You mean there are people out there ignorant enough to wire in a winch, snow plow or other high amp draw THROUGH the factory amp gauge wiring? Even "I" would wire something like that in COMPLETELY SEPARATE from the rest of the system.

It is or was common to wire an electric winch or a plow to the battery. Many of them need the power (amps) that only the battery can provide. If wired to the alternator, battery power would have had been drawn through the ammeter and its wires anyway. Definately a better thought out system was needed for sustained high current equipment. At minimum heavier duty wiring, meter and connections, and a bigger battery.
