Diagnosing Starter Cranking Problems

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.

Voltage Drop Test

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.

How to Install an Alternator Pulley

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.

High-Output Alternators for Liftgates

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.

Troubleshooting Starter Cranking Problems

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.

Measuring Alternator Current Draw

Measuring the current draw is the best way to ensure the alternator has sufficient output for all of the vehicle’s electrical demands. This video walks you through the steps to measure the current draw for a school bus.
