Good to Know

Always disconnect the battery first to prevent shorts, and take a photo of the belt routing before removal to save yourself headaches later. While you’ve got the belt off, check its condition—a worn belt can cause charging problems even with a new alternator. Clean all electrical connections with contact cleaner before hooking up the new unit for the best performance.
