Electrical Problem

Have a 2000 Ford Focus Wagon. Alternator light cam on several weeks ago. It was faulty so replaced it. Now the guages are going crazy and the battery is
over charging from time to time. The guages sweep an then bottom out and even the odometer goes blank. Anyone have similar problem.
