In the TM, part 10929869 is a Generator, Engine AC 60 amp. also came in a 100 amp version
figure 35 of tm 9-2320-280-24p=1
used on basic and 1a vehicles.
then 100 amp alternator started on a2 models
the 200 amp alternator began with the basic and a1 m996, m997, and m1097.
then a2 went to 200 amp alternators.
Stolen from The Internet:
An alternator and a generator are both devices that are used to generate electricity.
Alternators can be termed as types of generators. Even if these devices are used for the same function, they are different in terms of operation.
Alternators are charging systems in vehicles that are used to produce electricity.
Generators are used to produce bulk power.
Both generators and alternators convert mechanical energy into electrical energy through magnetic polarization. Both can work as electric motors if they are supplied with electrical energy rather than mechanical energy.
Alternator vs Generator
The Alternator
An alternator is considered a unique type of generator that can be utilized to convert mechanical energy into electrical energy that gets generated as alternating current. The device is mostly used in the automotive industry to convert mechanical energy into electrical power that can charge the car battery.
The mechanical energy is used to rotate a magnet — the turning of the magnetic field results into a change in magnetic flux which produces current. The alternators directly distribute the produced currently without converting it to DC.
Alternators are devices that are very efficient in the production of energy as they generate electricity only when it is needed. It would be correct to say that they are a contemporary edition of the generator that works to minimize the amount of energy used and minimize the amount of energy wasted. After installing an alternator, there is no polarization needed.
The only precaution needed when using alternators is that they are not suitable for charging completely drained batteries. Trying to do so can cause fire and also damage the environment.
Too little or too much voltage can also damage your battery and other electrical components in your car.
As a result, alternators have voltage regulators that determine how much and when energy is required in the battery.
The Generator
A generator is an electrical device used to convert mechanical energy into electrical energy – it can either produce alternating current (AC) or direct current (DC). How a generator works is what makes it different from an alternator.
The rotor, which consists of coiled wires, is put inside a magnetic field. The rotating of the coiled wires is what generates the electricity. The magnet remains stationary and produces a magnetic field, and the engine’s mechanical energy is utilized to spin the armature.
Since
the generators produce voltage throughout and consume all the generated energy, they are primarily used for large-scale electricity production.
Generators get polarized naturally after their installation.
They can even be utilized to charge wholly drained batteries. The direct current produced by a generator is generated when the rotor is connected to the commutator. The commutator is a critical element in the production of direct current in a generator – it consists of a set of separate rings which attach the generator to an external circuit in a way that the current produced is often DC.
BUT but but this has been covered a zillion times.
