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.

Joe,

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.
