FAQ

Q: Will this alternator fit my Cummins 6BT engine used in a 1994 Dodge Ram?
A: Yes, this alternator is a direct replacement for the 6BT engine used in Dodge Ram trucks from 1989-1998. It matches the 24V/90A specifications and uses the standard 8PK pulley. Please verify your engine’s voltage system before installation, as some early models used 12V systems.

Q: What is the recommended maintenance for this alternator?
A: Periodically inspect the belt tension and condition (every 3-6 months). Ensure all electrical connections are clean and tight. Avoid exposing the alternator to high-pressure water washing. The unit is sealed, but excessive moisture can degrade internal components over time.

Q: Do you provide installation instructions or a wiring diagram?
A: While installation is generally plug-and-play for direct replacements, we can provide a generic wiring diagram upon request. We recommend consulting a certified technician if you are replacing the alternator on a non-standard application or if your vehicle has an aftermarket electrical system.
