I need some help ... I have reassembled my generator with new bearings , brushes , etc. ... and checked the windings for any shorts .... checked the armature .... but when bench testing it for motoring as I put 6 Volts to it the armature shaft freezes up..... you can not turn it buy hand .... no matter where I rotate the brush plate the armature shaft is locked up ...... HELP .... Joe Gallagher ..email@example.com
Did you connect the wires from the coils correctly. The MTFCA Electrical booklet says they must be crossed. If they are not crossed the magnetic fields are screwed up and it will not work.
Am I wrong in thinking that the 3rd brush must be lifted to motor the generator? Forgive me if that's in error.
Jerry you are correct, the third brush must be lifted off the commutator.
HI Guys .... Yes I did cross the coil wires and the 3rd brush is lifted ??? Joe
