First, I seriously doubt your WD has an aneomometer! LOL
But let's assume you're asking about the amp meter...
First thing to do is test the charging system with a volt meter to see if it is charging, and how much it is charging. If it is still 6 volt, with the engine RPM around 1500 or so, the voltage should be around 7.5 to 8.5 volts. If it has been converted to 12 volt, it should be about 13.5 to 15 volts.
Not being there to actually see what the amp meter is doing makes this a little hard to determine. But if the volt meter determines the system is properly charging, the simple diagnosis is the leads on the back of the amp meter need to be reversed. If the tractor has been converted from positive ground to negative ground, this has to be done for the meter to read properly.
If the volt meter determines the system is not charging or under charging, the problem could be a loose belt, or an internal short in the generator.
If the volt meter determines the system is over charging, the problem could be a defective regulator, poor regulator ground, or shorted wiring.

I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
