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.

SOURCE: truck won't start

You should check your battery cables with an ohmmeter and see if they have any resistance,they should be at 0 ohms or just alittle over,but could possibly be the starter solenoid also.I had this same problem with my Toyota last year,hard starting sometimes needed a jump and then the alt went bad,turned out to be the solenoid was shorting intermittantly.Hope this helps.

SOURCE: battery indecator light on on dash

Check to make sure that there's power from the alternator to the battery on the charge-back wire. If nothing's there, then your alternator is junk and you'll have to replace it again.

Could be your alternator. If you can get it started again. Try to have the alternator checked out.

SOURCE: I have a 1996 C180. The car is not holding charge

The battery (or IGN) indicator on the dash, when lit, indicates that the alternator is not charging.

Check the battery terminals are not corroded, and the battery +12V and earth connections to the vehicle are in good order.
Check battery electrolyte lvel is ok.

Check the battery terminal voltage - it should be 13.8volts to 14.5 volts with the engine running. Switching on the headlights should not cause any reduction in that voltage while the engine is running.

The battery will not charge significantly unless the terminal voltge is in excess of 13.0V.

If all the above test ok, and the battery discharges between daily vehicle uses you may need a new battery.

71 c10 not staying charged... new battery alternator fuses good and new voltage regulator


Maybe it wasn't running long enough to charge up the battery?
Stop trying to jump it, when you are having problems with it dying, take the battery off and have it charged. And/or buy a $20 voltmeter to see what the battery shows. If it says less than 12 volts, it is discharged, and needs charging. A good battery that is not run down should have at least 12.5 volts. A new battery that is charged should have very close to 13 volts, maybe 12.8 volts.
When you have the truck running, check the alternator for charging. You put the voltmeter right on the battery and check it again. This time, with truck running, battery should show at least 13.5 volts. That shows the alternator is working. A good alternator will put out about 13 or 14 volts-the regulator will keep it from going any higher to prevent problems, like a melting battery or electrical parts burning out.
I would say get the charging system working right, then address the problem of dying at stop lights. That could be a carburetor problem, if the alternator is working.

Lorry over heating


Sounds to me like you have a broken fan belt. The fan belt powers the alternator and the cooling fan. If it's broken you overheat and have no charging just as you are describing.

Check Charging System/told not the alternator


Check your battery connections - where the cables connect to the battery posts AND where the cables connect to the starter/main power feed and where the ground cable connects to the engine and/or frame. A poor or corroded connection can cause intermittent problems and poor charging performance.

My battery light came on and my battery dies like i aint getting a charge and when i charge the battery it starts everytime alternater is good what could it be


How do you know alternator is good?
Put in a cheap volt gauge.
Should read 12.5 normal.
Down to 10 starting.
Back to 12.5 at idle.
Up to 13.5 when engine revved up.

But battery low on water will not hold charge.
Could also have internal short.
Volt gauge will show.

Could also have something staying on, like engine or trunk compartment light?
Pull one battery terminal, and see if test light lights up across gap. If it does, even weak, you have a constant drain. Could be alternator. When diodes go bad, alternator can drain battery. Disconnect things until light goes out.

CHG Light Showing, in our 81 Corolla CS what dose this mean?


Your chg light is your charging system. It could be your alternator, battery, cables, wires etc. Generally pretty easy to diagnose with a multimeter. To check the alternator the old fashion way, you can start the car and disconnect the battery while it is running. If the engine stops then the alternator definately has a problem. This is not recommended as it is much safer to use a multimeter.

93 LX 5.0 replaced battery, ran fine then would not start


sounds like you have a good battery, get the car started put a voltmeter to wire connected to the back of your alternator. if you have at least 13.25 volts you have a good unit if any lower replace the alternator
the click sound you are hearing comes from your relay it is getting low voltage from the battery. because the battery has no juice caused by a bad alternator


hope to help shack

You alternator in under-charging that is why.

Have it serviced or you replace it. I had the same problem about a week ago and that was the way we fixed it.

2001 F350 Charging problems


actually the only thing i can recomend is to have the alternator replace again for warranty and before starting the truck charge the batteries very well with a baterie charger make sure to charge them individually because with a low batterie the alternator has to put a lot of load and might burnt again
specially with dual batterie.
