What is the white, crusty substance accumulating on my G2500’s battery post?

This buildup can interfere with the electrical connection between the battery and your G2500’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean a corroded G2500 battery terminal?

Regularly inspecting and cleaning your battery terminals will help keep your G2500’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables.
