How to Diagnose an Alternator or Electrical Problem

Updated on November 9, 2016

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:

  • Car power slowly dies while you're driving.
  • Lights begin to dim.
  • Trouble starting car.
  • Car won't start at all.

What to Check to Diagnose Your Car's Electrical Problem

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.

You hook up a battery and turn the key to start position i dont get no dash lights or nothing at all. What do you think could be the problem with it

      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 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.

      Any suggestions?

      So I got a new battery last week, last night while running errands, I notice the gauge on my battery going down. By the way since getting new battery, battery light still on, gauge shows 12 until I drive for a minute, light goes out, gauge moves up to 15. Decide I better get it home, so I am not stranded. As I am driving, my battery gauge goes all the way left (dead), the rest of the panel all goes to the left, including speedometer. my headlights are so dim, I can barely see. I get it home, put it in park, wait for it to die, the dang truck is still running, even with everything dead, so therefore, I am not thinking its my alternator, as even though everything is dead, my truck is still running. I try to get my window up, nothing, turn off the truck. Now, I am completely dead. So my question is, is it the alternator?

      My 2004 Volvo s60 was making noise with the breaks so we took it to mechanic. He says the alternator is dead. This is possible as there are some warning signs such as dim lights, but the car is refurbished and the electrical was always bad. I find is suspicious that the alternator is bad when I can drive it from Indiana to FL without it dying, and then I drove it 45 minutes to and from work 5 days a week (sometimes 6) with no problems. What would you suggest? Thanks!

      My battery isn't getting a charge from the alternator. The car does start, and runs Briefly after getting a jump. The battery signal doesn't come on, but all of the other signals appear right before the car cuts off. I checked all the other connections and found nothing wrong. Even swapped the pigtail connection plug. I did have a oil leak, and some of it got inside the alternator. Could that be the reason the car won't stay running??

      I'm having a big problem with my 2008 GMC Sierra 1500. First, it would die out by having emergency blinkers on for about 5 minutes, or leaving door open with interior lights on for about 5 minutes. So I had the alternator& battery checked at O'Reilly's. They told me it was the alternator, so I replaced the alternator. A few days later, it started doing the same thing. So I took it back to O'Reilly's, to have them recheck the alternator. They told me it's the battery, so I had the battery replaced. I drove it for about 10 minutes, & it's doing the same thing. So now O'Reilly's is telling me I probably bought a bad alternator. Is there a fuse or electrical system I need to check.

      During this whole issue, the headlights are dimming like it's ready to die out, while running, & driving. Place help me! Thx

Then he had to get a new battery n it worked for a few days. Then it completely stopped working. He took the battery up to auto zone and they charged it to 100% n he got it home n it still wouldnt work. Why? What could be the problem? Thanks

      Hi, I have a dodge avenger 2008. I drove my kids to school this morning and I went downtown then I notice that my AND and slipper when wet indicator came on. Then ten minutes ten minutes later notice my radio went out. So I continued to head rob the grocery store everything still fine. At a stop light I shut the car off and turned it on again then the radio came back on. As I started the car and e mind into the drive the car stop and it cranked for a sec and then cut off again . Tried started several time wouldn't catch and shut down again. Finally after putting my feet on the accelarator am the gas pump it moved just enough for me to get it to a parking space on the street. However, tried to start it again it would not start at all. Could this be the alternator?

      As soon as i jump start the car, then i start driving the car. the lights start fading away that i have to keep pushing the gas for it to keep going than i turn it off and now it won’t turn on again. everything from inside the car works, then i noticed its been smelling like something is burning with some smoke coming out up front. My battery is new, the alternator has already been changed. what else could it be?

      Hey My son was driving his truck. The truck with his lights on going down the road just up and cut off on him. Well I automatically thought it's the alternator. I took his to a parts store and it checked good. I purchased a new one anyhow just cause I didn't know if the regulater in it was going in and out. Well. I put it on and jumped his truck off. Let it run for about an hour. Drove it down the road and all. Seemed ok. The voltage gauge was not moving where it needed to. I thought maybe it's just the gauge not reading. Well this morning it won't start. It's like it's a dead battery. Would it be the battery now before I go buy a new battery or something else ?

      I have an 1999 GMC SOnoma, that is acting funny. It has a new battery and all the bulbs work with no shorts, now start it up and run for a minute. And the lights start flashing or flicking but, not all the way off. The alternator gage is bouncing to the neg. side. I've checked the tightness of the belt and it is fine, the pulley is fine also. What can be wrong?

      I have a car that isn't my primary vehicle anymore. I didn't drive it all summer and the battery was dead when I started it up in Aug. I recently put (3 weeks ago) a new battery in. Didn't drive it until 2 weeks later....dead as a doornail. A mechanic said I needed anew battery and since I had it warranteed I put another new one in. Two days later dead again. I took it to the dealership Subaru and they recharged the battery and checked alternator and starter and said they are fine. What to do? I know it is going to die again. What should they check next?
