensure proper functioning of the golf cart. The 1987 EZ Go Golf Cart uses three 12-volt batteries connected in series to produce a total of 36 volts.

It is important to check the battery voltage regularly to ensure they are fully charged. The battery terminals should also be cleaned and checked for any signs of corrosion.

1.2 Solenoid

The solenoid is an electromagnetic switch that connects the battery to the speed controller. When the key is turned on, power is sent to the solenoid which then connects the battery to the speed controller, allowing the golf cart to move.

The solenoid is a common source of issues with golf carts. If the solenoid fails, the golf cart will not move. It is important to ensure the solenoid is functioning properly and is securely connected.

1.3 Speed Controller

The speed controller regulates the power sent to the motor, controlling the speed of the golf cart. It is an essential component of the electrical system and must be in good working order for the golf cart to function properly.

Issues with the speed controller can often be a result of other components in the system failing. It is important to check the battery and solenoid before replacing the speed controller.

1.4 Motor

The motor is the component that drives the golf cart. It receives power from the speed controller and rotates the wheels, allowing the golf cart to move.

If the golf cart is not moving, it is important to check the motor for any issues. The brushes should be checked and replaced if necessary, and the connections should be checked for any signs of damage or corrosion.
