Does my vehicle need a new alternator? Signs that say yes!

Jimmy's Top Tech Auto • 16 June 2023

When the alternator isn’t working like it should, the battery’s power reserve can run dry, leaving you stalled out and needing assistance. To avoid such a situation, you’ll want to get to the shop when you first notice evidence of alternator trouble. At Jimmy’s Top Tech Auto, our local mechanics are highly experienced with alternator and auto electric repair in the greater Austin, TX area. 


Common Symptoms of Alternator Trouble

A dead battery is a problem that’s commonly associated with alternator failure. But just because your battery is dead doesn’t necessarily mean that your alternator is to blame. There are many other issues that can cause a dead battery, such as loose/corroded connections, old age, parasitic draws, and forgetting to turn off your headlights. But if it’s clear to you that none of these problems are present, then there’s a better chance that a bad alternator is the cause of the dead battery.


If the alternator isn’t working right, problems with electrical accessories can develop. Modern vehicles commonly have computers that can determine which accessories should have their power supply reduced when the alternator is malfunctioning. This way, power is saved for the vehicle’s most pressing electrical needs. However, this can cause issues such as power seats adjusting slowly or power windows taking longer to roll up and down. Alternator trouble can also cause problems with headlights and the radio. 


In many cases, the first sign of alternator failure is a dashboard warning light that flashes on with the letters GEN or ALT or in the shape of a little rectangular battery. Whenever a warning light gets triggered, it’s important to identify the underlying issue ASAP so it can be addressed before it gets worse.
