Do you need a voltage regulator with a one wire alternator?
The only thing required to electronically hookup a one wire alternator is to run a charge wire from the battery terminal on the alternator to the positive terminal on the battery (or any positive battery source). The external regulator can be either totally removed from the firewall or left in place.
What is a 3 pin alternator?
Most cars originally came with a 3-wire alternator. As its name implies, the 3-wire alternator has three electrical connections to it. The first is the large lug that connects to the battery. This is the main current feed that charges the battery and powers the car when the engine is running.
Where does the alternator exciter wire go?
Voltage goes through the light and down the exciter wire to the alternator. The wire is connected to the “L” terminal of the alternator. The exciter wire is used to turn on the voltage regulator.

How to charge a battery when the engine is running?
First, you need to connect the alternator directly to the positive terminal on the battery. This is how the battery gets charged when the engine is running. It is very important to make sure that nothing interrupts this feed to the battery.
Does the alternator light when the bulb is on?
There is no net voltage drop across the bulb so it does not light. If your alternator stops generating current when the ignition is on and the engine is running, you back to the first scenario. There is voltage on the POWERCELL side but no voltage on the alternator side.
How do I wire a 3 way alternator to a tractor?
As I mentioned in the previous step-by-step guide, the first thing to do when wiring a 3-way alternator to your old tractor is to disconnect the battery negative terminal. This step is very important and must not be avoided.

The magnetic field creates a current which feeds through the alternator charge the car's battery. The three wire types in a three-wire alternator include the battery positive wire, the voltage sensing wire, and the ignition input wire. The battery positive wire connects to the starter.
What is an alternator regulator?
Alternators have an internal regulator that monitors the amount of volts going to the battery. Should the voltage raise or decrease drastically, the regulator will increase or decrease the output of the alternator to maintain a steady flow of voltage to the battery.
Why do car lights need alternators?
The headlights, dashboard lights, radio and interior lights all rely on the alternator to keep the battery charged and the car operating. The alternator has a rotor that spins when the engine cranks. This rotor spins past wire coils causing a magnetic field.
Can an alternator be replaced if it breaks?
Alternators with only one wire have an external regulator, which means that the regulator can be replaced if broken.

Some vintage vehicles use an electromechanical voltage regulator that’s external from the alternator.
What is the purpose of an alternator?
The alternator accomplishes these tasks through electromagnetic induction —a phenomenon that generates electrical current from a magnetic field. The alternator’s stator (background), rotor (center), and rectifier (foreground). The primary components found within the alternator are the rotor, stator, and rectifier bridge.
