Can i use a higher amp alternator?
If your vehicle is not a police vehicle, replace the alternator with the 105 amp alternator. The police package alternator has more amps due to the fact that it has to compensate for the extra load a police cruiser needs: lights, siren, dashcams, etc. And yes, if you get an alternator that generates more volts than necessary, it would most likely fry your battery.
Is it better to have a high-amp alternator for my home, or should I use a conventional high-volt alternator?
I don’t think you understand the question. What voltage do you need for your home? 115Vac (USA), 230Vac (Europe), whatever you need is what you should get. The amount of current is secondary. What are you going to do with the power? Use for lighting? Air conditioning? Big difference!How are you operating the alternator? Wind Power? Gasoline? Natural gas?Also do you know what QUALITY of power do you need? Are you going to use it to operate a motor; then you do not need an inverter type, but if you are going to operate a computer or other sensitive electrical equipment, then you will need a more expensive inverter type.There are a lot of variables. I have an inverter type 115Vac at 2000 Watts (17 amps) to make sure I have enough power for the freezer, refrigerator, furnace and computer. Not enough to run the whole house. Depends on what you need and how much money you want to spend.In a REAL emergency you will not be able to buy gas since the gas pumps will not be operating, if power is lost. Natural gas may be a better choice. All depends on what you need.Hope this is helpful!
Can I install a higher amp alternator on a stock truck? It’s a 350 5.7 engine.
I suggest you search an online catalog or 2 for your exact make and model vehicle / engine alternator. Very often there will be more than one listed. Compare the results to the rating on your existing alternator. If a higher capacity alternator is available it usually will be a bolt on replacement. Next check the drive belt and see if the part number is different. If so the mount position or alternator physical size may be different, and you would want to be careful. Sometimes there is not enough “belt wrap” around the alternator pulley to drive a larger alternator without slipping issues. What happens when a v-belt slips. Early 80s Chevy 350s had trouble with this. Rule of thumb is 1 v-belt per 60 amps. Above that, can compromise belt life.
Will a High Output alternator use more gas because it's harder to spin?
I have a 2001 Ford Crown Victoria with the P71 police package. The car is supposed to come with a 220 amp alternator. It was removed and there is a 135 in there now. It is dying. If I get the 220 amp alternator, does it use more gas? If so, how much? It does require a stronger pulley for the motor, and weighs two pounds more. Some people say it has heavier windings to turn? Is this true? Basically, what I need to know is whether a HO alternator (that is actually specified for my vehicle) would result in a loss (even a little) of gas mileage.
What kind of battery for my system?and how many amp alternator?
http://crutchfield.custhelp.com/cgi-bin/... Your car's alternator ampere rating determines how powerful an amplifier you can install. Multiply the ampere rating by 40%, and you'll get a rough idea of how much reserve current capacity your car's system has. Next, you'll need to calculate the approximate current draw of the amplifier you're considering installing. To calculate the current draw of an amplifier, multiply the number of channels by the RMS watts per channel (a 2 channel amp rated at 300 watts RMS per channel would be 600 watts). Double it to account for amplifier inefficiency (600 watts X 2 = 1200 watts), then divide by the average output Voltage of an alternator, 13.8 volts (1200 divided by 13.8 = 87 amps). Since the average music signal requires about 1/3rd of the average power in a test tone, divide by 3 (87 amps divided by 3 = 29 amps). The result is the amplifier's approximate average current draw. A quick way to ballpark an amplifier's current draw is to divide the total fuse value of the amp by two. For amplifiers with multiple fuses, the rating of all fuses provided with the amp must be added together. This will likely produce a significantly higher estimate than using the proper formula. Although inaccurate, this will err on the side of safety. Finally, compare the amplifier's approximate current draw to your vehicle's reserve current capacity to determine if the electrical system can support the amplifier. If all those numbers are a bit much, here's a simpler way to think about it: an alternator capable of producing 65 amperes is usually adequate for systems up to 270 X 2 watts RMS. 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. If you want more power than your alternator can service, you will have to consider having your alternator rebuilt for higher output — or invest in a high-output aftermarket alternator. Installing a second battery won't help — that only allows you to play your stereo for long periods with the engine off. But, remember that any system playing at one-third volume is drawing considerably less current than the same system at three-quarter volume, and may not need a charging system upgrade if the volume levels are kept reasonable.
Cons of high output alternator?
There are none. A 90 amp alternator by today's standard is a pretty weak sister. The only negative aspect is the higher the amp out-put the slightly harder it will spin.
High output alternator or deep cycle battery?
Both... I have blown out a couple of alternators... One 90 amp and the other a 120..Presently I have a 120 but need at least a 220 amp..It isn't easy for the replacement in the car that I have.. The whole front end has to come off to remove or replace . If you are running a capacitor or capacitors do not go too cheap..I bought a 10 farad and it cost me quite a bit after the alternators circuit board blew and so did the cap.. The whole cap started to melt and smoke was everywhere..Car malfunction and burnt circuitry smell was everywhere..The dash lights would go out the lights ,signal and dome lights blew the transmission would not shift correctly and the master cylinder brake light sensor was burning out... Nightmare... The alternator was putting out 19 volts so the battery was swelling up and needed to be replaced. I Have since acquired an isolator 500 amp, a aux. battery (deep cycle,) a decent cap copper cabling not that cheap aluminum junk and decent components.. There is just a handful of the best no matter how good you can tweak the cheap the good will sound a bit better.. most people do not care.. Audiophiles do..
How many watts can a car alternator make?
Most alternators I see these days range from 80A to 140A output as standard equipment. V x A = W, so using the standard 13.8V, we have anywhere from 1104W to 1932W. There are special alternators people use for specific purposes that can produce quite a bit more than that too.
New 200 amp alternator, voltage still dropping!!!?
I just bought a 200 amp alternator, and had it installed right away. I'm running sounds in my car (12" Rockford Fosgate T1, Soundstream 1000watt amp). I always had problems with my lights dimming before, so i bought a optima red top battery, also did the big 3. Still dimming. So i bought a 200 amp alternator (but my installer said he could only get it to 150-160, not sure if he meant in idle though), Still dimming!!! WHAT DO I DO??!!! Also, it seemed like the dimming got a little worse after i put in my new alternator! I also notice that when i'm in idle, my voltage goes down to 1/4 the meter, which is about 11-12 volts (without bumping any music). Then as i accelerate, it goes up to 14-14.5. But still when i bump my sounds, while driving, voltage drops, and my lights dim to the beat. I'm totally confused, and i dont know what else to do! could it be my battery? Do i need a Better, High output/high amp alternator ie. 300 amps??? Please let me know of anything i can do!!!
