An alternator may smoke due to several reasons, primarily overheating caused by excessive electrical load or a short circuit. Worn bearings or internal components can also create friction, leading to overheating and smoke. Additionally, a faulty voltage regulator can cause overcharging, resulting in insulation breakdown and smoke. If an alternator is smoking, it is crucial to address the issue immediately to prevent further damage.
What else can I help you with?
Will a bad alternator cause new spark plugs to smoke?
Spark plugs don't smoke. A bad alternator would cause a dead battery.
Why does the alternator smoke and makes a nose when its cranked on a2006 dodge charger?
It is defective or the alternator belt is loose.
A little puff of smoke from the alternator but the battery light is?
You have an electrical fault in the alternator. Don't drive the car, get this fixed, or you risk a fire.
Do alternator for a 98 voyager make it smoke?
not unless its froze and the belt is smoking
What causes alternator to get hot and smoke with key off on a 1990 ford escort l x?
Could be internal short or defective voltage regulator (points not opening) located in alternator
Could a short give the same symptoms as a bad alternator?
No, a short involves massive amounts of smoke, and usually glowing red wires.
Why would the voltage regulator smoke after replacing the alternator on a 79 Lincoln Continental?
The voltage regulator may smoke after replacing the alternator on a 1979 Lincoln Continental due to a short circuit or incorrect wiring connections made during the installation process. If the alternator is faulty or if there is an issue with the wiring harness, it can send excessive voltage to the regulator, causing it to overheat. Additionally, a malfunctioning regulator might not properly manage the voltage output, leading to damage. Ensuring all connections are secure and components are functioning correctly is crucial to prevent this issue.
How do you know your alternator needs replacing?
In my case the bearing went bad and "froze" making a loud noise and making the fan belt smoke. If it does not make a noise, check the voltmeter on your dash - failure to charge could indicate the alternator is not working, but I think others things are more likely . It should be easy for a mechanic to test to see if the alternator is charging.
Any ideas as to why a 1998 Toyota Camry the battery fluid boiled out the engine would not shut down and smoke was present under the hood?
12volt regulator on alternator is blown, causing high output from alternator and could have blown the input circuitry of your fuel injection computer.
When you drive your 2000 elantra you notice that smoke comes out of the battery top vent you changed the battery and this is still going on does anyone know what could be the problem?
The alternator is probably over-charging the battery. Replace the alternator if the voltage at the battery terminals is over 15V when the engine is running.
Does an alternator get hot?
yes if it has a fault. Either a bearing has gone - in which case you should hear a noise. Or the rectifier has a fault (probably a short circuit) in which case things can get very hot and you will see smoke.
