OK it's done! I put in the AC DELCO blower motor and now it does not burn the ground wire anymore to the blower speed control circuit. The motor WAS bad. The only thing is the new motor came with a shorter blower wheel height. Mine is a taller cage. So I swapped my old cage and put it on the new motor to keep the high air flow.
My only concern is that I noticed when the old cage is on the motor and spun by hand, the old cage has a slight wobble. The new cage does not when I try the same test. However when the motor is installed there is no rubbing or noise at all. Then fan works great and smooth.
My last QUESTION on this, is should I worry about the wobble on this plastic original cage (34 years old) that is the proper large size in height? Or is everything OK now? Like I said no more blowing even a 15 amp fuse when I think these motors take 20 - 25 amp fuses normally and no noise or rubbing and works smooth.
