I'm afraid that I can tell, just from looking at the photo, that this is a reproduction ammeter. That means it is very low quality. Some people have good luck with them, but most do not. :mad:

You can use it like it is by mentally figuring that where it is pointing right now is zero, and then adjust from there. You mostly need to see what the charge rate is with no lights on or anything (you are aiming for 6-8 amps). Other than that, you mainly want to see that you get some charge when running and that the cutout is working when at idle (not discharging your battery). The exact numbers are not that important (but it is nice for zero to be zero, if you know what I mean).

After you drive a car with a generator like a Model A for a while, you get used to looking at the ammeter as you return to idle to see the needle go slightly to the discharge side, and then jump back up to zero when the cutout opens. Then you know all is good. :)

While you keep using this ammeter, look for an original that has been restored. When you find a nice one, you can swap them out in a short time. Until then, keep driving and have fun! :cool:
