Bypassing the Ammeter???

A lot of us have cars of the same age that show no evidence of overheating in factory connections. I believe those horrible examples shown at madelectrical have a history of addons like 8 track, CB radios, fog lamps, or even wrecks. Messing around with the batt post on the altenator while the battery is connected would cause a melt down too.
Bottom line, we have the info we need to repair these faults but it's not a manditory upgrade for every car.
