Installing one wire alternator

The accepted definition of a "one wire" alternator is that it has a special type of built in regulator and only has 1 wire---the large wire feeding to the battery, and of course ground

I don't particularly care for them for one reason.......you must have a big, oversized charging wire, because that one wire is also the SENSING wire, and with heavy loads, and additionally a low battery, such as after starting, in winter, or dark, running lights, heater, and so on, there can/ will be voltage drop on the charge wire. The voltage at the battery end will be lower than normal
