Hi:
often, these sorts of things are hard to find. It is really common for a bad alternator to cause that sort of thing too.

I don't know what sort of equipment you have available, but a good plan is to get the alternator checked, and most auto parts stores will do that for free.
If it checks ok, then disconnect a battery cable, and put an amp meter in the circuit, and see how much current is being drawn on your car. There should be a small amout, but if it is more than a few milliamps, you can start pulling fuses out of your fuse box, one at a time, till you narrow it down to a certain circuit that is drawing too much.!

My 2005 Sebring 2.7 v6 won't start. It acts like a bad ground, any clues?


Wiring CAN be a problem, but it is not the first thing to check. When cars fail to start but you hear "something" (click), the first thing I suspect is the battery. You say the battery is "good", but you don't say how you determined this. Simply the fact that accessories work doesn't give the battery a clean bill of health. The normal accessory load for a battery is less than 50 amps. It can take more than 200 to crank the engine, especially on very hot or very cold days. Since you only get a "click", and yet the trip computer dims out, this indicates to me that the battery is working very hard but is not achieving enough power to start the car. Do this: get a voltmeter and check the battery voltage at the battery terminals. Do this with the ignition off. A fully charged, good battery will be at least 12 volts. Most batteries have 8 cells in them, each produces about 1.5V electricity. If you are reading, say, 10.5 volts, you most likely have a dead cell in the battery. This will not affect accessories, but will have extreme affect on starting, as the available current is reduced exponentially. Jump boxes are great, but if the battery is dead enough, the box will be working harder on the battery than on the starter and you will get the same results. I've had situations where a battery was so bad that hooking a running car to it for jump a start stalled the running car! If your battery is more than 3 years old, this is the first thing to suspect....but a dead cell can happen to a battery of any age. Vibrations cause the internal plates to break loose and cause dead cells.

3-yr old battery went dead in my 2002 chevy S10 pickup


Yes, it sounds like your alternator is short circuited internally. Replace alternator with high quality rebuilt unit
how does the alternater works
Alternator and Charging System A battery is needed to power the operating system of your car. Once the vehicle is running the battery is charged by the alternator which is driven by the engine. While in operation the alternator creates electricity, about 13.6 to 14.3 volts, and recharges the battery to its original state of charge. The alternator is one of the hardest working electrical components in your vehicle. When your vehicle is running the alternator is busy creating electricity to provide the engine and the car accessories with needed power. When the car is not running and your battery is severely discharged some electrical components may still operate or operate poorly. Typically, these components are designed to operate properly at 12 volts; if the system voltage is low it can cause erratic symptoms.
to check out how the alternater looks .
When jump started a severely discharged battery can cause the alternator to overload and internally fail. If this occurs replace the battery before replacing the alternator. This will help prevent a second alternator failure. Most vehicles use a multi-ribbed belt connected to the engine to rotate the armature inside the alternator. If the belt fails it should be replaced immediately. Belt tension should be taught. If it isn't, check the belt tensioner. It may need to be replaced or the incorrect size belt may have been installed. Either of these conditions can cause the vehicle to stall and not restart.

Code p0562 on a 2004 Kia Spectra


Hi there:

P0562 KIA - System Voltage Low
The battery supplies electricity to the ECM even when the ignition switch is OFF. This electricity allows the ECM to store data such as DTC history, freeze frame data, fuel trim values and other data. If the battery voltage falls below a minimum level, the ECM will conclude that there is a fault in the power supply circuit. The next time the engine starts, the ECM will turn on the MIL and a DTC will be set.



Possible causes:

- Loose or missing alternator drive belt
- Faulty alternator
- Battery defective
- Open or short system voltage circuit


Tech notes:
Start by recharging or replacing the battery.

The P0562 code is detected when the battery voltage detected by the ECM is less than a calibrated value



Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Slow engine start
- Low battery power


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

What does check engine code P-0455 and P-1684 mean?


P1684 - Battery Disconnected Within Last 50 Starts

P0455 - Evaporative Emission Control System Leak Detected (no purge flow or large leak)
This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

Symptoms: You likely won't notice any drivability problems.

Causes: A code p0455 most likely means one or more of the following has happened:
A loose or improperly affixed gas cap
A non-conforming gas cap (i.e. not factory/original brand)
Other leak or damaged piece in EVAP system

Possible Solutions: With a p0455, the most common repair is to:
Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
Otherwise, replace the gas cap, and/or
Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary


Test and check it. Hope this helps.

The battery in my 2001 A6 2.7T won't hold a charge for more than a few days. The battery is approximately 5 years old. The voltage meter shows a charge of 15 or higher when the car hasn't been run in a few...


It looks like your charging system is operating properly so there are two possibilities. The first is that there is a large drain on your battery while the engine is shut off. Possibly a light left on somewhere like the trunk light or the glovebox light staying on when it should be off. There are other drains that may be occuring which will need a test meter and time to discover. The other likely cause will be a dead cell in your five year old battery. Have the battery tested and you will find that one or more cells are bad, causing the battery to drain. A five year old battery has about used up it's time in your car. good luck!

Battery goes dead after several days, have tried


Connect the meter, then pull fuses one at a time until the current draw goes away.

You have now isolated the circuit that is the culprit. Troubleshoot that circuit and you'll find what is causing the problem. I would suspect there is a light staying on somewhere (engine light) or possibly ABS pump (if truck has ABS brakes). Maybe dash lights are on all the time.

Let me know what you find, or if you need more help.

MY BATTERY IS DEAD ALTHO IT IS RELATIVELY NEW. A MECHANIC SAID IT WAS''LEAKING.'' WHAT DOES THAT MEAN AND HOW CAN IT BE FIXED??


New? then, go to the dealer where you bought it. It must be still under warranty. It's not supposed to be
leaking since it is new. Otherwise, you have no option
but to buy another.

I have a 2003 dodge ram 1500 with a V-8 4.7 engine and my check engine light came on with a P0456 code and I have been told that it could be the gas cap, I have checked it and it seems fine but should I...


The leak in your evap system is very small at .020. It is more than likely a small split in a hose somewhere. The cap is probably ok, we rarely find a bad one. If it is a small split in a hose it will only get larger over time. Here is the factory info on the code. We have found that alot of these leaks are from a small hose on the evap canister under the vehicle, but with out looking at your vehicle it is hard to say. If the leak goes away or is no longer large enough to be detected, your light will go out after a few days. These leaks are emmissions related and will not effect the integrity of the vehicle. I would have it checked and corrected if the light stays on at your convienience.

Symptom List:
P0442-EVAP LEAK MONITOR MEDIUM (0.040) LEAK DETECTED
P0455-EVAP LEAK MONITOR LARGE LEAK DETECTED
P0456-EVAP LEAK MONITOR SMALL (.020) LEAK DETECTED
Test Note: All symptoms listed above are diagnosed using the same tests.
The title for the tests will be P0442-EVAP LEAK MONITOR
MEDIUM (0.040) LEAK DETECTED.
When Monitored and Set Condition:
P0442-EVAP LEAK MONITOR MEDIUM (0.040) LEAK DETECTED
When Monitored: Immediately after a cold start, with battery/ambient temperature
between 40° F and 90° F and coolant temperature within 10° F of battery/ambient.
Set Condition: If there is a leak larger than 0.0409 and smaller than 0.0809 in the
evaporative system.
P0455-EVAP LEAK MONITOR LARGE LEAK DETECTED
When Monitored: Immediately after a cold start, with battery/ambient temperature
between 40° F and 90° F and coolant temperature within 10° F of battery/ambient.
Set Condition: There is a leak larger than 0.0809 in the evaporative system.
P0456-EVAP LEAK MONITOR SMALL (.020) LEAK DETECTED
