1969 Dodge Dart Overcharging/Undercharging

Electrical problem
1969 Dodge Dart 6 cyl Two Wheel Drive Automatic

I have a 1969 Dodge Dart with a 225 Slant Six and a 1920 Holley Carb.

1. My problem is that my car is overcharging significantly.

2. My alternator passed 2 different times at AutoZone (including the diodes, at least that’s what the print out says).

3. I also put on a new electronic voltage regulator, which is still overcharging at the same rate that the mechanical voltage regulator was overcharging at (the voltage regulator is grounded properly).

4. In park it charges at a higher rate.

5. When I put it in reverse it charges way below where it should be, and as soon as I put on the gas with it in reverse it does the same overcharging that it does in drive (acceleration).

6. Although, in drive, if you are at a stop light/complete stop it charges somewhat near where it should be.

7. However when in drive, after driving around for a while, it does seem to drop in rpm and in the charging rate. Also, it can drop well below where it should be charging. But as soon as you accelerate it overcharges again.

Does anybody have any suggestions?

Thanks,

Aaron
