Assessing The Alternator

Facing car troubles with a new battery could point to alternator issues. The alternator charges the battery while driving. If it fails, the battery drains quickly, leaving your car unable to start. Regular checks ensure your alternator functions properly, preventing unexpected breakdowns.

When your car won’t start despite having a new battery, the problem might not be the battery itself. It’s time to consider the alternator. The alternator plays a crucial role in your car’s electrical system by charging the battery and powering the electrical components when the engine is running. If it fails, your battery won’t receive the charge it needs to keep your car running. Let’s look at how you can assess the alternator to get your car back on the road.

1. Listen For Unusual Sounds

Start by listening for any unusual sounds coming from the engine area. A failing alternator often makes a growling or whining noise. This sound can be a strong indicator that the alternator bearings are worn out.

Have you ever heard this noise but ignored it? It might be time to pay attention.

2. Check The Dashboard Warning Light

Most modern cars have a dashboard warning light that looks like a battery or says “ALT” or “GEN.” If this light stays on while driving, it could mean the alternator is not charging the battery properly.

Have you noticed this light but thought it was just a glitch? It’s worth investigating further.

3. Test The Battery Voltage

Use a multimeter to test the battery voltage. With the car off, the battery should read around 12.6 volts. Start the engine and check the voltage again; it should read between 13.7 and 14.7 volts.

If the voltage drops or remains the same, the alternator may not be providing enough charge.
