The modern reproduction ammeters are not as sensitive nor as accurate but they will function adequately. I recommend that folks not use the plastic covered finger nuts and just use regular nuts with lock washers. A loose connection will do damage to the meter.

As was mentioned previously, the 3-brush generator may need the 3rd brush adjusted to a happy place for best function. Ford recommended that an accurate ammeter be placed in the output line when adjusting the amperage output. Some folks adjust for daytime operation and some for night time operation. It depends on how much night driving is done. A person should run with lights on all the time for high output or the battery may be overcharged.

If the generator isn't functioning then it won't show a charge. A person has to make sure it's working so an adjustment of the brush is a place to start. Make sure all connections between the battery and generator are clean and tight. The battery is what regulates the voltage so this is critical.
