Thank you guys (Steim/Moonman/Cjack/GGG) for all responding -
So Steim - That is a good information that i will note and check today. I will be sure and see if the DC motor that I received is in fact the Mabuchi brand and not a Pitman. If i cannot tell, I will take a picture of it but in the meantime, here is the picture of the DC motor that i removed. I will be sure to check the black molex connector for possible bad solder joints or broken connection terminations to the PC board of the DCDS.
Moonman - The photo of the DC motor that you provided is the rear motor and I have replaced the front motor with the magnetic ring glued to the brass flywheel. BUT that is a great point to make - I did NOT reset the loco and that is a plan i will do today as well. thank you for that. For the color codes of the wires, I pretty much matched to what I removed via a picture that I took prior to disassembling - When I felt the jerking of the front motor flywheel and with the rear motor flywheel, they both were turning opposite as they should and so I verified that the wires are correctly phased.
GGG - that was my first indication when I felt the small jerks, possibly a binding but there is no binding. both motors are turning freely. As satted above, the symptoms were a short 1ft burst of motion and stop and continue until you basically turn the Red CAB2 remote knob to zero. But of coarse there was the problem when i noticed there was no magnetic ring around the flywheel and it was in 8 pieces. I tried to tape them together to further my curiosity and there loco still a lot of jerking which is the culprit with all of the NorthSouth breaks. And both motors are reacting the same way with small incremental jerks. I will provide more photos.
Thanks -- Richard
