Major Victory!!
I found the source of my lack of drive power. After a lot more ringing out of circuit and testing of resistances I found the culprit - a burnt contact on the reversing switch. It was on the pole that switches the armature and one side was still making contact, so when it was switched on it didn't connect across the switch as intended but through the resistors, giving the 6 V drop from gen. to motor. The motor now runs with lots of torque. I am embarrassed that it took so long to find the problem but at least it is found. Thanks for your help John and others.
