Re-read my post.

Shotgun testing is not the answer, it amounts to attempting to get lucky. Like playing the Lottery, not gonna happen. I don't have your chassis on my bench so I do not know the relationship of the "white wire".

Follow my post you should be able to zero in in on the section of the B+ that is drawing to much current.

By creatively removing the various loads from the B+ either live or using the VOM to monitor B+ resistance while un-soldering various loads. You did that with the white wire but that is just about the total load. Disconnect after the field coil.

Note I said VOM for the resistance measurements, a DVM could give erroneous readings in this application...

I can't recommend doing this as a live voltage test, the fault is drawing way to much current...
