Test the car battery & the alternator supply voltage. If the alternator voltage is around 14 Volts, engine idling and headlamps low beam turned ON, then the battery is bad. After engine stopping, the battery voltage should be at least 12,4 Volts. The battery could be too old and needs to be replaced. If the alternator voltage is below 13,8 Volts then you must check up first time the alternator belt & tensioner pulley. If everything is OK, then the alternator is out of order and needs to be repaired in a dedicated workshop: weared brushes, bad voltage regulator, ...

SOURCE: battery or altenator

with the engine idling, check the voltage at the battery terminals. if its between 13 and 14.6 volts the alternator is probably ok. If its below 13V you need a new alternator. above 15V same thing.
Why did u think it needed repair? is your battery not holding a charge?

My battery light lit up on dash of my 2008. Mitsh. lancer gls cvt....what does that mean?


Altenator is not charging the system. It could be the altenator, regulator (built into the altenator), A loose wire (bad connection). There is a plug on the altenator that signals this light when a problem occurs. start the car and wiggle it or unplug it and plug it back in, this will tell you if you have a bad connection. To check the altenator you need a voltage tester.

Will altenator cause motor not to start even though you are getting fuel and spark


ALtenator runs your car while it is running and charges your battery. If your altenator is bad you car will run on the battery until it drains the battery dead. So no the altenator will not prevent you car from starting. Check your fuses.

yes ideas.your altenator may be bad,or the belts broken to the altenator. look for yourself to see.if the belts are all on,then charge your battery and take your car to an autozone or advance auto parts store and they will check both battery and the altenator for free. if both check good,which it sounds like a bad altenator to me.they will charge your battery for free also,which then,you'll have enough power on the battery to drive back home,or a close repair facility. they will not[autozone or advance auto parts] replace,remove your altenator,but they can check it while it's still on the car.if it turns up bad,they can charge your battery fully,which with no headlights on,you can drive about 25miles with your battery FULLY charged.thank you for choosing fixya.com

I'm having an issue with my car dieing. I tried the conventional jump and couldn't even get the car to turn over.? There is an indicator on the dash that the lights are on, but I can't seem to identify...


in order for the car to do conventional jump, you'll need to leave the booster cables hooked up for say, 10 minutes at least. you may have left lights on accidently.while the other car is attempting to boost yours,look for anything you may have left on,headlights,an interior light on,maybe a door left cracked open.the cold weather wreaks havoc on car batteries. your battery may need replaced. autozone, advance auto parts, both of these parts places replace car and truck batteries free.they also can check your battery to see if does need replacement.they can also tell you whether you may have an altenator thats bad, your car dieing issue may be your altenator bad,when your altenator goes bad,the car will run until the battery is drained completely. if that is the case,you can take your battery out, have it charged,then drive to a close repair shop for altenator replacement.hope this helps,and as always,thank you for choosing fixya.com

Will not hold charge


Probably a bad battery. Bring it to a parts store for a free check of the charging system and battery. They can tell you what the problem is. Either the battery is bad, or the alternator is not charging.

Alternator


well Jennifer there is a quick way to do this start the engine lift the hood and remove the positive battery cable if the engine shut's off your altenators regulator is bad. Please note that is how I have always checked them. some mechanics believe that there is a potential for a battery to explode by doing this, however i never had this happen in 25 years of being a mechanic. you should still use caution when working on a vehicle . if the vehicle doesn't shut off then your battery is probabl;y no good. another altenative is take the vehicle to an auto parts store like Oreilly's and they will test the battery and altenator for you this is free of charge. please rate this thanks
