Alternator and voltage regulator question

How do you have the charging line routed? ESPECIALLY with a "one wire" it's imperative that the line be oversized and good connections. Part of the reasons for this, is that the VR "sensing" is right at the alternator!!! This means that if the charging wire is a bit small, you'll have voltage drop between there and the battery. If your main loads are connected down closer to the battery, it may not run at proper charging voltage, IE the V drop on the charging line
