Battery or Altenator? Battery light came on, followed by ABS light. Radio lights went out then the panel lights went out. Headlamps dimmed to the point of almost being out. Indicator showed normal range, then went below the "L"as the system shut down. All this occurred after dark, so I parked in the driveway and shut it down. Nothing else done yet.

The charging system quit. Charge the battery at a slow rate for an hour, then have the charging system load-tested. You can also measure the battery voltage with the engine running. It must be between 13.75 and 14.75 volts.
