Alternator Capacity for 1968 Dodge Dart 270/SL-6
Sequence of pretty normal recharging immediately after start.
This is with a later squareback, a standard roundback probably would be a less current in the first minute, and take a little longer to recharge.
Batteries general do better recharging at lower rates, especially AGM's.
Engine idling around 1000 rpm.
Its worth mentioning here - The ammeter is labeled 'Alternator' but it only shows current to and from the battery. Its
not the alternator output.
