Delco Remy Generator Wiring Diagram – A Comprehensive Guide

Generators are an essential part of an automobile’s electrical system. The Delco Remy generator is one of the most popular generators used in many vehicles. The wiring diagram of this generator is crucial to understand for troubleshooting and repair. In this article, we will discuss the Delco Remy generator wiring diagram in detail.

What is a Delco Remy Generator?

Delco Remy generators are a type of alternator that is widely used in vehicles. They are known for their reliability, durability, and excellent performance. These generators are equipped with various features, including a built-in voltage regulator, which helps in regulating the voltage output.

How does a Delco Remy generator work?

The Delco Remy generator works by converting mechanical energy into electrical energy. The generator consists of two parts: the rotor and the stator. The rotor is a rotating component that has a wire winding, while the stator is the stationary part that contains wire windings.When the engine is running, the rotor rotates inside the stator, which creates an electromagnetic field. The wire windings in the stator then generate an electrical current, which is sent to the battery for storage.

Why is the Delco Remy generator wiring diagram important?

The Delco Remy generator wiring diagram is essential for understanding how the generator works and troubleshooting any issues that may arise. The diagram provides valuable information on the various components of the generator, including the wiring, voltage regulator, and ground connections.Understanding the wiring diagram can help in diagnosing problems such as a low charging output, a dead battery, or a malfunctioning voltage regulator. It also helps in identifying the correct wiring connections during installation or repair.

The Delco Remy Generator Wiring Diagram

The Delco Remy generator wiring diagram consists of various components, including the battery, generator, voltage regulator, starter, and ignition switch. Let’s take a closer look at each of these components and their wiring connections.

Battery

The battery is the heart of the electrical system, and it plays a crucial role in the functioning of the generator. The positive (+) terminal of the battery is connected to the generator’s output terminal (BAT), while the negative (-) terminal is connected to the vehicle’s ground.

Generator

The generator consists of various components, including the rotor, stator, brushes, and slip rings. The wiring connections for the generator are as follows:

  • The output terminal (BAT) is connected to the positive (+) terminal of the battery.
  • The field terminal (FLD) is connected to the voltage regulator’s F terminal.
  • The ground terminal (GRD) is connected to the vehicle’s ground.

Voltage Regulator

The voltage regulator is responsible for regulating the generator’s output voltage. The wiring connections for the voltage regulator are as follows:

  • The B terminal is connected to the positive (+) terminal of the battery.
  • The F terminal is connected to the generator’s field terminal (FLD).
  • The G terminal is connected to the vehicle’s ground.

Starter

The starter is responsible for starting the engine by cranking it over. The wiring connections for the starter are as follows:

  • The battery’s positive (+) cable is connected to the starter’s large terminal (BAT).
  • The ignition switch’s start terminal (ST) is connected to the starter’s small terminal (S).

Ignition Switch

The ignition switch is responsible for controlling the electrical system’s power flow. The wiring connections for the ignition switch are as follows:

  • The battery’s positive (+) cable is connected to the ignition switch’s B terminal.
  • The start terminal (ST) is connected to the starter’s small terminal (S).
  • The accessory terminal (ACC) is connected to various accessories such as radio, lights, and wiper motor.
  • The ignition terminal (IGN) is connected to the coil’s positive (+) terminal.

Frequently Asked Questions (FAQs)

1. What is the output voltage of a Delco Remy generator?

The output voltage of a Delco Remy generator is usually between 13.5 to 14.5 volts.

2. What causes a low charging output from a Delco Remy generator?

A low charging output from a Delco Remy generator can be caused by several factors, including a faulty voltage regulator, worn brushes, a loose belt, or a damaged rotor or stator.

3. How do I test a Delco Remy generator?

You can test a Delco Remy generator by using a voltmeter to measure the output voltage. The voltage should be between 13.5 to 14.5 volts. You can also check the brushes, belt, rotor, and stator for any signs of wear or damage.

4. How do I install a Delco Remy generator?

To install a Delco Remy generator, follow these steps:

  1. Disconnect the battery cables.
  2. Remove the old generator.
  3. Install the new generator and connect the wiring connections.
  4. Tighten the belt tensioner to the recommended torque specification.
  5. Reconnect the battery cables.

5. Can I repair a Delco Remy generator?

Yes, you can repair a Delco Remy generator by replacing the faulty components such as the brushes, voltage regulator, or bearings. However, if the rotor or stator is damaged, it may be more cost-effective to replace the entire generator.
