Charging system warning light.

back in december my battery light and check charging system light came on, the car ended up dying, i had the alternator rebuilt, and reinstalled, the lights still come on after a charge, and i cant make it out of my parking lot, looked at the wiring today, all seems ok.. my fuse for my 'cd' is blown, as it was not before, wondering if maybe the megafuse needs replacing or should i trickle charge the battery for a day? my belt is ok, however there is a fair bit of gunky crap near pulleys and on the belt, but the tension is fine.

My car has 200000 kilometers.
My car has an automatic

Experienced mechanics share their insights in answering this question :
This may be a sign of a weak battery or a failing voltage regulator. As you may know, the alternator is responsible for charging the battery while the engine runs by generating amperage and recharging the battery while the engine turns the alternator. The voltage regulator is a unit that regulates the charging of the battery by the alternator and maintaining a certain amperage while the engine runs. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your charging system.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

The Ford Taurus “Check Charge System” light comes on if there`s a problem with the charging system and you`re running on limited battery power. Get to a mechanic right away to diagnose and repair the underlying problem.
The charging system warning light comes on when there is a problem with the electrical charging system or when the igni- tion switch is turned on with the engine not running. If the light comes on while driving, stop and check to see if the alternator belt is loose or broken.
LOSS OF POWER. Of course, losing power is the number one symptom of charging system failure. You might experience problems with dim or flickering lighting inside cabin or your headlights may become dimmer too. Certainly you`ll not be able to start the car if you lose power totally.
In most cases, a set of sticking or worn alternator brushes, a broken field control wire, corroded battery cables or a bad connection at the alternator or battery will cause an intermittent low-state-of-charge problem.
Another common problem that can cause the charging system to fail is a broken alternator belt or one that is worn so bad it slips badly. If the alternator works properly but the belt doesn`t spin it fast enough, the voltage output can drop and cause the system to act as though the alternator doesn`t work.
What`s happening when the battery/check charging system light comes on? Whenever this light goes on, it means that the vehicle is running solely on battery power. If the problem continues and your charging system fails, the battery won`t be able to recharge and it will soon run down, leaving you with a dead battery.
It is possible that the problems that you have been experiencing with the bad alternators have damaged the battery causing it to be weak. This would make the Battery Light come on. It is also possible that there is a problem with the fusible link or the alternator fuse for the charging system.
A blown fuse could be a cause of the battery light to come on. Excessive voltage in the electrical system can blow the fuse and prevent charging of the battery. A electrical technician can replace the fuse quickly and it an inexpensive fix.
The alternator belt is the connection that interfaces the crankshaft and alternator together. If your car`s alternator belt isn`t working properly, your car battery won`t get the charge it needs for your vehicle`s electrical parts. With that, your car battery light will frequently be on to indicate such an issue.
If your car`s “check charging system” warning light is illuminated, it means that there is a problem with your vehicle`s starting/charging system, which is usually indicative of an issue with your alternator, accumulator, or the battery itself.

Car shut down and will not start. Warning lights are on – 2006 Toyota Highlander
ANSWER : Hello. From what you describe, it would appear that your vehicle is having some sort of electrical issues. The "Generator Inverter Performance" warning comes on when the computer detects an issue with the vehicle’s electrical generator inverter. The generator inverter is the component that converts the high current electricity from the vehicle’s hybrid battery into a lower power form of electricity that is useable by the vehicle’s various systems.

The inverter is located in the engine bay, as the silver box on top of the engine. Unfortunately, the inverter is a critical component to the functionality of the hybrid system, and therefore to the operation of the vehicle, and, as a result, needs to be repaired or replaced before the vehicle will run again.

The VSC system warning light comes on when the computer detects an issue with the vehicle’s stability control system. This is usually due to a fault with the wheel speed sensors or the ABS module, though electrical issues can sometimes effect this system as well and cause it to behave erratically. I would start by taking care of the generator inverter issue and going from there.

I recommend having a certified mechanic, such as one from YourMechanic, perform an inspection to determine why the warning lights are on and suggest any needed repairs.

No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

My Accord gives out a "Charging system failure" warning. I drove home about 15 miles and then parked my car. After about 3 hours,
ANSWER : Hi there. On a new Honda Accord, the Charging System Failure warning light typically indicates a problem with the battery, alternator or other component inside the charging system of your vehicle. However, with less than 10,000 miles, this is most likely an electrical glitch or stored error code that was triggered. Since your car is "new", I would recommend contacting your Honda dealership first, to tell them about this warning light and ask them how they wish to handle this issue; as it should be covered under warranty. If they can’t help you, please set up a warning light inspection, and one of our mobile mechanics can come to your location and determine why this light came on.

Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light
ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit. For more help with these electrical tests, contact our service department.

ANSWER : Hi there, thanks for writing in.

It sounds like you are having a serious electrical malfunction, which is very hard to diagnose without being able to look at the car first hand. The first step to diagnosing your electrical issue would be to scan all the relevant control modules in the vehicle, to see if there are any faults relating to any of these issues. It sounds like somebody at the dealer has been trying to fix this problem, so it may be a more involved one. I have personally seen failed control modules cause things like this, but that is no guarantee that it’s the problem in your case. It would be best to have a qualified independent technician, such as one from YourMechanic, look at your car to diagnose your electrical problem.
