Two weeks ago I had my alternator replaced. Yesterday while driving I noticed that my speedometer dropped and then returned to its original place and then the charge light flickered and then went out. This happened twice within an approx. 3 block area. I made it home and turned the off. Later I tried to start it and it gave a short impression that it was trying to and then click click - nothing. The same thing happened this morning. What kind of possible repairs am I looking at?
