Can you replace an alternator with a high output alternator?

The good news is that replacing a factory alternator with a high output alternator, in and of itself, isn’t going to damage the rest of the electronics in your car, even if the new alternator is much, much bigger than the old one. As an example that trends closer to the ridiculous than the likely,…

What happens when the alternator of a car is dead?

The alternator and the car’s battery work hand in hand. A good battery should give you service for the next five years before its lifespan ends. If your battery is dead, then it will not give power to the car’s alternator. The alternator normally lasts longer than the battery.

What should be the output of a 300A alternator?

So if all of the electronics in your car, put together, only draw 60A, then your beastly 300A alternator will only produce 60A. The way that current works is that any given electrical component will only draw as much amperage as it needs to operate.

Can a broken alternator lead to early failure?

In some circumstances, overloading an already anemic factory alternator can even lead to early failure. And if you just replace the broken down alternator with another one that has the same specifications, the same thing will probably just happen again. How Much Alternator Amperage Do You Need?

Can a bad alternator keep a car going indefinitely?

An alternator can help replenish the battery in your car, but it can’t keep it going indefinitely. This means it’s important to distinguish between a weak battery and a bad alternator.

Do you need to retrofit an alternator on a 1970 Chrysler?

Once your replacement unit has been located, you have two options for retrofitting these alternators, depending on your car’s production year. For cars newer than 1970, it is not necessary to adapt the alternator harness; your existing harness should have two field wires leading to the regulator on the back of the alternator.

How is the amperage of an alternator determined?

The alternator generates enough amperage to meet the needs of the combined electrical system at any given time, and then each component draws its share. In order to determine how much amperage a component is going to draw, you can divide its wattage by the voltage of the system.

How to choose a high amp alternator for a headlamp?

In order to determine how much amperage a component is going to draw, you can divide its wattage by the voltage of the system. So basic 50-watt headlamps are only going to pull maybe 4A (50W / 13.5V), even if your big amp is drawing many times more than that. Do You Really Need a High Amp Alternator?

Which is alternator do I have in my Silverado Sierra GMC Truck?

Thanks but my problem is that the truck doesn’t have its original engine. The first motor was also a 4.3 and hopefully the same alternator, but to be sure is there anyway I can tell on the alternator what its amperage is? Re: Which alternator do I have?

When did Delco alternators start replacing DC generators?

This is just a quick visual identification guide for Delco type alternators. First Alternator used on GM Vehicles to replace old DC Generators. External regulator mounted on the firewall. First used in 1963 on the Corvette. First internally regulated alternator used by GM. Replaced the externally regulated 10DN. Again, first used on the Corvette.

How big an alternator do I need for car audio?

There is a primary system to calculate the need amp also. Calculate the total amp drained by the car’s electrical system. Also, see the power amp capacity how much it can draw correctly. A 70 amp will need a minimum 80 or 85 amp capacity alternator.

What’s the best way to calculate the size of an alternator?

Although it is possible to calculate roughly the right size based on the maximum amperage you’ll be dealing with, a good rule of thumb is to just go with the thickest gauge that will work in the application.

What kind of alternator does a car before the 1970s have?

Cars made before the late 1970s have an alternator with an external voltage regulator. On European cars, they’re sometimes called a “three-wire alternator.”

Can a powerful alternator affect the audio system?

There is no history of getting any damage with a powerful alternator on the car’s system. It only cut huge money from you. That’s it. How can car audio capacitors can enhance my alternator’s work? A car capacitor cannot supply any power to your car’s audio system. It can filter energy that is provided by the alternator.

Do you need ground cable for high amp alternator?

Since a high amp alternator will be putting out a lot more juice than the factory unit, and your power and ground cables were chosen with the OEM unit in mind, these cables might not be big enough.

Do you need a high output alternator for a defroster?

In comparison, typical headlights are also about a 10A draw, a defroster can pull up to 15A, and air conditioning typically draws more than 20A. In a lot of cases, you can upgrade to an aftermarket radio without worrying too much about installing a high output alternator.

How to install a high amperage alternator kit?

• Slide the rubber boot and/or a piece of the smaller sized heat shrink onto the wire found in the kit. The boot will need to have the small opening trimmed off in order to slide back over the heat shrink and ring terminal after installation. • Strip about ½” of insulation from the large gauge wire from the kit.

What kind of alternator do you need for a marine engine?

Alternator for Indmar Engines by Arco®. What can be more fun and rewarding than boating on the open waters? This is an excellent solution for your boating needs. This product is great for use in all marine applications. It will satisfy… Alternator for Marine Power Engines by Arco®.

When to replace ground straps for high amp alternator?

When you install a high amp alternator, or when you have someone else install it, you should consider replacing both the ground straps and the power cable that runs from the alternator to the battery with heavier gauge cables.

How do you disconnect an alternator from an engine?

Begin by removing the dust boot from the main power terminal to expose the main power wire. If the wiring is difficult to access you will be able to disconnect it once the alternator is loose from the engine. All alternators are designed with a main power cable (large gauge) that is connected directly to the battery for main charging purposes.

Do you need to remove serpentine belt to change alternator?

As you loosen the bolts, the alternator will slide in the bracket under the tension of the belt. You may not need to remove the serpentine or accessory belt if it’s not damaged.

Is it easy to remove an alternator from an engine?

Since the typical alternator is bolted directly to the outside of the engine block, removing and replacing one is relatively simple in terms of labor. If your engine is equipped with a serpentine accessory belt, you’ll just need to release the pressure on the belt tensioner and then remove the belt.

As you loosen the bolts, the alternator will slide in the bracket under the tension of the belt. You may not need to remove the serpentine or accessory belt if it’s not damaged.

How big of a socket do you need for an alternator?

These will often require a 14mm or 1⁄2 inch (1.3 cm) socket, though you may need to try others. As you loosen the bolts, the alternator will slide in the bracket under the tension of the belt. You may not need to remove the serpentine or accessory belt if it’s not damaged. Inspect the serpentine belt for damage.

What kind of wrench do you need to replace an alternator?

Unscrew the bolt holding it in place and pull it from where it’s connected. The bolts will likely require standard sized sockets or wrenches in American made vehicles, and metric in most foreign applications. The only other cable running to the alternator connects to a harness, so it will be easy to identify.

What was the problem with my alternator going out?

I was thinking that the problem was probably the alternator and as I was trying to get to my house the instruments began to go out. First the tach, then the speedometer, and then the accelerator pedal was unresponsive. I was able to limp for a little while, but it eventually totally quit.

What to do if your alternator is over charging the battery?

Ask an assistant to start the engine and hold engine speed at about 1500 RPM. Measure voltage across the battery with your DMM. You should get 0.5 to 2 volts higher than base voltage. If you are getting more than 2 volts above base voltage, most likely your alternator is over-charging the battery or the battery is faulty.
