73 A57 Charger 400HP Electrical Issue On Start Up

[JG71B]

When I first fire the Rallye up, the ammeter gauge pegs to the right while warming it up. 1 or 2 pumps of the pedal and it always fires right up. After a few minutes, it centers back to normal. Should I be looking at the regulator or alternator going full field? It's seems to do it mainly when I first start it for the day and very seldom, if at all while it's warm out and about. Every so often it might do it if I'm in a store or something for a few and start it back up but it doesn't do it nowhere near as long as it does it at initial start up. Any ideas. Appreciate any help!

Battery, or battery drain?

Battery, or battery drain?

Never a battery issue or have had to jump this thing one time in 26yrs

I would still be getting the battery properly load tested and verifying the total current draw of the car while at rest.

No problem…. Fired my ‘68 up today,1st time in 6days. Pegged the amp gauge, 10secs later, almost dead center. Original style alternator. Had to crank maybe 6secs. How old is the battery?

I'll load test it etc tonight. Not sure how old it is honestly. I'll swap batteries with my 71 first and see what happens. Busy, haven't seen either in days
