Should be around 13.5-15.5 volts.
Output of the alternator is controlled by the voltage regulator.
It controlls the output voltage of the alternator.
The AVR (Automatic Voltage Regulator) control the DC field voltage to the rotor of the alternator, as soon as higher load is demanded from the alternator, the AVR output voltage go higher, hence, a higher AC voltage on the output of the alternator. If the voltage go to high then the AVR is faulty.
It controls the output voltage.
the speed sensor for 2004 Mitsubishi Galant is located on the front case of the transmission output shaft and speed sensor. It is approximately under the hood to the left of the engine.
The alternator is not adjustable. The computer controls the voltage output.
Regulation of an alternator is varying or adjusting the d.c. current flow (excitation current) in the revolving field coil to control the output voltage. When an alternator is subject to varying load conditions, and therefore changing load resistance at the output, the output voltage will vary in response. When output voltage is reduced in response to increased load (reduced output resistance), the "voltage regulator" will respond by increasing the excitation current to increase the voltage output. If load is reduced, the generator will momentarily become over-excited and the ouput voltage will increase. The voltage regulator responds by decreasing excitation current, returning the generator output voltage to its nominal level.
No. It controls the output of the alternator.
Automotive Alternator Output VoltagesWith a properly operating alternator, AND electrical system, a voltage output range of 13.5 Volts to 16 Volts is considered acceptable.Just the alternator puts out around 120 vac, but most newer alternators include a built in rectifier that limits voltage output to between 13.5 and 15.5 volts DC depending on speed.
Inside the alternator. It's part of the alternator. If you are having problems with low or high voltage output, I'd recommend replacing the alternator as a unit.
Alternator Output Voltage RangeGenerally, alternator output voltage is consider OK if it is in the range between 12 1/2 volts to a maximum of 16 volts.Therefore, although the output is at the maximum, you do not seem to have a problem.Usually, if the battery has had a lot of drain, then the alternator output will run at the maximum until the battery is fully charged.
The alternator output voltage in most modern 12 volt automotive systems ranges from 13.5V to 14.5V, with the nominally accepted value being 13.8V. The actual voltage depends on battery charge state and temperature.
For alternator electrical circuit input voltage = output voltage + ( current * alternator_impedance ) alternator internal developed voltage ( in the above equation it is referred as input voltage ) is constant, since the speed of rotation and field is constant throughout the operation. alternator impedance is constant, but current is not constant. current varies as the load impedance varies. The output voltage is less than the input voltage for inductance loading while for capacitance loading output voltage might be more if resistive voltage drop is less. Let us take resistance is negligible ( R = 0 ) then for inductance load Current lags input voltage by 90 deg, then the voltage drop in the alternator impedance is exactly 180 deg in phase with input voltage so the output voltage is lower than input voltage. In the same way for capacitance load current leads input voltage by 90 deg and voltage drop in capacitance is in phase with the input voltage so output voltage is more than the input voltage or internally developed voltage. so as the capacitance load increases i.e current increases the voltage drop across the alternator impedance increase, which is exactly in phase with the input voltage, so output voltage increases as capacitance load increases. All the above explanation is true in terms of phase angles only if alternator resistance is zero and also load resistance is zero. In practice it is not possible. So the current leads the input voltage by an angle for capacitance load. If we take the voltage drop in the alternator impedance, it can be divided in to two parts 1: Alternator internal Resistive drop 2: Alternator internal Inductance drop The resistance drop always subtracts the input voltage, but inductance drop adds the input voltage for leading current, so output voltage increases, that's why there is some minimum capacitance load required to make the output voltage = input voltage. As the capacitance load increases current increases as well as the leading P.f angle increases so output voltage increases.
Normal voltage, checking at the battery or alternator should be in the 14 range.
The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.
The alternator may not be able to keep up to the voltage requirement of the vehicle check voltage output of alternator w/mechanical gauge
it controls the amount of voltage that is flowing in a circuit. To be more accurate, a voltage regulator provides a limiting mechanism to an electrical or electronic power source. In the case of modern automotive alternators the voltage regulator "regulates" the output from the alternator by limiting the current flowing through the rotating field assembly inside the alternator. The weaker the electromagnetic field of this "rotor" the lower the output (both current and voltage) of the alternator. When the electrical load on the alternator is low the regulator reduces the field strength based on it's set upper voltage limit. When the load increases beyond the capacity of the "limited" output the voltage drops (the load is kind of "shorting out" the power from the alternator) and the regulator allows the field current (and therefor the output of the alternator) to rise until the voltage reaches that "upper limit" again and so on. Hope this helps
on any 12v car, the alternator output should be between 13.6v to 14.4.
13.5 to 16 volts DC.
Charging System Output Voltage RangeTo my knowledge, unless there are vehicles that are exceptions, the acceptable output voltage specifications for all auto alternators is within the range of 13 volts to a maximum of 14.6 volts.
13.9 to 14.3 volts with engine running.
The charging system output voltage is too high or low.
14.3 to 14.6v dc
The battery light is for low alternator output voltage. Try testing the alternator output using a miltimeter and if its less than 13 volts your alternator isn't putting out what it should. If it has low output check the belt tension and all wire connections before replacing alternator
An alternator is controlled by a voltage regulator. The regulator can be part of the alt., the computer, or a stand alone unit. The regulator controls the amount of current in the field windings which then controls the voltage output.
