Jun 22, 2022 · A signal of the power supply duty ratio for the alternator field coil is inputted to the engine-A/T-ECU. In response to the signal, the engine-A/T-ECU detects the alternator output current and controls the idling speed according to the output current (electric load).
In this case, I measured 2.58 milli-seconds or 0.00258 seconds. So now, to compute the rpm of this alternator, we first have to convert the .00258 seconds-per-wave into waves-per-second, called frequency (in Hertz). 1/.00258 = 388 Hz. But we want it in minutes,not seconds, so 388 X 60 = 23280 waves per minute.

The first thing you need to know about your alternator is the way it’s wired. There are two wires that come from the alternator. One of them connects to the dashboard light and the other to a diode or LED. When the ignition switch is in the on position, the positive lead goes through the diode to the battery, which delivers power to the alternator....
The three connections on an alternator are the positive wire, the negative wire, and the ground wire. The positive wire connects to the positive terminal of the battery, while the negative wire connects to the negative terminal. The positive wire also connects to the battery charging cable, which is responsible for charging the battery. The negativ...
The B+ and D+ terminals on your alternator are the positive and negative connections of the battery. A European alternator has a D+ signal. This signal indicates that the battery voltage is at least 12.5 volts. If it is less than this level, the dash signal light will come on. The W terminal connects to a small wire near the bottom of the alternato...
The D+ terminal of an alternator is connected to a charge warning lamp. It also provides earth to the battery light and switches on the field coil. The voltage regulator controls the current to and from the D+ terminal to maintain a system voltage of about 14 volts. If the D+ terminal is disconnected, very little or no output is produced. The D+ te...
In an automobile, the alternator is the most important component. It converts mechanical energy into electrical energy and recharges the battery. There are two small wires that run to and from it: the battery charging wire and the ignition input wire. The latter leads to the key switch and activates the voltage regulator. The first one is referred ...
The two wires on an alternator have very important functions. They send power from the battery to the alternator. They also provide voltage sensing, which tells the internal regulator how hard it should work to maintain 14 volts. Unfortunately, the voltage can fall due to fuses, connectors, and undersized wires. Because of this, car manufacturers r...
An alternator has three phases of power. The first phase covers the North pole magnets and wraps the magnetic field in the same direction. The second phase offsets the magnetic field in equal amounts. This diagram shows the sets of wires on a three-phase alternator. There are 3 start wires and three end wires. The stator consists of three windings,...
The first thing to know is that a three-wire alternator requires two extra wires in your vehicle’s electrical system. However, there are some benefits to a single-wire unit. These include the ease of installation and less time spent on installation. These units also have better electrical performance. The difference between a single wire and three-...
IG is the ignition input that turns on the alternator/regulator assembly. S is used by the regulator to moni-tor charging voltage at the battery. L is the wire the regulator uses to ground the charge warning lamp. Alternator Terminal Identification.
B is the alternator output wire that supplies current to the battery. IG is the ignition input that turns on the alternator/regulator assembly. S is used by the regulator to monitor charging voltage at the battery. L is the wire the regulator uses to ground the charge warning lamp.

Feb 7, 2023 · The alternator’s sense wire, or “S” wire, monitors battery voltage and provides a signal to change its output. The battery’s positive terminal or the alternator’s sense terminal connects this wire. The precise position of the sensing wire is determined by the alternator and vehicle type.
Mar 7, 2023 · The W terminal on an alternator is the output signal to the tachometer. To be more specific, it creates an AC voltage whose frequency is proportional to the rotational speed of the engine. In other words, as the engine speed increases, so does the frequency of the AC voltage.
