Overcharging 68Dart...need some short fused help (pun intended:)

Thanks, I replaced this one because it just stopped charging period
A quick check for VR causing lack of to the rotor is to place a jumper from the "ign" side (power) to the controlled side "field".
If you haven't looked at this, posts 1, 2 and 5 show how it works.
Identifying Chrysler Alternators (1960-1976)



Here’s a pic of the VR106 next to the NAPA replacement. Ohm readings are a little different than the “original”, and one end of the coil is tied to the sense terminal through a 10 Ohm resistor? The coil wire is heavier gauge, and a little better wrapped.
That might be for the optional alternators that were wired a little differently. I've seen some Chrysler info on them but can't recall where off the top of my head.
