Usually a smooth even RPM when you jump voltage to the ARM post and case/frame (with FLD grounded) means the Armature, Brushes and bearings/bushings are in "decent shape" Then if it increases RPM when FLD is ungrounded that means the Field windings are at least intact. If she dont change RPM at all I question if the Fields are bad such as open or shorted internally. An ohm meter can provide an indication if the fields are open or shorted.

That noise may be a bearing/bushing "going" bad although it isnt bad enough yet to allow the armature to drag.

I prefer a battery for the motor test but still think it should act about the same as above unless the charger can barely supply enough amps to begin with.

Heres my non chargign troubleshooting
