I have used that method also Jessie with sometimes good results. Using a 9 volt battery with jumper wires is a good jolt then reinstall a 1.5 volt AA battery to see if it works. Give that a try T-Sir to possibly revive Ben before having to do a complete rebuild.
BTW: I have also crossed the wires (+to- -to+) to jolt a particular stubborn motor in reverse first with good results. I also will note that once the motor runs, remove your jumper wires to relieve any chance that the 9 volts would burn out the motor.
