They are located on the top of the alternator. The other two connectors are smaller spade connectors. The first large connector connects a battery and an alternator.

That field is used for producing electricity. From there, the coil creates the magnetic field. The fourth wire handles deliver power to the field coil (windings). Its purpose is to notify the alternator about the current needs of the rest of the electrical systems in the car. The second wire is red, carrying the power from the alternator to the battery. The first wire is always the ground wire, usually black. If the alternator has four wires, we will explain its purpose and how to connect them. Below we will cover all of those wiring patterns in more detail, so you can know the difference. Alternator Wiring DiagramsĪbove, we described the case where the alternator has four wires, which is the most common case. The final wire delivers power to the field coil, where the magnetic field is created. The first one is the sense wire that notifies the alternator about the current use of power in the car. In the case of four, those are the main positive wire that supplies the electricity and the main negative wire that serves as a ground wire. In most cases, three or four wires go into the alternator.

It all depends on the type of alternator. The ring terminal connects the wire to the battery. A spade terminal connects the wire and the alternator. Two types of terminals are attributed to the wire harness of an alternator. Sometimes it can be a green or a blue color wire to mark an especially high voltage wire. The positive wire is always connected to the positive terminal on the battery. The red color is the most common color used for high-voltage wires. That is why using 10, 12, or 14-wire gauges is recommended. Connections can become too loose if the wiring is too thin. This way, the battery can always be recharged during the drive.Ĭheck Out How Alternators Work – Automotive Electricity Generator:Īlternator wiring demands a certain wire size.

There it can be stored and used when needed. The alternator is connected to the battery, and from windings, the electricity is sent to the battery.

The magnetic field goes through a series of coils called windings.

When you turn the ignition switch, the belt starts its rotation and creates a magnetic field. The internal components of the alternator are connected with a belt. At the same time, it can recharge all the used electricity during the drive. It handles producing electricity by converting mechanical energy into electricity.Īn alternator sends the electricity to the battery for usage and storage. But, the alternator is one of the most essential parts of the engine. When talking about the importance of engine parts, it is hard to pick some of them out. Final Considerations What is an Alternator What is the alternator, and how does it work? How many wires can go to the alternator? How to identify the wires? These are only some of the topics that we will explain. Knowing this will shed some light on the subject, but there is a lot more that we should cover. The last is the field ignition input wire connecting to the ignition warning lights. The sense wire connects to the side of the battery to the voltage regulator. The first red wire is a main positive that connects the alternator and the battery output port in the back. The black, negative wire has a grounding role and is connected to the chassis. The battery is recharged by a very important car component – an alternator.īut how can you wire an alternator to charge the battery constantly? Most alternators have four wires.

An ordinary battery would dry out very fast, so the car uses a rechargeable battery to power up everything. Besides that, a lot of other systems in the car demand a constant supply of electric power. Each starting of the car demands a lot of electricity.
