Where can you have your alternator tested?
You can test it your self. Start the car might be pain in butt if alternator is really dead if so let car sit for a little while and charge it self up. Also you can knock on alternator with a happer bunch of dust will fall out and it will get you enough time to drive for few day to go get new alternator and install it without car breaking down. Anyways start the car, then disconnect the negative wire on the car if it dies the alternator is dead if not then alternator is good.

Start the engine, while the engine is running, remove either battery cable. It should stay running, if not, possible bad charging system . Or take it to auto zone. They check them for free NEVER EVER disconnect a battery cable while the engine is running unless you like your computers fried. …Here's a link to the proper way to test: http://free-auto-repair-advice.blogspot.com/2007/09/avoid-bogus-alternator-test.html Saying again, never ever disconnect a battery or alternator with the engine running. The resultant voltage spikes can fry electronics, the alternator diodes can be overloaded and fried...bad things can happen. The don't ALWAYS happen, but why risk $1,000's of dollars in damage when there are correct ways to test your alternator. One simple way is at night star your car, turn off all electrical accessories, turn on your high beam head lights and point your car at a wall where you can see the reflected light well. Notice how bright they are. Turn off the car. If the lights get brighter, odds are very good your alternator is bad/weak. (MORE)
Null hypothesis is whether there is a difference or not. Null hypothesis (H0) is a stated assumption that there is no difference in parameters (mean, variance, DPMO) for two or more populations. According to the null hypothesis, any observed difference in samples is due to chance or sampling error. … http://www.leansigmamart.com Starting with understanding the DMAIC method, with out this you are never going to have successful results.

Answer . If it's not cranking at all, it could be the keyswitch, a bad connection somewhere, the starter or the neutral lockout switch.
Answer . \nTake it out, and to the nearest Autozone and they will test it free of charge..
Connect a voltmeter across the battery terminals without engine running reading should be around 12.8 With engine running reading should be 13.8-14.2 if you are getting these numbers alternator is charging battery
Answer . Either bring to auto parts store for checking or. Use a voltmeter. With engine off and a fully charged battery reading should be around 12.8. With engine running and a good alternator voltage should be 13.8-14.2
Answer . Either the alternator/regulator has situation dependant problems such as opens with heat or vibrational malfunctions or there is a problem with an internal charging control in the engine computer
Yes, click on the 'Centre for alternatives to animal testing' link further down this page.. There are sophisticated, non-animal test methods available today, which range from cell and tissue cultures to computerized "structure-activity relationship" models.
Pull the hot battery cable off of the battery if the alternator is bad the engine will stall out.. 12/07 If you have the unit out, run it down to your local parts dealer (probably shouldn't say their name) and they can bench test it for you. Most of these places will do it for free in hopes of sell…ing you a new one. If you have the older-style (pre-electronic) system, it's as easy as having the car idling, connecting a voltmeter to the battery, then (here's the scary part) connect the large post on the alternator's back to the small post. It's best to do this with a medium gauge, insulated test jumper. This, in effect, forces the alternator to put out to its maximum. Do NOT rev the engine at all, unless you're due to replace every light in the car that happens to be on during the test. Assuming all your connections are clean and tight, you should expect the voltmeter to display at least 14.5 volts. Keep in mind that a battery that's anything but fully charged will skew your readings, but you can still compare the before and after numbers while connecting the jumper. (MORE)
no, as animals are still animals and are equal to us so what gives us the right to take innocent lives away. If we killed another human being then we would be locked. Dear Sir. I think you are very right. SPIFFING!!!!!!!!!!!!!!!!!!
simple useful alternator test - with the car running at idle and no accessories, lights, etc. on. Disconnect your positive battery cable. the car should stay running if your alternator is functioning correctly. If it is, leave your battery disconnected from the alternator for the night, or for howev…er long it has been taking to drain the battery. Reconnect in the morning and try to start it. Often alternators fail because a strain is being imposed on them by a battery short. It's good to replace both at the same time. (MORE)
Start the car and rev it to at least 1500RPMs. Use a voltmeter to test the voltage across the two battery terminals (under the back seat). If it tests out at around 13.8-14.5 volts the alternator is working. If it tests out at 12.6 volts or below the alternator isn't charging. If it tests out …above 14.5 volts the alternator is charging, but the voltage regulator isn't working correctly. (MORE)

Many auto parts stores will test it for you for free! They do it while it is on the car and the car is running.
Simple just disconnect the negative wire while your car is runing if car dies then alternator is bad and not doing any good to battery so alternator needs to be replaced. Answer 1 If you have a major chain auto parts store nearby, it would be easier to go there as most of them have the proper tes…t equipment and will simultaneously test the alternator, battery and related circuits for free. If you want to test it yourself, you will need a volt/ohmmeter [also called a VOM]. With the VOM selector switch set to the 50 volt DC Scale , and the engine running, touch the negative [black] probe of the meter to the negative post of the battery [black cable attached], and the postitive probe [red] of the meter to the positive terminal [red cable attached] of the battery. Depending on the type of vehicle, charging system, and some other factors, the meter voltage reading will vary. However, the meter should read at least 13.5 DC volts minimum to about 16 volts maximum. If you have set the meter selector and connected the probes properly, and the indicated voltage is within this range, then the alternator is working properly. (MORE)
Any Auto Parts store can check the charging system for you. Testing the alternator is simple and basic. You need to check the voltage and amperage output. The voltage is easy enough to check with a voltmeter. If the voltage is between 13.5 and 14.5, engine running, it's a good bet the alternator is …good. To check the amperage output, you'll need some special equipment. You'll need an ammeter and a load tester to check the amperage. I would let an Auto Parts store run that check as they have the equipment. (MORE)
\nAlternatives for Testing\nAlternatives to the use of animals in toxicity testing include replacing animal tests with non-animal methods, as well as modifying animal-based tests to reduce the number of animals used and to minimize pain and distress. Non-animal tests are generally faster and less ex…pensive than the animal tests they replace and improve upon.\n. \nTo date, several non-animal test methods have been formally validated and accepted by some countries as replacements for an existing animal test. Examples include:\n. \nâ¢ An embryonic stem cell test, using mouse-derived cells to assess potential toxicity to developing embryos, has been validated as a partial replacement for birth-defect testing in rats and rabbits.(6)\nâ¢ The 3T3 Neutral Red Uptake Phototoxicity Test, which uses cells grown in culture to assess the potential for sunlight-induced (âphotoâ) irritation to the skin.\nâ¢ Human skin model tests such as the validated EpiDermâ¢ test, which has been accepted almost universally as a total replacement for skin corrosion studies in rabbits.(7)\nâ¢ The use of human skin leftover from surgical procedures or donated cadavers can be used to measure the rate at which a chemical is able to penetrate the skin.\nâ¢ The use of a clinical patch test in human volunteers, which can confirm that a chemical will not cause irritation or allergic skin reactions.(8)\n. \nFor more detailed information about non-animal test methods that are available or under development, visit ECVAM.jrc.it and StopAnimalTests.com.. This is, ultimately, a question of ethics. This ethical question is one that causes many to question what they think is "the right thing to do" and some may conclude that there is no alternitive to animal testing - some may conclude that the alternitive is not very nice! In the end, animal rights activists may not condone animal testing for the sake of human progress, but on an indivual and personal leverl, each and every one of us would know someone who would benift greatly from scientific progress made possible only by animal testing - people such as Peter Singer has discusses the ethics of animal testing, and animal rights in great deal. Singer basis his discussion around the fact that animals interests, wellbeing and consciousness should be taken into consideration and not completely ignored by people who would use them, eat them, exploit them and kill them for many reasons. As for your question - alternitives to testing on one living creature are obviously to test on another living creature - perhaps considering the animals cannot and do not volunteer themselves, the alternitive (ie human beings) can.

I pulled the negative cable from the battery with the truck running and the engine quit. Is this a test to see if the alternator needs to be replaced?
The fastest way to test is to start the car with the car at an idle remove the positive battery cable if the car stays running the alt. is normally o.k just make sure you have all lights and heaters on. Or take the car to a shop and have them load test the alt.
put a voltmeter on the battery and test voltage, then start the cycle and check again. A battery at rest should be at about 13 volts, with the engine running it will be at 14 or above. to be sure disconnect the positive battery terminal while running, if there is still good volts there, or the e…ngine does not die it is ok.

Easiest test is to use a voltmeter. Engine stopped , voltage about 12 volts Engine running, voltage about 14.7 volts.
While the engin is running remove the negative side of the battery. If your car dies, your alternator is probably bad... Of it it wasn't when you started, there's a good chance it is now. NEVER disconnect the battery or alternator while the engine is running. You can fry alternator diodes,… computers in the car, electronics you have installed, pretty much any sensitive electronics can be damaged or destroyed. Take your car to get it checked.

It checks many things, connections, belt, and voltage regulator. I have never checked one with a load test. On a modern car or truck, never ever disconnect the battery from the alternator with the motor running to check the alternator. It can burnup a lot of electronics instantly.
Cortisone/Predisone will give you a positive. Have a current prescription for the tech, so they can test specifically for anything in excess of your legal therapeutic dosage.
Check the gauges, if the car is equipped with them. If you have a volt/amp gauge, it will read the alternator output for you. 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. As a rule, if the voltmeter is higher when the engine is running then when the engine is not, you can confidently assume that the alternator is charging.Check it at the battery with the engine running. It will show at least 13.5 volts if the alternator is good. If these values decrease when you turn on electrical accessories, the alternator may be weak.Listen to the alternator while the engine is running. If there is a problem with the bearings you may hear a squealing sound coming from the front of the car, which becomes louder with more electrical accessories using power at the same time.Feel the alternator after the engine has run a few minutes and you turn the engine off. If it is very hot, you may have wear to the bearings or the insulation on the copper windings may be breaking down, an indication the part may fail soon. To actually measure the charging current on a cheap modern digital volt meter:Set meter to most accurate voltage range, with the engine off measure the voltage between chassis and chassis connection at the battery, this should be nearly 0 volts, now turn the headlights on, the headflights will draw about 10 Amps and the volts drop across battery earth to chassis will show about 50 millivolts dependent on the resistance of the earth strap.Remember 50mV is proportional to 10 Amps.Turn the headlights off and start the engine, the meter will show the charging current and this will be in the opposite polarity as the current will flow in the opposite (charging) direction.for example if the meter shows 100mV the alternator will be charging at 20A.turn the headlights on and you will see the charging current to the battery reduce as half the alternator current goes into the lights.

A lot of auto part stores will test them for free. Give them a call. Your alternator can only be tested when the engine is running, therefore you will have to get a boost or use a battery charger for the battery. If you have a voltmeter, test at the battery terminals with engine still running, if …you get 13.5 to 14.7 volts, the alternator is charging. In some cars, the voltage could go over 15 volts if the battery is close to dead (right after being boosted), but the voltage should go back to normal as the battery gets closer to fully charged. Turn off the engine, the voltage will go down to 12.5 volts if the battery is now charged, lower if is not. If there is no change, the alternator is not charging. KGP484 (MORE)
First, get a volt meter. Test the voltage of the battery before starting the car, then start it and see if the voltage increased. You should see a jump of about 3-4 volts.Alternatively, if the car has a manual transmission, you could tow the car in gear (very slowly, about ten MPH in first) with the… engine off and the battery removed and test to see if the alternator is generating power. Without the battery it should only make about one or two volts, but you will be able to notice it on a voltmeter. (MORE)
1st you start up the car. Hook up a voltmeter to the battery, and put a load on the battery as the car is running (have the lights on, radio on, high beam on,...) after you put a load on the battery read the voltmeter. if it goes below 12 the alternator is bad. It souldn't be no more than 14 volts. …you can also use the battery gauge but to be 100% sure hook voltmeter to the alternator. (MORE)
You can have the alternator tested free of charge at just about any major auto parts store. By the way, a bad alternator will not "discharge" a battery - the alternator's function is to provide the charge to the battery. If the alternator is faulty, then it is not providing the charge necessary to k…eep other components from discharging the battery. I had the alternator tested and it was charging. If the alternator has a bad diode, it will discharge the battery. I replaced the alternator and everything is fine. (MORE)
It's pretty simple, if you have access to a digital voltmeter, which can be had for as little a $5-$10 at a discount store. The voltage of 13.8 volts on any standard 12 volt automotive vehicle is about the average, when an alternator is properly functioning, while the vehicle is running. If it… measures over 14 volts, the voltage regulator is shot. They are mostly attached to the alternator these days, but can be remotely mounted to the firewall in older vehicles. To test the alternator, just attatch the meter leads to the battery terminals. Red for positive, and black for ground. Make sure the meter is set to the Volts DC Scale,so you get a proper reading. Check the voltage with the vehicle off, which should read around 12 volts and while the engine is running, around 13.8 volts. (MORE)
There are a number of ways to test an alternator, 1,Set your voltmeter to DC most preferable set the meter to 20volts.2,with the engine running, disconnect one of the battery terminals from the battery head. 2,connect the voltmeter to the battery terminal wires and take your reading.

Objective: . To determine the direct & quadrature axis reactances of a salient pole alternator .. Apparatus: . 1. Two A.C voltmeters. 2. One A.C ammeter. 3. Rheostats. 4. A single throw triple pole switch. Theory: . The unsaturated values of Xd and Xq for a 3-phase synchronous machine… may be. found by applying low values of balanced voltage to its armature, and driving its. rotor mechanically at a speed differing slightly from the normal synchronous speed,. the field circuit being open. The rotating armature m.m.f axis gradually changes, on. account of the ' slip ' between coincidenc4 with the polar & interpolar axes. successively. The reluctance of the magnetic circuit varies cyclically between an. upper & a lower limit, and the armature current consequently changes in the reverse. sense. The ratios of applied voltage to armature current gives the synchronous. reactances, using minimum ratio for Xq and maximum for Xd. Xd has the same. value as would be obtained from the normal no load and short circuit tests.. Procedure: . 1. A coupled D.C motor very near to synchronous speed runs the salient - pole . synchronous machine. If the synchronous speed is 1500 rpm, the set is run at. 1750 rpm.. 2. The stator of the salient pole alternator is supplied from a low voltage (10-20. Volts), 3 -phase supply. The supply frequency is more than 50 Hz as the. supplying alternator is run at 1750 rpm.. 3. The field is kept open and the maximum and minimum deflections in the. ammeter (to read the supply voltage) are read.. 4. Xd, Xq are calculated.. Results: . Xd = Maximum V/Minimum I. Xq = Minimum V/ Maximum I. Discussion: . 1. The alternator should not be run at exactly the synchronous speed, for then. instruments will give steady deflections. The stator voltage must be capable of. close adjustment. The slip must be very small. Otherwise the measurements will. be in error on account of eddy currents in the pole faces or the damper windings.. Page 2 . If in the experiment, the slip is very large, and cannot be adjusted to a smaller. value, he measurements are liable to error.. 2. The slip tends to pulsate because of fluctuation of torque with the relative pole . positions with the result that there is a tendency for Xd to be underestimated. (MORE)

Yes you can take negative off on all cars and test it if it dies alternator is bad if car keeps running then its good. In older (not computer controlled) cars you can, but on some newer (computer control) cars is not recommended. Some newer cars will turn off even if the alternator is working goo…d.

One can test an alternator while it's still in the car as long as the car runs. Use a volt meter across the battery terminals while the vehicle is running. The volt meter should read 13 to 14 volts in a 12 volt system. If it's lower your alternator isn't charging sufficiently. Have a friend push the… accelerator and hold the car at 2000 rpms and test it again. You might try this at higher rpms as well depending on where your vehicle redlines.
