The Top 4 Signs Your Alternator is About to Fail

When you think about the power source for your vehicle, the first part that comes to mind is often the battery. However, the alternator is the true powerhouse, responsible for charging the battery and powering nearly all your car’s electrical components while the engine is running. Ignoring the early warnings of a failing alternator can lead to a sudden breakdown, which is exactly what we help our New Jersey community avoid. We want to empower our clients with the knowledge to spot trouble early.

1. The Dashboard Battery Warning Light Is On

This is the most direct warning sign your car gives you that a problem exists within the charging system. That little battery icon doesn't just mean your battery is weak; it signals that the voltage output from the alternator is either too low or too high. When this light illuminates, it means we need to check the alternator's performance right away to prevent a complete loss of power and an expensive tow.

4. Your Vehicle Has Trouble Starting or Frequently Stalls

If the alternator isn't properly charging the battery, the battery will eventually fail to start the engine, even if it is a new car battery replacement. If our car starts and then immediately stalls, it's a strong indicator that the alternator is not sustaining the necessary electrical flow to run the ignition and fuel systems. This is an urgent sign that we need mobile service repairs immediately before you get stranded.
