1964 convertible charging question

I'm still getting used to my (new-to-me) 64 convertible, especially any of its idiosyncrasies. The battery recently shorted out while I was driving it, eventually bringing the car to a dead stop. I've replaced the battery, but now notice something that seems not quite right with respect to the amp meter. While driving along, the needle sits at dead center, dropping toward the discharge side when the brakes are applied, or when either turn signal is activated, or when the headlights are turned on. However, OCCASIONALLY the needle pops up into the charging side for short periods of time before eventually dropping back to the center position.

Is it possible (or maybe even likely) that the battery short has damaged something else in the charging system? If yes, what should I be looking at? Thanks for any advice.
 
I would change the regulator, especially if you using the original try a newer electronic one, if that doesn't do it, check the charge at the battery with a meter if its charging it's the gauge, (they have full current running through them) if its not charging, it's likely the altanator

My 63 Bird quit charging , I replaced the regulator, no charge. I started fooling with the wires. Using a teste meter and jumper wires, not togethet, and found I did not have a good ground. The two screws that hold the regulator were not grounding as they should be. Grounds are very important to the Birds.
