1983 300SD. Charging warning light started flickering, brighter at idle, almost no illumination at 2500 rpms. Started losing headlight power, turn signal strength, etc. on the way home. Got home, battery dead. Charged battery overnight.
This morning: Battery volts with engine off - 12.5 volts. Battery voltage with engine at idle - 14 volts. Charging light still flickering. Cleaned battery posts and terminals, cleaned wiring junction block on frame near alternator. Light on dash still illuminated at idle.
Any thoughts?
