All agreed, but also, with a good battery and the headlight ammeter, if it is left of center, you are discharging the battery. At center, you are fully charged and at the cutoff voltage of whatever regulator you have (including Zener). If right of center, you are not fully changed and are charging. With a good ammeter it's basically the same but you can usually accurately measure the current in or out.The original headlight ammeter was half decent (not great), the current ones have no damping so are barely usable. Some of them tend to fall apart in operation - really bad since one side it directly connected ot the battery. Also, since they are really a voltmeter that reads the voltage drop across an internal coil of wire and are crudely made, there's no point of discussing actual readings and where I say center, I mean whatever is center when fully charged and at riding RPMs.
