Heavy Duty Alternator

In this Tech Tip, we’ll review how starter spacers are utilized as well as how to measure the starter flange to flywheel so that during any maintenance, the starter is properly mounted and performs as designed.

Experiencing problems with your alternator charging system? Squealing noises under the hood. Headlight bulbs that blow out repeatedly or dim. Dash voltmeter gauge out of range—either too high or too low. These are common indicators that something may be wrong with the charging system. If any of these symptoms are evident, then this video is for you. This video will walk you through five steps to pinpoint potential issues.

Have you ever installed an alternator that won't charge? The Flash the Field Tech Tip video will show you how to easily fix this alternator problem. This strategy only applies to the following Delco Remy alternator model families: 20SI, 21SI, 22SI, 23SI, 26SI, 30SI and 36SI.

While cranking problems can be frustrating, identifying and correcting the root cause does not have to be. The first step is to identify the symptoms. In a cranking system, you can divide your symptoms into one of three possible troubleshooting categories: 1. Slow Crank: The starter will crank; however, the engine RPM is slow to start the vehicle. 2. Click No-Crank: The solenoid clicks but the starter doesn’t crank. 3. No-Click No-Crank: The solenoid doesn’t click, and the starter doesn’t crank. In this Tech Tip video, we review the steps you need to follow to identify and then fix your cranking problem.

The Voltage Drop Test Tech Tip video explains how to conduct a voltage drop test on the battery, alternator and starter. Electrical problems related to excessive voltage drops are more common than you may realize. High or unwanted resistance is one contributing factor that leads to cranking and charging system problems. High resistance is often caused by one of these four main issues: - Loose connections - Corrosion in the cables and wiring - Improperly sized wiring or cables - Improperly crimped connectors A visual inspection of cables and connections doesn’t show what’s going on inside the cables or inside the connections. Voltage drop testing is the only sure method of determining if there’s an adequate delivery path for optimum starting, charging, battery performance, and life.

Proper installation of the pulley on a Delco Remy 24SI and 28SI ensures that the product will perform as promised. Unfortunately, damaged products are returned as a result of improper pulley installation. This shows you how to install a pulley in six simple steps.

Liftgates are an important tool on many trucks and trailers—however, they can quickly deplete the batteries used to operate them.Like other components, a liftgate adds to a truck’s electrical load. If the alternator is not equipped to handle the load, it can result in several issues, including: low battery state of charge, reduced battery life, poor liftgate operation, and possible starting issues. In this video, we review tips you should consider when selecting an alternator for your vehicle.

No one likes having to file a warranty claim, so we’ve done our best to make it fast and easy—and that starts with helping you understand what’s covered and what’s not. In this video we cover the top 3 claims not covered by warranty: 1. Trouble Not Found 2. Prolonged Power Applied/Extended Abutment 3. External Circuit Control Issues

When there are starter issues, you may think about doing a current draw test to pinpoint the issue. Yet, on a class 8 truck, a current draw test may not reveal what you need to know to fix your cranking problem. Plus, on these vehicles, a current draw test is more involved and time-intensive. And perhaps most frustrating—you often don’t get an accurate reading. That’s why the BorgWarner technical team recommends another diagnostic route to identify the issue and fix the cranking problem.
