HIGH RESISTANCE IN CIRCUIT -- PLEASE HELP!!
To put this into a bit of perspective, let's say your regulator is "trying" to regulate properly at 14V In other words that's it's "setting." You are showing a 1.46 drop there at the ballast. This is going to get ADDED to the 14V of the VR so 14V + 1.46 is 15.46 is what the battery will be charging at, way too much.
I realize it's easy to get lost in this
This is yet another candidate for the "Mad electrical" article:

And in there is this simplified diagram:
This shows the simplified power in the car. Battery.........fuse link........through bulkhead........through ammeter..........to "welded splice"......and branching off to headlights, ignition switch, etc.
It does not show "back out" through the bulkhead to the ballast resistor. This is just simply one more terminal in the bulkhead connector.
ALSO: It is RARE but there has been cases where the welded splice has come apart. This is a factory splice in the black ammeter wire, wrapped in the under-dash harness a few inches from the ammeter, tucked up with the cluster.
If your troubleshooting indicates this might be it, you will have to pull the cluster, unwrap and cut open the harness, and inspect. Save that for "last" LOL
