Not to Start All Over Again

Starting Problems? How to Tell If Information technology's the Battery or Alternator

If your vehicle won't start, it'southward normally caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It tin exist hard to determine if you're dealing with a battery or an alternator trouble. Hither's how to know which ane is the culprit.

Bad Battery Symptoms

If the cranking of the engine is sluggish, like your vehicle is harder to start on cold mornings, information technology starts inconsistently, or there's no audio and interior lights when yous try to starting time, suspect a declining battery, a loose or corroded connexion or electrical draw. A depression battery that has visible corrosion on the terminals is probably damaged.

If jumpstarting works, and so you know you've got a battery problem. Merely you also need to figure out whether information technology's simply at the end of its life or there are underlying bug. A expressionless or low battery can exist acquired by a declining alternator. It can also result from additional depict from auxiliary lights, fuses, sound systems, alarms and such.

Signs of a Bad Alternator

Some of the things to look for are no-starting and trouble starting, dimming lights and problems with stereo system output. If your car starts simply stalls when you're underway, your battery is probably not being recharged due to a faulty alternator. A squealing sound coming from the engine that gets louder when drains similar the heater or audio arrangement are on may be your alternator bearings.

Another telltale is turning the AM radio to a depression number on the dial without music, so revving the engine. If you lot hear a whine or the audio goes fuzzy when you hit the gas, your alternator is probably declining.

If the vehicle won't crank or start but the headlights are nevertheless working, expect to problems with the starter or other parts of the engine.

If yous have a check-engine or bombardment indicator light illuminated on your vehicle, it could indicate a problem with an automobile charging arrangement, or if your vehicle gets a jump-beginning and immediately stops running, information technology could exist an indication that the alternator is malfunctioning. It's of import to bring this into a professional for a proper diagnosis.

What the Battery & Alternator Do

An motorcar battery supplies a large electric charge that travels through the starting organisation and turns some gears to commencement the auto. Once the car is running, the alternator sends current dorsum to recharge the battery every bit you drive. Information technology supplies power for your machine's electronics when you're underway and makes sure the correct amount of charge goes dorsum to the bombardment.

If Your Motorcar Won't Start

The common signs above should help pinpoint what exactly is going wrong.

If you're non wanting to practise your ain diagnostics, get a jumpstart (and keep your vehicle running) and take information technology in for a technician to check your electrical system. Both the starting and charging systems should be inspected.

Bombardment checks on standard wet-jail cell batteries should include inspection of fluid level, the posts (the terminals marked + and -) for corrosion, and cables for snug connexion and no corrosion.

An electronic battery test should be washed, which gives more than information than a standard load test. It measures the voltage and common cold cranking amps (CCA). (Battery inspections and charges are free at Les Schwab Tires.)

The store should also check the alternator's voltage and current output and look for signs of bad diodes, the components that convert electrical electric current from Air conditioning (alternating current) to DC (direct current). If information technology's fourth dimension to supervene upon it and your vehicle has been customized with power-hungry aftermarket accessories similar a audio system, inquire if yous need a higher-capacity alternator.

If the alternator is working fine, the search for the problem volition move to other parts of the starting and charging system.

Got a Bad Alternator?

It may have damaged your battery. Since the alternator regulates how much electric current gets fed back to the battery during recharging, the battery may have overheated due to overcharging. This shortens its expected life and tin can make information technology unreliable. Ask whether you demand a replacement if you're having alternator repairs done.

If it's your battery that's bad, information technology won't damage the alternator.
