FAQ

1. Will this alternator fit my Cummins 6BT engine?
This alternator (3935530) is the standard 24V 70A unit for the 6BT platform. However, we recommend verifying your original alternator’s mounting bracket style and plug connector to ensure a perfect physical and electrical fit.

2. What is the installation process?
Installation is straightforward for a qualified mechanic. Disconnect the battery, remove the belt, unbolt the old alternator, and install the new unit using the same hardware. Reconnect the wiring harness and battery, then test the charging voltage (should be approx. 28V at idle).

3. How do I maintain this alternator for long life?
Regularly check the drive belt tension and condition. Ensure all electrical connections are clean and tight. Avoid exposing the alternator to excessive water or steam cleaning. If the charging warning light appears, have the system tested promptly.
