Sometimes the engine won’t crank even though the starter will spin. A dying alternator may also cause your car’s radio and internal lighting to stop working. You might use the opportunity to recommend a higher-output alternator if the customer’s vehicle is equipped with a megawatt aftermarket sound system or other high-load electrical accessories. Circuit resistance can be checked by connecting a volt meter to the positive battery terminal and the positive terminal on the alternator. It’s difficult to see how much the grooves on the underside of the belt may be worn, so belt manufacturers have created special belt wear tools that can check the depth of the grooves to reveal how much they are worn.The operation of the automatic belt tensioner also should be checked to make sure it is working correctly and is capable of maintaining proper belt tension. Unlike older belts made of less durable rubber, they don’t crack with age. Original equipment belts made of EPDM synthetic rubber are high-mileage belts capable of lasting upward of 100,000 miles. Reviewed in the United States on February 23, 2011. It can also result from increased internal friction due to shaft bushings that bind or an armature or magnets that are rubbing inside the starter.A loose starter may crank an engine slowly, noisily or not at all. Squealing, howling or grinding noises coming from the alternator are indicators of bearing failure and eventual failure of the entire alternator unit.Modern vehicles require a steady electrical current of specific voltage in order to run properly. Today’s computer-controlled charging systems tailor the charging rate not only to the electrical demands on the battery and alternator, but also to changing driving conditions. Highest output available for a Remy Premium Remanufactured Alternator. Superior performance . But replacing an OAP or OAD pulley with a solid pulley defeats the purpose of the original pulley and may result in increased NVH, reduced belt and tensioner life and customer complaints.When a new or remanufactured alternator is installed on a high-mileage vehicle, recommend a new drive belt too. Each time the vehicle is started, the battery uses some of its charge to turn the engine over. Replacing an OAP or OAD pulley with a less expensive solid pulley is possible, and some replacement alternators come with a less expensive solid pulley installed rather than an overrunning clutch or decoupler pulley. Other Electrical Problems The alternator is responsible for providing power to your car’s different electronics. Verified Purchase. So really, your choice was; spend $450 at the dealer or $125 at the auto parts store for a rebuilt. There was a problem filtering reviews right now. 99. This is the best remanufactured alternator you can get. From $99. If the alternator fails the tests, your customer needs a new or remanufactured replacement alternator. The alternator is a relatively simple component containing only a few parts, but it plays a critical role in the operation of any gasoline-powered vehicle. View Details Remy Platinum 100% New Alternator (3) 2.3 out of 5 stars. This reduces noise, vibration and harshness in the belt drive system, but may cause a charging problem if the clutch slips when it should be gripping.Another type of pulley is the Overrunning Alternator Decoupler (OAD) pulley. Problems with other sensor inputs or a defect in the control module itself may prevent the alternator from charging properly.A slipping drive belt is another common cause of undercharging, especially with V-belts on older vehicles. You might use the opportunity to recommend a higher-output alternator if the customer’s vehicle is equipped with a megawatt aftermarket sound system or other high-load electrical accessories.If the alternator passes the tests, the problem is not the alternator but something in the wiring or the charging system control circuitry. However, I'm not a big fan of how much "flicker" I can see in the lighting sometimes. Inside an alternator are bearings critical to the alternator's smooth operation. Smells Smell burning rubber?
Overrunning Alternator Pulleys (OAP) are used on a number of late-model import and domestic vehicles. It provides the high amount of voltage needed to turn the engine over. Higher electrical demands on charging systems have increased alternator failures.A good battery should be capable of accepting and holding a charge from a battery charger, and should be at least 75 percent charged (12.5 volts or higher). Drops in electrical output from a failing alternator can cause these systems to malfunction, leading to a poorly running engine. Most likely it's one of many possible alternator problems, and without some attention, the alternator can cause car trouble ranging from slow starts all the way up to a dead car. The same test can be repeated using the battery negative terminal and the alternator housing to check for excessive resistance on the ground side of the circuit.If the wiring checks out okay, the problem could be in the voltage regulating circuitry inside the powertrain control module.
