The Bosch 2 wire alternator is a common type of alternator found on many types of vehicles. It is a simple and reliable design, and is easy to install and maintain. In this article, we will discuss the basic principles of the Bosch 2 wire alternator, and provide a wiring diagram that you can use to install one on your vehicle.
Principles of the Bosch 2 Wire Alternator
The Bosch 2 wire alternator is a type of alternator that uses a voltage regulator to control the output voltage. It has two wires that connect to the battery, one for the positive (+) terminal and one for the negative (-) terminal. The voltage regulator controls the amount of current that is fed to the battery, and ensures that the battery is charged at the correct voltage.
The Bosch 2 wire alternator is a self-exciting alternator, which means that it does not require an external voltage regulator to operate. Instead, it uses a voltage sensing wire that connects to a dashboard warning light or an ammeter. When the engine starts, the alternator begins to produce electricity, and the voltage sensing wire detects the output voltage. If the battery is not fully charged, the voltage regulator increases the current output to charge the battery. If the battery is fully charged, the voltage regulator reduces the current output to prevent overcharging.
The Bosch 2 wire alternator is a compact and lightweight design, and is suitable for use on a wide range of vehicles. It is also very reliable, and requires very little maintenance.

To wire the Bosch 2 wire alternator, follow these steps:
- Disconnect the negative (-) terminal of the battery.
- Connect the positive (+) terminal of the battery to the alternator’s positive (+) terminal.
- Connect the negative (-) terminal of the battery to the alternator’s negative (-) terminal.
- Connect the voltage sensing wire to the alternator’s D+ terminal. This wire should be connected to a dashboard warning light or an ammeter.
Once you have wired the Bosch 2 wire alternator, you can start the engine and check the output voltage. If the battery is not fully charged, the dashboard warning light or ammeter should show a positive current flow. If the battery is fully charged, the dashboard warning light or ammeter should show a zero current flow.
Frequently Asked Questions
What is a voltage regulator?
A voltage regulator is an electronic device that controls the amount of voltage that is fed to a battery or other electrical load. It ensures that the voltage is maintained at a steady level, regardless of the input voltage or load conditions.
What is a self-exciting alternator?
A self-exciting alternator is an alternator that does not require an external voltage regulator to operate. Instead, it uses a voltage sensing wire to detect the output voltage, and adjusts the current output accordingly to charge the battery.
What vehicles are compatible with the Bosch 2 wire alternator?
The Bosch 2 wire alternator is suitable for use on a wide range of vehicles, including cars, trucks, and boats. It is a popular choice for hot rods, custom cars, and other custom vehicles.
Is the Bosch 2 wire alternator easy to install?
Yes, the Bosch 2 wire alternator is very easy to install. It has a simple and reliable design, and requires only basic electrical knowledge and tools.
How do I check the output voltage of the Bosch 2 wire alternator?
To check the output voltage of the Bosch 2 wire alternator, you can use a digital multimeter. Connect the multimeter to the positive and negative terminals of the battery, and start the engine. The output voltage should be between 13.5 and 14.5 volts.
In conclusion, the Bosch 2 wire alternator is a simple and reliable design that is easy to install and maintain. By following the wiring diagram and instructions provided in this article, you can install a Bosch 2 wire alternator on your vehicle and enjoy a reliable and efficient charging system.
