Dual Input IMS Starter

If you service newer trucks, you may have come across ones equipped with a dual input IMS starter. It is important to be aware of it so you can understand how it’s different so you can service it correctly. The dual input IMS starter has two wiring connection inputs, rather than one. These inputs provide both power (+12V) and ground. Together, they give the vehicle control over the power flowing in and out of the IMS when it is energized. This Tech Tip video reviews the differences between a dual input and single input IMS starter.

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.

Working with Electric Motors

Electric drive vehicles have high voltage electrical systems not found on typical vehicles powered only by gasoline or diesel engines. Because of this, it’s important to be aware of high voltage hazards before you inspect an electric motor. Specifically, be aware of the high voltage interlock switch. In this Tech Tip video, we provide a brief explanation of the high voltage interlock switch and explain how it works.

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.

Converting an on/off fan drive to a DuroSpeed™ Fan Drive

The DuroSpeed™ K32 Fan Drive is becoming the go-to fan drive for vocational and off-highway truck applications. Designed for harsh vocational applications, DuroSpeed provides reliable performance by having a higher disengaged speed to satisfy cooling demands. In this Tech Tip video, we explain how you can easily convert any BorgWarner K30 or K32 on/off fan drive to a DuroSpeed fan Drive.

Benefits of Oversizing an Alternator

When managing a fleet, the goal is always to get the most out of your equipment. We’ve got an innovative way for you to do just that: oversizing the alternator. Oversizing an alternator is a proven strategy that benefits you in three ways: 1. Fuel Savings 2. Longer Alternator Life 3. Better Battery life In this Tech Tip video, we explore these benefits.

Proper Off-Highway Equipment Washing

Cleaning off-highway equipment is a regular part of maintaining it. But did you know that if you are pressure washing, steam cleaning or using chemical degreasers, you could end up with a problem far worse than dust and dirt if you don’t clean it properly? That problem is corrosion of the starter or alternator. In this Tech Tip, we discuss how to avoid that problem and provide suggestions for how to properly clean and store your equipment.

Diagnosing Starter Systems Equipped with Smart IMS Starter

The diagnostic procedure of a starting system equipped with a Smart IMS is similar to any diagnostic procedure. It’s important to note that some of the Smart IMS features could be misdiagnosed as a starting problem. These features actually help protect the starting system.

Replacing Standard IMS with Smart IMS

With its many advantages, the Smart IMS is being adopted by more and more fleets. This video explains the simple steps to follow when installing a Smart IMS.
