Default Gauges going haywire

I have 2000 Cherokee Sport. Recently my gauges started acting weird. Alternator gauge pegs to the overcharging side, now today it's showing discharge to 0. I installed rebuilt alternator in February, when I changed the water pump. The airbag light comes on. The check gauges light comes on. The speedometer is all over the place , that started today., along with the engine light coming on. Anybody familiar with this problem?

Could be a loose or dirty cluster connection.

Thanks. I'll try some CRC Electronics Cleaner on those connections.

Check the alternator connections. Climb under there and get your hands on them. Pull, tug, push, and generally annoy them. I'm betting you'll find something loose.

Yep... Or a bad ground to the body/chassis.
