Will do--I have a soldiering iron, so I will give that a go just to be sure. I actually did re-twist the override plug wires, but it might lower the resistance a bit is I go ahead and soldier it.
To double check, to test the diode, I need to set my DMM on Volts, and put a lead on each end of the diode circuit, and then switch the leads, correct? One way should give me a reading and the other way should not (or at least a much lower reading), correct?

So to re-state your instruction for clarity, I take the pos. battery cable off, and put the negative DMM lead on the negative battery post (or on the frame for that matter since the neg. battery terminal just grounds to the frame anyway...), and the pos. DMM lead to every ground wire I can find in the system starting with the grounds closest to the battery. The first place where I get either an OL reading or 0.0ohm resistance back to the battery will give me the segment that has the problem. And resistance should increase the further I get from the other lead, I think. One thing I am not is and Electrical Engineer, so does this sound right?

5th Bike, and Easy Rider, thanks for all the time you guys have spent typing and thinking about this. I really do appreciate it.
