We need more information.

Such as is the light on ALL the time or during pulls ONLY.

Also you need to do your own testing. You cannot assume anything. What is the voltage at the battery when the car is running. What is the voltage of the battery during cranking. These tests can help you find out if some other component is pulling the voltage down. ( Extra load)

Replacing parts blindly is not a good approach.
