Set me straight, On my Ford 640, 1 wire alternator Now 12 volt negative ground, Does the wire off the battery (starter solenoid) go to the positive side of the ammeter? And the wire from the alternator and ignition switch go on the negative side?

The way it was wired its the opposite of this and I would think the voltage would be reversed.

The ammeter is an indicator, not a controller.

Changing ammeter connections will only change the direction current flows through the meter and hence it's indication, it will not change the direction current flows through the circuit.

As stated, Ignore the + and - and connect it to indicate toward positive when running and charging

Quoting Removed, click Modern View to seeas Mitch said, if working correctly, what are you doing? Trying to fix it until it IS broke?

P.S. ammeters don't care about voltage, they care about amperes.

But it does matter in which the direction the amperage flows, whether it shows positive (charging)m or negative (discharge)

Is your ammeter currently working correctly? If yes, no need to switch anything. If your ammeter is not working correctly, switch the wires at the ammeter. Link is to a site with various wiring diagrams including a 601 with one wire alternator and ammeter. I know your 640 does not have a fuel gauge, but the wiring for the ammeter is the same.

Today's Featured Article - Two-Brush Generators - by Chris Pratt. Whether for product liability or because the aftermarket parts and labor business is lucrative, this concept is disturbingly prevalent. Fortunately when you step into your shop and make that jump 50 years back in time to work with your old tractor, this concept goes out the window. Even so, when it comes to the charging system, people quickly revert to this idea and start replacing the major components one at a time until it works. The reason you don't find any decals in your replacement set wit ... [Read Article]
