Remy Adds New Part Numbers To Starter And Alternator Lines
New starter part numbers are now available for a variety of light truck and van applications, including Ford F-250, F-350, F-450 and F-550; Chevrolet Express and Silverado; and GMC Savana and Sierra.
Alternator Testing Diagnostics Are Getting More Complicated
One test is not enough if you are diagnosing a charging system problem. All too often, if only battery voltage is present with the engine running the alternator is condemned as the source of the problem. If this is the case, it means that the alternator is not charging, but does not reveal why.
Alternator Testing: What Is The Correct Voltage?
For some alternators, it’s normal to see as low as 13 volts. For some, a constant 13.6 volts is an indication of a problem. For others, it’s normal to see as high as 16 volts for long stretches. Still, it’s perfectly normal for others to see the alternator not charge at all intermittently.
VIDEO: Check The Battery When Replacing The Alternator
Andrew Markel stresses the importance of checking the battery during an alternator replacement job, and replacing it if it is worn out or will not accept a charge. Sponsored by DENSO.
Computer-Controlled, ‘Smart’ Charging System Strategies: Why Volts Are Smart, But Amps Are Smarter
When diagnosing a charging system on any modern import, think “smart.” I learned this lesson several decades ago when repairing a cranking, no-start condition on a 1989 Honda Civic, which was equipped with one of the first “smart” charging systems. After verifying fuse continuity, I discovered that excessively high charging voltage had destroyed the Honda’s Engine Control Module (ECM).

Alternator Failures: Low Voltage To The Battery
One reason why alternators have a high failure rate is because they’re always working under a load. Generating electricity to recharge the battery, run the fuel pump, injectors and ignition system while powering all of the vehicle’s lights and electrical accessories places a substantial load on the alternator that generates a lot of internal heat.
VW Beetle, Golf And Jetta: Broken Tensioner, Root Cause Of Failure Is Alternator Pulley
This type of failure is the result of severe vibrations in the accessory belt drive system. While a broken tensioner may be the result, the root cause often lies elsewhere in the system.
