Alternators
An alternator is an old term for electric generator that converts mechanical energy to electrical energy producing alternating current. Alternators are mainly used for recharging batteries and to power electrical loads of vehicles.

How can you test an alternator efficiency?
A simple test is to start the engine and let it run at idle. Connect a digital multimeter set to 20 volts DC to the battery. Red to + and black to -. If the alternator is good you will read from 13.5 to 15.5 volts. This tells you allot but is not a definitive test. To test it completely drive to your local auto parts store and have then test it under load. Most will do this for free.
Does 1996 Dodge Ram have generator or alternator?
It is technically an alternating current generator.
It is technically an alternating current generator.
You could have a starter going bad, the cables themselves might be bad or the timing may have slipped too far advanced. TRy this before you do anything else. Try jump starting it from another vehicle. If it still turns slowly the starter is probably bad but, then again it may still be a cable. At least you will know it is not a timing issue if it starts right up.
Can you run a 12 volt vw beetle with a 6 volt generator?
No. The ignition needs 12v to run, the starter needs 12v to crank, the bulbs all need 12v to get bright enough...
You could have a bad fuse, or a bad fusible link. However, you could have fried the computer or the voltage regulator, or any number of other things by trying that. When dealing with a vehicle younger than an 80 model, you should never remove a battery cable while the engine is running. When you remove a battery cable while the engine is running, the alternator starts charging wide open. The voltage on the electrical system can get up as high as 40 VDC! That's a little too much for the electronics in today's cars.
Will your alternator recharge your battery if you let it sit for a while?
If the engine is running and the alternator is good. If the engine is not running, no.
What is a way to check alternator car should stay running if battery is disconnected?
If the alternator is not working the battery gets discharged. In most cars a light will show on the dashboard - battery light icon, and this will suggest fault in the battery or alternator. You will need to start the car and check if it is charging the battery, and most garages will do this check for you
What is a likely explanation when an alternator is overcharging a battery?
Defective voltage regulator.
How do you loosen the alternator on a 1986 Pontiac fiero?
There are two bolts to loosen to adjust the alternator belt tension.
1st is the adjustment bolt.
2nd is the pivot bolt
It is easiest to get at them from the bottom of the engine on the passenger side rear of the engine.
What fuse controls the alternator on a 2003 Mitsubishi montero sport?
Fuse control the alternator is in engine compartment fuse box reads 100 amp and to find out alternator is good or bad disconnect your ground cable when SUV running .after disconnected and not running just kills motor down, alternator is bad .precaution do not let the ground touch the positive post cable will short your alternator needs to be replace...... hope this helps good luck Montero sports fans.
How do you install an alternator on 2003 Acura RSX?
If you don't actually know, I would highly suggest taking it to a shop.
What is an alternator commuter end?
no such thing, starters have commutators alternators have Slip ring.... or slip ring end when referring to directions
How do you test an alternator with a volt tester?
Check the voltage with a volt meter at the battery with the engine running at idle. You should read 13.5 to 15.5 volts. Any less and the alternator is not charging properly.
How much does a Volvo alternator cost?
That would depend on what year which you do not list. A phone call to any auto parts store will give you the answer you are looking for.
How rectify the frequency problem when alternator generate the power?
For portable power generation, many manufacturers now make proper 'sine wave generators" in which the voltage from the generator (generated as AC for simplicity), is rectified to DC, and then passed through some electronics to convert it into a good quality 50hz (or 60Hz) sinewave.
Because of the electronic conversion to AC, even when the generator comes under a step in load, the frequency will remain constant. But of course, the voltage may stumble a little.
I'm not sure how resistant such machines are to changes in the phase angle of the load.
A simple alternator will be entirely dependent on the load changing the motor speed.
Why is the battery light on the dash board panel light up when the air con is on?
I would imagine that there is a short circuit or a Parasitic drain on air con circuit. Often air con is ran automatically and wiring would be linked to ignition circuit.

What else can kill a battery besides an alternator?
Time. Auto batteries share one thing in common with humans - no matter how long they go on, they all die eventually. they last longer if well maintained, and with a good alternator, but they all die eventually.
What is the function of the regulator in an alternator?
To control the alternator's output voltage under varying loads.
In simple terms it regulates the voltage being sent to the battery.
What would be wrong with your truck if you replaced the battery and still get no power?
It could be anything from the engine to the connectors
Why would battery light stay on after new battery 2006 explorer?
Your battery is not charging due to a problem with the battery cables or a bad alternator.
Can an alternator stop the ac from working on a Toyota Camry?
No, it cannot. But the belt connecting them together can.
