I've worked in a variety of hands-on professions and love to write about topics that can save readers from needless expenses.
Diagnosing alternator problems can be a bit tricky because the electrical system in a car comes from two places, the battery and the alternator. I'll give you a little background so you can understand what both systems do.
- The battery has one primary function, which is to start the car. It provides the high amount of voltage needed to turn the engine over. After the engine is running, the alternator takes over.
- The alternator is basically a generator that provides an even amount of low-level electricity, which it generates with a circular bundle of copper wires and a rotating magnet.
After the engine starts (thanks to the high voltage provided by the battery), the alternator provides the electricity required to power the car's many electrical functions, including the lights and radio, the spark, charging the battery, and others.
What Happens When Your Car Has an Electrical Problem?
When your car has an electrical problem you will notice any of the following:
- The car's power slowly dies while you're driving.
- The car's lights begin to dim.
- You have trouble starting the car.
- The car won't start at all.
What to Check to Diagnose Your Car's Electrical Problem
|Alternator||Battery||Spark Plug or Ignition Coil||Solenoid or Starter|
If the problem is a bad alternator, your car will slowly lose power. You'll be driving down the road, your lights will dim, and you'll lose power and die.
If the problem is with your battery, then you'll generally only have trouble starting your car since that's the battery's main function. Your lights may also be very dim.
When an ignition coil goes bad, the result is similar to a failed alternator: The car loses power and won't start.
If your car's solenoid or starter are bad, the lights will shine brightly but the engine will not start.
Once the alternator stops working, so do all of the electrical systems required to keep a car going.
Other problems can also cause a car to not start. It could be a bad starter, corroded cables, or a broken connection somewhere between the battery and starter.
When a coil goes bad there may be smoke or odor. Open the hood immediately and check.
A failed solenoid can make a clicking sound when you try to start the engine.
What Causes a Faulty Coil or Spark Plug?
Spark plug or coil problems can also make your car lose power and die. The ignition coil turns the battery's low voltage to the thousands of volts needed to create an electric spark in the spark plugs, which ignite the fuel. Coils can fail due to heat or vibration, or when there is a bad connection to the spark plugs.
As described above, when the coil goes bad, parts of it often melt and there's sometimes smoke or an odor. This will only really help you if you open up the hood immediately after it happens and check. If you check hours or days after the fact, then you won't be able to smell anything anymore.
Test Your Systems Before Going to the Auto Parts Store
Before you go out and order a new battery or alternator, test some of these different systems. If your alternator, coil, battery, or starter is bad, the car probably won't start, and it definitely won't be drivable.
Try to get as much information as possible so that you can get the right parts quickly when you go to the auto store. Depending on which system is bad, you should be able to fix it yourself.
Alternator Prices and Installation
Make sure that your current alternator is beyond repair first before getting a new one. Alternator prices can vary greatly by make and model, but generally speaking, new alternators should run around $250 without labor for installation.
If you're going to order and install the part for yourself, then it shouldn't be too expensive—just a few hundred bucks. If you need to have it installed by the mechanic, then the price might be a bit higher.
Depending on where your alternator is located within the compartment, the installation might only take an hour. But if the alternator is difficult to access, it might require removal of other parts and it could take many hours.

I have a 2002 chevy impala 3.4l v6 base model. My blinkers, 4ways, AND highbeam lights went out. I knew it wasnt the battery because i had power everywhere else plus just got a new battery a week ago. So i checked the alternator and it was good. So i checked the fuses they were good. So i replaced the relay and the whole blinker switch. When i started the car after installing these i had no break lights which i did befor the installation. Checked that fuse it was fine. Checked my blinkers and still no blinkers but everything else had power. Now as of yesterday i now have no horn. Please help me figure this out. I cannot posibly think of anything but a wire problem could be the problem. HELP ME PLEASE!

2002 Sebring sedan.....Battery is good and hold a charge. Alternator is steady at 14.1 volts......But the battery indicator light comes on every once in a while....Sometimes can drive 100 miles ok, other times it comes on in 10 miles. Always resets when I turn car off
Keep trying on March 19, 2019:
On many vehicles there is a fuse in the positive battery cable that goes to the starter. For example, in a 2003 Focus ZTW wagon there is an inline fuse in the positive cable and the connections on it can corrode. This will cause the battery to die while driving. Some have the fuse near the power distribution box. This problem will help flush several hundred bucks down the drain if your mechanic is a part swapper and not a troubleshooter. Good luck.

I have a 67 Satalite with a 1972 480 horse 360. I put in a new alternator, battery, and regulator. I can build engines but I'm a wiring idiot. When the car is of I have 12.4 volts. When I start the car, I have 11.5 volts at idle. As I rev the engine e I lose voltage. 1500 rpm I have 10.4 volts. At 2500 rpm I have 9.6 volt etc. The battery goes down after a few hours of driving. I have a MSD system. Any clues?

My toyota camry sxv20, 5s engine I started the car and then to check the lights when I switch the lights on there was smoke coming out of the alternator so I turn off the lights and put the engine off remove the negative terminal after like 5mins I put back the terminal and tried to start it it couldn't start it was like battery was weak. Is my alternator already bargered or my battery is bagered?

Cynjaz on March 27, 2018:
Hello, I have a honda 2008 accord (had it for two years) and this car has been giving me problems for the last year. I have changed the power steeting pump twice, crankshaft sensor once, the Knock sensor three times and both oxygen sensors twice. I was wondering if anyone is experiencing any of these isssues... for the last year about every 3 months or so, my car will take a bit to turn on. Once it is finally on, the AVS light will come on along with a flashing check engine light. Anywhere between 10-30mns after my car will loose power while driving, it will start jerking and will not go more than 5 miles per hour. We then changed basically everything we could possibly think of, at the time i was suggested to clean the oxygen sensors and put them back in there since it would be costly to be changing the sensors every three months and that seem to have fixed the problem. Well just a few days ago, we decided to replace both the oxygen sensors and sure enough by the following day my car started doing the same thing...jerking, loosing power etc.. my car is now at the mechanic shop and they are telling me that it can possibly be the fuel injector and there is two spark plugs that need to get replaced. has anyone experience this issue with the AVS light and check engine light? i also change the knock sensor last week, and that is the only code that we cannot remove. per the mechanic he believes besides the AVS+CHECK ENGINE that the car has a mechanical problem...he said that or the computer of the car is no good. Well as of today, he said he was testing the injectors and he moved the two spark plugs to the opposite side and now the computer shows different. I dont have too much detail since they are still testing the car but i just dont know what else to do with this car.

If my car sits 2 or 3 days it won't start, no lights no horn, nothing. When I jump it sometimes the heater will come on or my massage seat will come on. It is a 1999 Cadillac. It is a crap shoot whether the car will start again. What is causing this?
William Angle on February 22, 2018:
I have a 2005 Cadillac Deville (Base) with a North star engine and 220000 miles on it. All of a sudden when the car is moving forward the dash will reboot with all indicator lights (as if I re-started the engine) and at the same time all electrical systems have a momentary short, headlights and all lights blink, heater re-starts, every system. this will continue once every 30-seconds as long as the car is traveling (backward of forward) But does not seen to react to bumps on the roads or hitting a rough spot, the real issue is it can sit and idle for hours and not experience the issue. I have checked every fuse and eliminated most systems by pulling fuses and test-driving the car again, no change. Is this possibly an alternator voltage regulator, but I can run for hours parked, only when the car is moving do we get pulse about every 30 seconds and a car short - the engine continues to run through these momentary system shorts with no i please help me diagnosis this one

My car never had problems. One day I left my lights on all night and killed the battery. Bought a new one cause it wouldn't hold a charge after that. It was great for a week, then when I would turn the A/C, all gauges in the car would stop working and the A/C would start blowing warm air. I don't know what the deal is. I had AutoZone check my alternator and they said it was fine. After that I left my damn dome light on and killed the battery again. Now it's doing the same thing but this time it is not fixing itself. No matter how many times I charge the battery, it still messes up when I turn the A/C on or have too much electricity going at once. If my headlights are on, forget. Everything quits working, but the car doesn't stall? Any idea would be soo appreciated.

I have a 2010 Accent, I was driving down the road and my headlights, power windows, windshield wipers, and heat stopped working. All the dashboard lights worked as well as the radio. I pulled over, turned the car off and on, everything was working.....any ideas about how to fix this?? Check engine light came on too.

I have a 2003 Taurus. At very random times my car will die. I could be driving down the road, on the highway, or parked in a parking lot. All my dash lights will come on, the car will click for a few seconds, then I will be able to fire it up again. Sometimes it won't completely die, but will click a lot and my rpm gauge will drop to nothing then will bounce back up to where it is supposed to be and over and over again before catching and continue running. Recently before I start it, I have to turn the key to start and it will click for 10 to 20 seconds before I'm able to turn it over.
I have a new alternator and battery.

I have a 1998 Jeep Grand Cherokee Laredo yesterday got kind of hot outside so I turned on the air conditioner and I heard one pop noise almost like a backfire noise and then check engine light came on and I shut off the car and now it won't start. but when I give the car a jump start it will start but runs really shitty. after that I took a tester to everything and seems like the alternator is bad what would cause the pop noise and kill my alternator when I turned on my air conditioner?

I have a 2011 Ram. On 3 different occasions I have gone out to start and everything is dead. I barely get the jumper cables on and it starts right up. Runs and starts fine for weeks, no issues. Battery is less than a year old.
