Alternator Rebuild

Is a Rebuilt Alternator as Good as a New One?

A properly rebuilt alternator using original equipment manufacturer (OEM) components can outperform many aftermarket new units. At Diesel Electric LLC, we disassemble each alternator down to its frame and rebuild it with the same OEM internal parts used during original assembly.

Unlike new mass-produced alternators that often rely on outsourced, lower-quality parts, our rebuilds exceed factory specifications by incorporating the latest OEM upgrades. With a rebuild, youre getting your vehicles original alternator housing, fully restored, upgraded, and tested to OEM amperage and voltage output standards.

Diesel Electric LLC's Alternator Rebuild Service

As a company thats been in business for decades, we know how to get the job done right. Our team of engine experts rebuilds alternators using a structured process based on your unit's specifications.

Here's what our process entails:

1. Initial diagnostics: We test the alternators performance and check key components before beginning disassembly.
2. Complete disassembly: The unit is taken apart down to the housing, with all internal components removed and inspected.
3. Core component testing: Major parts are checked for proper function and consistency.
4. Component replacement: Any parts that dont meet standards are replaced with OEM-equivalent components.
5. Reassembly and testing: The alternator is rebuilt, cleaned, and tested to ensure it performs to the expected output levels.

Unlike mass remanufacturers, we rebuild based on your unit's exact configuration rather than opting for generic part bin replacement. Youll get a high-performing alternator that's built to last.

What Are Common Signs Your Alternator Is Going Bad?

A vehicles alternator rarely fails without warning and usually shows clear signs well before a rebuild is necessary.

The most common symptoms include:

• Dim or flickering headlights
• Battery warning lights
• Dead battery
• Electrical malfunctions
• Grinding or whining noises
• Burning smells

If you notice any of these warning signs, it's essential to act promptly.

How Long Does It Take To Rebuild an Alternator?

Rebuilding an alternator typically takes 24 to 48 hours, depending on the unit type, its condition, and the availability of required components. Although we aim for an efficient turnaround, we focus on doing the job thoroughly and to the highest standard. For added support, we also provide roadside assistance in the event of an alternator failure while you're on the road.
