With a bad battery, stator or wiring issues, a new RR will not charge the battery. The battery must be fully charged and in perfect working order before installing a new regulator rectifier. Battery not charging? Might be time to replace your rectifier regulator. If the stock connector is brittle or melted and the terminals are corroded, it's best to replace them before installing the new part.
