One wire alternator wiring? with OEM harness?

The problems with a one wire are not only with the crap OEM wiring, but related.

1....OEM wiring is not nearly large enough, not even "back then" was it

2...Deterioration over the years takes it's toll, ammeter and bulkhead connector

3....One wire alternators, even relatively small output, need a HUGE upgraded charge wire BECAUSE THE VOLTAGE SENSE is on that wire. Voltage drop when charging will let the system voltage sag
