Tech Tip: Toyota Charging Improvement at Idle
Some customers with a 1998-2003 Sienna may complain of a low battery or no-start condition after running the engine at idle or low RPM for extended ­periods of time with several accessories on during high-temperature conditions. A new alternator has been developed to improve charging performance at idle. More
Avoiding Alternator Comebacks: Did Your Supplier Provide the Right Pulley?
Automotive repair businesses that install remanufactured alternators are urged to verify that their units are equipped with overrunning alternator decoupler (OAD) pulleys for the growing number of late-model vehicles now requiring this advanced technology. More
Tech Feature: Breezing Through Ignition Off Draw Tests
One of the biggest differences in servicing the Sebring convertible from other Chrysler models was its battery location - behind the driver's side wheel well. More
Tech Tip: Be Careful When Handling Alternators with Floating Stators
Some original equipment alternators made in recent years feature a "floating stator" that is more sensitive to proper handling than previous designs. "The stator, or set of windings that surround the rotor, is press fitted or in a very tight tolerance situation in most alternator designs," said Fred Padgett, group product manager for starters and alternators for Bosch.

Diagnostic Dilemmas: Taking Charge of Vehicle Voltage Testing
Although checking charging voltage at the battery terminals is the most popular method for testing an alternator, a charging voltage test seldom reveals less common problems like open or shorted alternator diodes, intermittent high or low charging rates, charging system wiring problems, intermittent cranking/no-start complaints or intermittent dead battery complaints. In addition, testing charging... More

Alternators & Starters: How and Why These Hard-Working Components Fail
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, and power all of the vehicle’s lights and other electrical accessories places a substantial load on the alternator that generates a lot of internal heat. This can burn out the diodes in the... More
Power Your Profits with Performance Mods
