  3. A compact car with a 35-amp alternator can accommodate around 150 X 2 watts of power, while a Sport Utility with a 145-amp alternator can handle a 600 X 2 watt system. A capacitor can help if your system is drawing a little too much power
  4. Although alternator manufacturers, rebuilders, and suppliers typically refer to the rated output in promotional materials, both the ISO and the SAE require a format of IL / IRA VTV, where IL is the low, or idle, amperage output, IR is the rated amperage output, and VT is the test voltage
  5. Others say alternators cannot sustain that amperage for long and, regardless, it would be harmful for the car battery to charge it at 80A. If the latter, which seems reasonable, is true, then is it fair to say that an alternator isn't really faster than a typical Noco, Optimate, Ctek, Black & Decker charger, which charges in the 4 to 8 A range

The correct ampere output from your alternator is important as amperes are the current that powers the electrical items in your car. Items such as heater-fans, wipers and headlights use high amperes and, when you turn them on, your alternator has to adjust its output to meet the energy requirements Necessary High Amp Alternator Electrical System Modifications . Although the individual electronic components in your car won't be damaged by a big alternator, there are two things that might be: the alternator power lead and the ground strap or straps When the engine is running, the alternator will typically put out between 13.8 to 14.8 volts. How much voltage does a car alternator produce? The alternator is designed to keep the battery charged to at least 12.55 volts, with a maximum of approximately 14.5 volts. The amperage output is usually listed as the maximum output of the alternator

What Amperage Alternator Do You Need? Determining the alternator amperage required is the current draw, plus any future accessories you plan to add. Each accessory will have drastically different draw: an electric fuel pump can draw from 3 to 8 amps while a high-power audio amplifier can pull as much as 70 amps or more Alternator Upgrades - Upgrading is obviously a very important part of the car world, and the biggest growing segment of adding performance is now adding electrical components to early muscle cars Most factory alternators are rated at 65 to 100 amps and are capable of handling your vehicle's basic necessities, such as headlights, gauges, fuel pumps, A/C, etc. These alternators also typically come with a 10 to 15 percent reserve to handle additional accessories

Car alternators are rated to generate power at ~12V DC x some number of amps. They don't usually have a wattage number, but you can calculate it this way = 1500W / 12V = 125 Amps Therefore, you need an alternator that will produce at least 125 Amp.. Js Alternators began building high output alternators in 2013. Our units range from 240 to 390+ amps, each one created custom! We deliver nothing but outstanding reliability to our customers.

Receive a Quot I have 4 questions I would like to ask. 1: As stated, I will be running 3 AudioControl amps (class D) for a total of 700 watts RMS. The car has a stock 175 amp alternator and I am going for sound quality and not thumping volume (I am in my 50's). Do you think the Big 3 is necessary For some alternators, it's normal to see as low as 13 volts. For some, a constant 13.6 volts is an indication of a problem. For others, it's normal to see as high as 16 volts for long stretches. Still, it's perfectly normal for others to see the alternator not charge at all intermittently

Check the alternator gauge. If you have a volt/amp gauge, it will read the alternator output for you. Run engine at 2,000 rpms for tests and turn on the blower fan for the AC or Heater, the headlamps, and any other accessories that put a strain on the alternator, and watch the gauge to see if it decreases voltage or amperage Let the engine idle at around 1200 rpm. Check your car's manual or parts manual to see what your alternator's maximum amperage should be. The amp reading on your meter should be near the maximum output. A 90-amp alternator will output approximately 88 amps. If your amperage is too low, then you probably need a new alternator [source: 2CarPros]

alternator can only be taken at the shaft of the alternator. Thus, idle amperage is calculated at 2,400 alternator RPM. On a street vehicle, the average pulley ratio is 3:1, meaning that 2,400 alternator RPM is equal to 800 engine RPM. TIP: With a hand held voltage meter, check the voltage out of the back of your alternator A high-amp alternator's output can be negated by a charging wire or cable that is too small to handle it. The more amperage an alternator produces, the bigger the cable required. A 140 amp alternator, for example, requires a cable from 2-gauge to 00 gauge depending on the length (refer to the Charging Cable Gauge chart in the story) The alternator in your car is designed to generate voltage at prescribed amperage which is designated by a voltage regulator or vehicle computer. This electrical energy feeds the car's electrical system and to recharge the battery which keeps the vehicle operating properly I will show you how to test an alternator the right way for voltage and amperage without using expensive amp meters. We will make a homeade shunt (amp clamp..

An old car alternator can provide one of those ways! In a vehicle, an alternator is used to charge the battery. As such, once it begins to produce electricity, it can keep itself moving without any additional work. Here is a quick project that will give you the ability to use an old, working alternator as an alternative source for energy A small car alternator is rated about a 60 amps maximum. At about 2000 rpm the alternator produces about half this maximum, so at engine idle the alternator is charging well. Efficiency peaks at around 3000rpm, ie 50 amps, and will only give small increases over this, regardless of the rpm My car alternator runs at 16 to 16.5 volts when I hit the gas, and 15v idling. This is scaring me and a new one is too expensive. It could be my computer or pulleys in the wrong too so I can't risk buying a new one and still having the problem Be sure to evaluate the cable between the alternator and battery to ensure it can handle the increased amperage too. Car manufacturers size this cable to act as limiting protection for the alternator in case of excessive current draw from a bad battery cell. Upgrading the ground wire is also needed if the alternator is upgraded to a higher output Just a short series of 2 or 3 videos showing the process to tear down and modify your own alternator into a 320amp unit!If you have any questions or comments..

The word amperage (AMP) happens to be a word used to describe the rate in which electric current flows. One of the best ways to know the problems of the alternator is to examine the base and have an idea of the AMP the alternator generates. For you to know how to find alternator amperage, you need to have an understanding of how AMPs and volts. 13.5 volts is the bare minimum. Under that and the car installation and battery isn't getting enough electric power. Over 14.5 volts can cause serious damage to the alternator and car battery. After taking the voltage output reading, remove the tester cables from the battery poles and remove the multimeter. Close the battery casing-holder Very few Car Alternators will actually Output 100 Amps, for any length of time, and the ones that will, are very expensive. Car Alternators are notoriously inefficient, and subject to Overheating, easily, should you try to get their Rated Output for any Length of time. Marine Alternators are usually better choices 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. Each car's audio and internal running system far differs from each other

Alternators only produce enough amperage to supply the car's electrical component's requirements. An alternator rated at max 200 amps may only produce 30 amps at a given time. Voltage is a.
