anybody know the diameter of the generator pulley for a 1949 zau...mines 4 inch diameter...does this sound right....the belt runs close to the chassis and only seems abit smaller diameter than the crank pulley...?? not sure if its been changed in the past...the tractor is new to me...it seems you have to get lots of rev to make it have any generator output..im wondering if its spinning to slow perhaps if it is wrong pulley...its now on 12v pos earth setup??
 
Should be closer to 3" diameter but I don't have one handy to give you an exact dimension.
