Voltage regulator – Is this an appropriate way to test a 7805 …

No that is NOT a proper or useful way to test 3terminal regulators. The technique is valid for SOME (but not all) kinds of transistors. But it is completely unsuitable for an integrated circuit like a 3terminal regulator. It will yield unpredictable (and most likely meaningless and misleading) results. If you don’t …

Alternator/Regulator troubleshooting – Era Replica Automobiles

The voltage output is governed by the amount of current in the field circuit, and is controlled by the Voltage Regulator. Current is fed to the battery and other power absorbers through the large Bat terminal on the back of the alternator. A ground connection on the alternator case completes the electrical circuit. There is also a  …
