I am in the process of replacing the positive battery terminal and found an additional wire coming into the terminal.  It is heavy gauge and perhaps 1/4" diameter.  It has red insulation and is inside a black protective sleeve.  I am trying to figure out if the factory changed the wiring harness in 74 and placed the battery charge wire at the terminal instead of at the starter solenoid in the engine bay.  None of my previous Panteras had this setup but they are 71 and 72.  The wire in question is the one on the right in the photo below.  Thank you.

I bought this car a year or two ago and it has had a problem with hot restarts since I got it running.  I thought the source of the problem was old connections on the battery cable and decided to fix or replace each junction.  The first fix was the positive battery terminal as seen above and, wow, what an improvement.  The starter sounded like it was on steroids upon the first cold start.  The terminal might have been the primary issue but I will disassemble, inspect, clean, and repair (if needed) the junctions at the solenoid, the starter, and the chassis ground on the ZF.

Today I was able to verify that the hot restart problem is fixed.  I think the main issue was the positive battery terminal.  It looks like someone replaced the factory terminal twenty or thirty years ago.  Much of the copper wire was discolored.  I cut off about 3/4 of inch of copper (maybe less), removed some insulation, and installed the new terminal.  It is nice that hot restarts are no longer an issue.
