If you are the proud owner of a 1968 Dodge Charger, you know that this classic car is a true gem. However, as with any classic car, keeping it in good condition requires a bit of knowledge and effort. One important aspect of maintaining your 1968 Dodge Charger is understanding the alternator wiring diagram.
What Is an Alternator?
Before we dive into the wiring diagram, let’s first discuss what an alternator is and what it does. An alternator is an electrical generator that converts mechanical energy into electrical energy. It is responsible for keeping your car battery charged while the engine is running. Without an alternator, your car’s battery would quickly die and your car would no longer be able to start.
Your 1968 Dodge Charger originally came with a 60-amp alternator, which was considered powerful at the time. However, if you have made any modifications to your car, such as adding a high-powered sound system or electrical accessories, you may need to upgrade your alternator to keep up with the increased electrical demands.
Understanding the Alternator Wiring Diagram
The alternator wiring diagram for a 1968 Dodge Charger can be a bit confusing if you are not familiar with electrical diagrams. However, with a bit of patience and understanding, it is easy to decipher.
The wiring diagram consists of various wires that connect the alternator to the battery, starter, and other electrical components in your car. Understanding these wires and their connections is important if you ever need to repair or replace your alternator or any of its components.
Wire Colors
Before we dive into the specific connections in the wiring diagram, let’s first discuss the wire colors you will see. The wire colors used in the alternator wiring diagram are standardized across all car manufacturers. Here are the most common wire colors you will see:
| Wire Color | Function |
|---|---|
| Red | Battery positive (+) |
| Black | Battery negative (-) |
| Green | Field wire (controls alternator output) |
| Orange | Sense wire (monitors battery voltage) |
Connections
Now that you are familiar with the wire colors, let’s discuss the specific connections in the wiring diagram. Here is a breakdown of what each wire does:
Red Wire
The red wire connects the alternator to the battery positive (+) terminal. This is the wire that charges your battery while the engine is running. If this wire is not connected properly, your alternator will not function.
Black Wire
The black wire connects the alternator to the battery negative (-) terminal. This completes the charging circuit and ensures proper electrical grounding.
Green Wire
The green wire is the field wire and is responsible for controlling the alternator’s output. This wire connects to the voltage regulator, which regulates the voltage output of the alternator based on the electrical demands of your car. If this wire is not connected or is connected incorrectly, your alternator may not function properly.
Orange Wire
The orange wire is the sense wire and is responsible for monitoring the battery’s voltage. This wire connects to the voltage regulator and ensures that your alternator is charging your battery properly. If this wire is not connected, your alternator may overcharge your battery or not charge it at all.
