How do you make a homemade alternator? 

How do you make an alternator out of an air conditioner? 

What materials make up an alternator? A basic alternator is made up of a series of alternating finger pole pieces placed around coil wires called field windings that wrap around an iron core on the rotor shaft. Since we know the pulley attaches to the shaft, we can now visualize how the rotor spins inside the stator.

What makes a high output alternator? The term “high-output” for alternators simply means the new, rebuilt, or rewound unit is capable of producing more amps across the board than a stock unit. In the realm of diesel pickups, a high-output alternator produces more than three times the amp output of a stock alternator.

How do you make a homemade alternator? – Additional Questions

Can an alternator be too powerful?

You can never have too much amperage when it comes to alternators; therefore, you never have to worry about choosing an alternator with too high of a rated output. Here’s why: Amperage is basically the amount of electrical current your alternator can supply. And it basically operates off of supply and demand.

What size alternator do I need for 3000 watt amp?

3000 watt / 12V is equal to 250A. A 250A alternator is needed to keep up with it. Since your engine would have to work just as hard as any portable 3KW generator to keep up with the amplifier, you would need a large fuel tank.

How do I know if my alternator is high output?

To qualify as a high output unit, an alternator needs to provide more amperage than the factory unit that it replaced. That means there is a big difference between a high output unit that provides 100A at idle speeds and a water-cooled unit that provides upwards of 350A.

What size alternator do I need for 1000 watt amp?

If you’ve read this far and are starting to rethink 150’s, hair tricks, and broken windshields, you can still enjoy considerable bass with a single high output alternator in your car or truck. As a general rule, you need about 100 amps of current for every 1000 watts of power generated.

What size alternator do I need for 2000 watt amp?

To figure out how much capacity or amperage the alternator must deliver, determine how much extra power the audio system demands on top of the current system. For example, if you installed a 2,000-watt amp, assuming a nominal voltage of 13.5V, you’d add roughly 150 amps of demand to the electrical system.

Is a 220 amp alternator good?

With some extra work there are ways to get decent charge going, but even then the 220A alternator is probably enough for most scenarios if there are no other non-vehicle loads.

What is the big 3 upgrade?

The upgrades in the Big Three are: The run from the alternator chassis to the negative terminal of the battery. The run from the output of the alternator to the positive terminal of the battery. The ground connection from the negative terminal of the battery to the chassis of the vehicle.

What is the highest amp alternator?

Remy International has released the Delco Remy 55SI alternator, rated at 420 amps at 12 volts and up to 275 amps at 24 volts.

What gauge wire should I use for my alternator?

High-output alternators need a large charging wire. That skinny 12 gauge wire at the top is too small while the wire connected to the alternator is 10 gauge, which should be considered the minimum. The fat wire is 6 AWG wire and would be the most preferable.

Can I wire my alternator directly to my battery?

No, you cannot straight wire your alternator directly to your battery. You will need to attach a cable directly to the positive side of the battery from the alternator output post. This is because when heavy electrical demands are placed on the alternator, the battery will help the alternator to produce full output.

Do I need a fuse between alternator and battery?

Does a one wire alternator need to be grounded?

Being a true one-wire alternator means that having a solid ground and an ample wire attached to the battery is all that you’ll need to keep that battery charged, and will do so with 100 amps output or more.

How do I convert my alternator to one wire?

Do I need a voltage regulator with an alternator?

Without the alternator voltage regulator, the input voltage would be too great and overload the electrical systems in your vehicle. To prevent that, the voltage regulator functions much like a linear regulator in that it ensures the alternator output maintains a steady charging voltage of between 13.5V and 14.5V.

What are the 2 wires on an alternator?

Wiring Connections

Exciter wire is connected to the L terminal of an alternator and is used to turn on the voltage regulator. Excitor wire is needed to generate the voltage required for the alternator to start running. The positive and negative cables are small and connected to the respective terminals of the battery.

What does R mean on alternator?

The “R” terminal or Relay terminal as it is sometimes called, provided some of the alternator’s output and was used to power electric tachometers, a dash light, hour meters, or other modern accessories. In some applications it was connected to the dash light to give notice if the alternator was failing to charge.

How do you force an alternator to charge?

What does D+ mean on a alternator?

The way I understand the setup, D+ measures the voltage at the battery, and the delta between that and the preset voltage in the regulator drives the field to increase/decrease the output of the generator.

What does P mean on an alternator?

Neutral. Centre point of a Y-connected stator. P. Pulse. Stator connection for tachometer.

What does B mean on an alternator?

AC: Neutral or Star. AS: Voltage sense, external. B+: Battery. B-: Earth.

What does C mean on alternator?

C: (Computer Controlled) This terminal is an input signal from the ECU which controls the charge rate. This signal will tell the alternator when to stop/start charging. This terminal can be tested by connecting into ground and the Voltage Set Point (VSP) should show a voltage of around 12.8V.
