What are the Symptoms of a Failing Alternator?

Many drivers are not aware that the alternator is a key component in your car's electrical system.  What does it do, you ask?  Simply stated, it turns the energy from the crankshaft into useful electricity to power the vehicle's electrical systems and to help the battery recharge. When the alternator starts to fail, it can create a domino effect of electrical issues that can eventually cause a breakdown.  The issue is that it is often difficult to determine whether a failing alternator, a weak battery, or a bad car starter is the culprit.

So what are the symptoms of a failing alternator?  Here are 6 signs that are easy to notice:

1. The indicator light illuminates on the dashboard titled "ALT" or "GEN.”
2. Dim headlights generally mean the alternator is struggling to perform.
3. Other electrical systems that are powered by the alternator may start to act up, including power windows, power locks, dashboard lights, air conditioning, car radio, GPS, and etc. 
4. Sometimes Alternator failure can cause some of the bearings to fail in the engine, creating rare rattles and noises. 
5. When the alternator is failing, there might not be enough power in the spark plugs to keep the engine alive, which can cause it to stall for no reason while running.
6. The battery sometimes will be drained of its charge because the alternator is not capable of recharging it.

If your vehicle is getting hard to start, for driving safety, performance, and peace of mind, have the car starter, the battery, and the alternator checked as soon as possible.  Don’t delay until you are suddenly left stranded somewhere before taking care of starting issues.

Wondering what are the Signs of a Bad Car Starter?

All of a sudden, your car won’t start!  Is the culprit the battery, the starter, or the alternator?  It could be that the battery doesn’t have sufficient charge to start your car.  Or possibly, the alternator isn’t sending power to the battery.  The smart thing to do is to head to your auto shop and ask for a thorough inspection to determine the cause and rule out other problems.

So just what are the signs of a bad car starter?

1. Clicking sound when you turn the key in the ignition.
2. The lights come on, but the engine won’t start.
3. The engine doesn’t crank.
4. The starter has overheated and smoke is coming from the car.
5. The starter is soaked with oil. 

There are some other causes that may result in a starter going bad:

• Loose wiring
• Dirty connections
• Battery corrosion
• Damaged parts in the starter system
• Oil leaks

Tip to Remember:  Don’t wait to get stranded with a car that won’t start.  If you have started noticing starting issues, have your car inspected out as soon as possible before it leads to other car issues.
