Hi,
My Toyota Hiace has an external voltage regulator connected to the alternator. It is the type with 6 wires, a black box the size of a fist and the internals are made up of 2 large relays.
When I run the van, the voltage is not very steady, it fluctuates up and down maybe 1V when I continously measure the battery voltage through my cigarette plug while driving. My modern Toyota Corolla has a modern internal regulator and the voltage is rock solid at all times no matter what.
Is it normal for old school external relay based regulators to show a fluctuating voltage of 14 V +/- 1V? Can anyone confirm that or should these regulators also be rock solid?
