#SUBARU 3 WIRE ALTERNATOR WIRING DIAGRAM CODE#

How do I wire my alternator straight to the battery? When you turn the key to ‘run,’ the exciter wire is connected to the L terminal. The light will trigger the alternator to start producing electricity. If you have a 10 or 12-SI alternator, the exciter wire will be connected to the light. It is usually connected to the charge indicator light, which is powered by the ignition switch.

The exciter wire is a small strand of wire that is connected to a switch on the alternator. The alternator also has an ignition input wire that connects to the key switch to activate the voltage regulator. If your car has a 3-wire alternator, it also detects voltage at the ignition and fuse block, and charges more to bring all systems up to power. The ‘battery charging wire’ on the alternator shows that the positive side is connected to the battery. The positive and negative alternator cables connect to the battery. The exciter wire is actually not necessary with most modern vehicles as they have internal voltage regulators. In fact, pusher alternators have been around for more than 40 years! Without the exciter wire, your volt meter won’t indicate a charge until you start your car and start to rev the engine. There is a popular misconception that pusher alternators don’t require the exciter wire. Do I need the exciter wire on alternator? Depending on its voltage, the alternator’s internal voltage adjusts itself so that it will maintain 12 Volts to the battery and all of your vehicle’s systems. This wire is connected to the positive (+) terminal of your battery, and it senses the voltage. One of the wires is the heavy guage white wire with a blue stripe. The two wires on your alternator come in three different colors. There is also an ‘ignition input wire’ which is connected to the key switch to turn on the voltage regulator.(Indicator) This wire supplies energy to your battery, and the alternator has no other purpose. Another connection that connects to the alternator is known as the ‘battery charging wire’. The positive and negative cables are connected to the positive and negative terminals of your battery, respectively. You probably have asked yourself: What are the two wires on an alternator? First of all, there are two main connections. Depending on the make and model of your vehicle, you can replace either of them if needed. A 2 wire alternator wiring diagram shows the connection between them.

You can find the code for this wire on the Internet. It connects to terminal 2 through a small circuit. This wire delivers power to the alternator. The positive wire goes to the battery and contains a red o-ring. It is important to understand how the voltage regulator and alternator connect. To identify each of the other connections, follow the same procedure as described above.

The second connection is the positive (possibly fuseable) terminal and is connected directly to the battery. It allows power to flow through the alternator and other components of your car. This connection is also called the output connection.
