Alternator is what charges the battery. The alternator isn't putting out enough of amps to charge your battery and you will get a light or gauge reading that the voltage is low.

There is a very high likelihood that your alternator has failed, resulting in your battery not charging.A simply volt test can be performed with the car running to tell you if the alternator has failed or not.I hope I could help....

If battery is good, then your altenator is bad.

SOURCE: 1996 mitsubishi eclipse doesn't start when turning

check for voltage at the small start wire on the starter when cranking the engine--you will need someone help. If there is no voltage you may have a bad neutral safety switch ,which is on the trany shifter.you have an automatic trans i assume.
If so try putting in neutral when cranking.

SOURCE: battery light was flashing on

There isn't much to the charging system on any vehicle. The belt spins the alt copper binding and creates eletrical current. That current goes directly back to the battery. The other wire goes to the gauge in the dash. I would replace the alt. If you said it was intermittent and it tested good at the rebuild shop who is to say that wasn't one of it good times? Easy way to find out how good it is. While the car is running unhook the possitve terminal from the battery. If its good the car will stay running. If it isn't the car wont.

SOURCE: 2002 sonata 2.4l battery dash light on. replaced alternator. Still not charging

I don't know if your car has an integrated regulator or not; some house the regulator in a section of the alternator case, others mount it remote from it. The regulator monitors the load and battery voltag,e primitively but effectively, and controls the current flowing through the field winding of the alternator to ground, changing the magnetic field intensity and consequently the voltage output of the alternator. The 'hot' end of the field is internally connected to the + output, the 'cold' end is controlled by a transistor inside the regulator which, in turn, is controlled by circuitry monitoring the system voltage.     Some alternators can be tested by sticking a wire through a specified opening, actually shorting the controlled end of the field to ground briefly, while monitoring the voltage across the battery, doing this though for seconds only. This essentially bypasses a suspected defective regulator; this causes the output voltage to rise instantly to its maximum of ~17 volts if the alternator is OK.
I don't recommend poking a wire at random into an available opening so having a service manual (Haynes-Chilton) would be nearly mandatory.

When i stopped all dash board lights came on and now wont start and has no power to anything


When vehicle stalls, the dash lites may come on.
Make sure battery has a full charge, battery connections all good. Make sure charging system is working properly.
Use a test lite and check voltage to fuse circuits in fuse box. Some fuses circuits are hot all the time, some go hot with the key on. Right now, I can't tell if you have problem with battery--battery connections--charging system--fusible links--ignition switch or what? You need to do some testing. Let us know what you find?

In a 2002 Grand Caravan What dose the Battery looking dash light mean when it comes on and stays on? Has a new battery in it.


Hi there,

If the battery dash light remains on, it is a strong indication that you have a recharging issue. The new battery will only work if the alternator keeps it charged well. My suggestion would be to take your car to a mechanic and have your alternator tested.

Good luck.

Alternator & dash light


ok , i bet you didnt test all fuse. in dash and under hood, i bet
fuses that look good, can be bad (hair cracks)
use and ohmeter, 0ohms good, infinity bad.
if you have 12v and the Cig lighter and the dash is dead.
then the fuses are blown.
log in to alldata.com and look, all the drawings are there.

Dash lights won't work and alternator doesn't appear to be charging battery. All visible fuses are good


The alternator needs power from the battery to energise the rotor, so without the dash lights the alternator is not charging. Check for a fuse link near the battery. Get the dash lights on and the charging fault will clear. Sorry I can't be more specific as to the dash problem.

The van wont start, no lights on dash except for the seatbelt and open door light. when you turn the key it makes a click in the dash. the battery is fully charged and the terminals are tight.


How do you know the battery is good, fully charged may not be the case if the battery has a failed internal post connection. Have the battery load tested at a shop or a parts store.

Service battery charging system message came up on the dash. Dash lights have been flickering recently


Stop by any good parts store and have your charging system tested and your battery load tested. Most will do it free. Sounds like an alternator on it's way out or a stretched belt, but have it tested before throwing parts at it.

I have a new alternator, new battery but will not charge . dash gauge shows low charge.


To verify if gauge is accurate, take to local autozone (or any good parts store) and have them do FREE charging system test and to load test your battery - both are free services.
