Hello Customer it sounds like you have a charging system issue. I would have the alternator and battery checked. Low voltage will cause the gauge to jump back and forth.

i have a new alternator do you think it can be the battery
Expert:  KBB replied 7 years ago.

It's a very good possibility i would have it checked. If you have a volt meter you can go across the positive and negative to check voltage. I would also check voltage while the vehicle is running. Sometimes the remanufactured alternators can still be faulty because they only replace what is needed.
