orig title: help: Legacy dash 9 started crawling
I have a CNW legacy Dash 9. It has been running fine for several years. Yesterday I had my neighbors seven year old twins over. Each had their own CAB and ran on separate loops. After about 10 minutes, the dash 9 suddenly would only run very slowly. I traded CAB's without any change. I then did a reprogramming to restore features. But the dash 9 continued to crawl along. The GE hybrid that the other twin was running ran normally.
I had 3 suggestions which I followed up on but none worked:
reprogramming to restore features
I oiled and greased the wheels
both motor/trucks assemblies are running
shut off the speed limit control
with the engine upside down in a cradle both trucks run when power is applied, but very slowly
in fact I can slow the wheels down by just applying a small amount of pressure with my clip.
The break slider is off on both CAB 2s
throughout everything the GE hybrid is running perfectly with both CAB twos
Being 89 years old and my hands being somewhat shaky I did not open the engine. However some younger members of the club will undertake this for me.
Aside from broken wires, any ideas about what might be wrong internally?
