What should voltage read at battery with tractor running?
Ammeter seems to function properly. Voltage at both posts, shows discharge with ignition on or lights on.
Forgot to metion that the genny actually charged but very weak before I took it to be overhauled.

A good and charged 6 volt battery ought to read around 6.3 volts setting, if hooked to a good charging system at high RPM it should rise to at least 6.5 and up to 7 +

Sometimes those switches dont have a good ground but when you dead ground the gennys FLD post she should still max high charge

Is the belt good n tight???? Genny have a good ground??? With gennys FLD grounded and if you jumped across the cutout at fast RPM if all else is okay but she dont charge well I STILL SUSPECT THE GENNY

Tried those ideas to JohnT, still no charge. The guy has already looked at it once since it was redone and he thought he fixed it. I guess I'm gonna take a loss and go somewheres else I have lost confidence in the guy. I'm already out over 200 bucks on it.

Perhaps incorrect field coils (6 versus 12 volt etc) or wired wrong, they splice in the middle, one end to third brush, other end to splice then out to FLD post....CHECK THAT OUT
