Take it to your local Advance auto parts store and have them check your charging system for free. If it's not a regulator or alt. problem then it's the same ole common problem of those cheap gauges failing and since it has age now, I'd be willing to bet it's just that gauge.

You say the new gauges are bouncing too? If the alt and reg are o.k. and the new volt or amp ( you did not say which you got) are still bouncing I am at a lose for a cure. It is stock aint it? No under drive alt. pulley's or the likes?

Make sure regulator has a good gound to firewall and I add a braided grounding strap from the back of the head to one of the mounting bolts on the regulator. Clean the contacts in the regulator plug and I've had to crimp the loose connector contacts from the outside slightly to get better contact. My didn't jump, but my would chare than discharge and when I reseated the regulator plug it would charge again.
