Can a bad battery cause an alternator to burn up?
Lets assume your able to start the engine, which means your starter is good, your probably firing on all cylinders, which means good ignition coils, and a good battery. If the battery were bad, then you wouldn’t be able to start the engine so the alternator couldn’t burn up?
What happens if you replace your alternator 3 times?
Replaced twice that would mean a total of 3 bad alternators, that is a serious problem. Lets assume your able to start the engine, which means your starter is good, your probably firing on all cylinders, which means good ignition coils, and a good battery.
Why is my alternator not starting my car?
If its going over 14.8 volts then your new alternator might be overcharging the battery. If you are positive that the alternator is working fine but still your car is not starting up then there might be issue with the starter motor (which i am sure the mechanic must have noticed)
How can I tell if my alternator is having an issue?
Your symptoms definitely shows issue with the Alternator or the battery. You can follow the below steps to make sure the Alternator is working fine. Ask someone to give the car some gas. On giving gas the voltage should read between 14.2 and 14.6 volts if its anything below 14 volts then your alternator might be having issue.
How long does it take for an alternator to go bad?
The typical lifespan of a new alternator should be between 5 and 7 years. If it has been that long and you have electrical issues, then your alternator is simply worn out and needs to be replaced. If you think it could be your battery that is at fault, the typical lifespan of a battery is between 2 and 5 years.

What’s the best way to replace an alternator?
That being said, most alternators follow these simple steps: Turn off your vehicle and disconnect the battery cables. Locate the alternator and the terminals on the back of it. Remove any terminal covers and then remove the bolts. Locate the tension pulley. Remove the alternator belt.
What causes an alternator to refuse to charge?
There’s other reasons for an alternator to refuse to charge; erratic connection in the dashboard warning light, weak link between the alt. and battery, etc. and even the belt can be an on and off thing. Yes it does. Also are those rebuilt alternators?
What causes the alternator to run full blast with no rest?
If something caused the alternator to run full blast with no rest, the unit could be fried. One possible situation that could cause this would be a battery with a shorted cell. The voltage regulator stops the alternator output when the charging voltage exceeds about 14V.
What causes an alternator to blow a fuse?
Another option is a high resistance short that causes a load that is heavy enough to permanently load the alternator but small enough to not blow a fuse. It may also be random bad luck.
How to troubleshoot an alternator and charging system problem?
If necessary, adjust the belt with the help of your car owner’s manual or repair manual. Inspect the belt for signs of cracks, cuts, shiny spots, deterioration or other signs of wear or damage. Change the belt and belt tensioner at the manufacturer’s recommended interval. 2. Check for Wiring Problems
What does it mean when an alternator light comes on?
If the light illuminates only intermittently, it usually indicates a loose or worn drive belt or serpentine belt, worn-out or bad carbon brushes in the alternator. But remember that the light doesn’t always mean there is a bad part; the light may be triggered by a sensor giving a wrong message or there’s something wrong with the circuit itself.
Why does my alternator get higher than base voltage?
You should get 0.5 to 2 volts higher than base voltage. If you are getting more than 2 volts above base voltage, most likely your alternator is over-charging the battery or the battery is faulty. Other potential problems are a faulty voltage regulator or a problem in the charging system wiring.
What happens when the diodes in an alternator go bad?
Alternators use diodes to rectify alternating current produced by the alternator into direct current. When one or more diodes go bad, the alternator can cause all kinds of problems. AC voltage leak can cause your lights to dim and drain power from your battery, for example.
