  • The Power Behind your Engine (Alternator Diagnosis and Repair)

    Aug 16, 2020

    There's nothing like that sinking feeling when you turn the key and nothing happens in your vehicle.  A lot of us are quick to blame the battery.  But it may instead be your alternator that's failing.

    Your battery supplies power to start your vehicle, but the alternator is what sends power when your engine is running.  The good news is alternators last a fairly long time, and it's not unusual to get seven years out of one. But they can give up the ghost thanks to the harsh conditions in the engine compartment.

    Alternators have bearings inside them that keep things turning smoothly.  Debris, liquid, dirt and more can team up with the high temperatures your engine generates to cause those bearings to seize up.  That's not good, and if that happens, you may even be able to hear the bearings grind.

    Other symptoms of a dying alternator are a squealing noise in the engine compartment or your headlights may go dim and bright, dim and bright.  You might even notice an electrical smell.  Any of these signs warrants a trip to your service facility.

    Here's something else to think about.  If your alternator's bearings have seized up and the unit's shaft is not turning freely, that can destroy the belt that's attached to it.  So don't be surprised if your service advisor says both parts have to be replaced. 

    There are different grades of alternators you can buy, but consider just how important this part is to keep your vehicle running.  Your service advisor will give you options based on your driving style and vehicle.  Remember, if you notice any of those symptoms that may signal a failing alternator, have it taken care of before you wind up stuck somewhere at the side of the road.

    Affordable Transmissions Automotive Tips: Alternator

    Sep 9, 2018

    Your alternator makes electricity to start and run your engine and all of the vital electrical systems in your vehicle. That’s everything from the on-board computers to the turn signals. And of course there is the entertainment system, seat heaters, power windows and everything you plug into the power outlets. After your alternator makes enough electricity to do all that, it recharges your battery with what’s left over.

    When Brooklyn Park drivers constantly have a low or dead battery, the alternator is usually a prime suspect. However, the alternator is just one vital component of the starting/charging system, and a problem with any of the other components could be the actual cause.

    In addition to the alternator, the charging/starting system includes the battery, starter, serpentine belt system and all of the electrical cables that connect them. Your Affordable Transmissions service advisor has a systematic process of testing components and connections to get to the source of your trouble. The initial symptoms determine where to begin the diagnostic process, and he follows the procedure until he tracks down the culprit.

    For example, diagnostic tests at Affordable Transmissions could reveal that the alternator is not generating enough electricity to keep the battery charged. Is the alternator bad? Not necessarily. A worn serpentine belt tensioner could be allowing the belt that spins the alternator to slip. So the perfectly good alternator is not spinning at the proper speed. The solution for Brooklyn Park drivers is to replace the serpentine belt system – not the alternator.

    The good news for Brooklyn Park drivers is that our highly-trained technicians at Affordable Transmissions can properly diagnose all your vehicle troubles and make the necessary repairs to get you back on the road in Brooklyn Park.
